I will send this in a series of emails to make the discussion more manageable. I have many comments - so lets please move fast so we can shoot for a new publication. comments: 1) This is a general comment i made in the previous release. The change did not make it in properly. a) Define what is a downstream and upstream LFB means. While the terms are mostly used (with exception of a few places), the definition needs to be in place. Put either in beginning of section 5 or in section 2. b) Be very precise about the different meanings of LFB port vs physical port vs virtual interface port etc. I would suggest you audit the document in full and fix this. 2) Other general comments: a) please be consistent in the document in your usage of terms. i) next-hop vs nexthop vs next hop b) InvalidIPv4SrcAddrCasexxx I believe there are proper terms for these terms. Can we find the proper terms and replace these generic terms? Example appropriate terms are "martian" and "bogon" packets. c) Section 5 text has improved greatly - general comments (more specific comments to come later): i ) In "data handling" sections, often the text mentions a table but does not mention what is the lookup key or index that is used to look at this table. ii) There is a lot of repetion of text between the data handling and description of the LFBs. The data handling should be describing things in general and may reference components. The component section on the other hand should not try so hard to describe the data handling. cheers, jamal From hadi@mojatatu.com Sun Aug 7 09:29:21 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id C95AD21F8748 for ; Sun, 7 Aug 2011 09:29:21 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.027 X-Spam-Level: X-Spam-Status: No, score=-102.027 tagged_above=-999 required=5 tests=[AWL=0.950, BAYES_00=-2.599, FM_FORGED_GMAIL=0.622, RCVD_IN_DNSWL_LOW=-1, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id frFddxe6cKfv for ; Sun, 7 Aug 2011 09:29:21 -0700 (PDT) Received: from mail-fx0-f44.google.com (mail-fx0-f44.google.com [209.85.161.44]) by ietfa.amsl.com (Postfix) with ESMTP id 32A4421F8742 for ; Sun, 7 Aug 2011 09:29:21 -0700 (PDT) Received: by fxe6 with SMTP id 6so1225146fxe.31 for ; Sun, 07 Aug 2011 09:29:44 -0700 (PDT) Received: by 10.223.76.71 with SMTP id b7mr6203938fak.30.1312734584121; Sun, 07 Aug 2011 09:29:44 -0700 (PDT) MIME-Version: 1.0 Received: by 10.223.155.199 with HTTP; Sun, 7 Aug 2011 09:29:24 -0700 (PDT) From: Jamal Hadi Salim Date: Sun, 7 Aug 2011 12:29:24 -0400 Message-ID: To: forces@ietf.org Content-Type: text/plain; charset=ISO-8859-1 Cc: Chuanhuang Li , "Joel M.

The data handling should be describing > things in general and may reference components. The component section > on the other hand should not try so hard to describe the data handling. Yes, we need to refurbish the text. Whereas, we may have to face the fact that the text for data handling and the components are in many cases highly cross referred. For data handling, it is very hard to describe things clear enough without explaining some components. For some components, it is hard to make clear without saying its function to data, which is actually on data handling. > > > cheers, > jamal From wmwang2001@hotmail.com Mon Aug 8 07:33:46 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id DBDA121F8A80 for ; Mon, 8 Aug 2011 07:33:46 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.669 X-Spam-Level: X-Spam-Status: No, score=-1.669 tagged_above=-999 required=5 tests=[AWL=0.929, BAYES_00=-2.599, STOX_REPLY_TYPE=0.001] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id zYqxrIubnlBo for ; Mon, 8 Aug 2011 07:33:46 -0700 (PDT) Received: from snt0-omc1-s29.snt0.hotmail.com (snt0-omc1-s29.snt0.hotmail.com [65.55.90.40]) by ietfa.amsl.com (Postfix) with ESMTP id 5822B21F8715 for ; Mon, 8 Aug 2011 07:33:46 -0700 (PDT) Received: from SNT132-DS17 ([65.55.90.8]) by snt0-omc1-s29.snt0.hotmail.com with Microsoft SMTPSVC(6.0.3790.4675); Mon, 8 Aug 2011 07:34:12 -0700 X-Originating-IP: [220.191.254.66] X-Originating-Email: [wmwang2001@hotmail.com] Message-ID: From: "Wang,Weiming" To: "Jamal Hadi Salim" , References: In-Reply-To: Date: Mon, 8 Aug 2011 22:34:04 +0800 MIME-Version: 1.0 Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal Importance: Normal X-Mailer: Microsoft Windows Live Mail 14.0.8089.726 X-MimeOLE: Produced By Microsoft MimeOLE V14.0.8089.726 X-OriginalArrivalTime: 08 Aug 2011 14:34:12.0507 (UTC) FILETIME=[3DCD66B0:01CC55D8] Cc: "Joel M.

The definitions below are repeated for clarity. since a lot of the definitions do not appear in the early RFCs. Also we can (and probably should) add the following definitions (which are used in the lfb-lib document): FE Model: The FE model is designed to model the logical processing functions of an FE. The FE model proposed in this document includes three components; the LFB modeling of individual Logical Functional Block (LFB model), the logical interconnection between LFBs (LFB topology), and the FE-level attributes, including FE capabilities. The FE model provides the basis to define the information elements exchanged between the CE and the FE in the ForCES protocol [RFC5810]. Data Path: A conceptual path taken by packets within the forwarding plane inside an FE. Note that more than one data path can exist within an FE. Also in the model rfc there is the following definition. While we don't use the terminology of LFB Class Library I think that it is good to have it here as that is what we're doing. LFB Class Library: The LFB class library is a set of LFB classes that has been identified as the most common functions found in most FEs and hence should be defined first by the ForCES Working Group.

This paragraph may need more discussions. thanks. Here's my understanding of the simple case on a host system: Typically on an ethernet Network Interface - there is DMA buffer (could be in the simple case be modelled as a queue) per MAC per direction. Modern interfaces with virtualization etc will have more than one but thats out of scope here. i.e in the simple case there will be one such buffer space for EtherMACIn and another EtherMACOut per physical port. Flow control to the other peer is generated when rx side (EtherMACIn) buffers either are past certain threshold or exhausted etc. So i think something is missing in the discussion text. So do we need to define these queues? They should be read only I think since i dont think they change once the device boots up. cheers, jamal From chuanhuang_li@mail.zjgsu.edu.cn Thu Aug 11 18:55:24 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 6A54921F8AAF for ; Thu, 11 Aug 2011 18:55:24 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: 0.001 X-Spam-Level: X-Spam-Status: No, score=0.001 tagged_above=-999 required=5 tests=[BAYES_50=0.001] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 1Pfi2lXmtdkb for ; Thu, 11 Aug 2011 18:55:24 -0700 (PDT) Received: from mail.zjgsu.edu.cn (ucmail.zjgsu.edu.cn [124.160.64.1]) by ietfa.amsl.com (Postfix) with SMTP id AC77221F8A91 for ; Thu, 11 Aug 2011 18:55:21 -0700 (PDT) Received: from RobinLee (unknown [10.20.0.167]) by mailportal (Coremail) with SMTP id rBCI85D74C1zh0ROgI1bAA--.33373S2; Fri, 12 Aug 2011 09:52:51 +0800 (CST) Date: Fri, 12 Aug 2011 09:59:07 +0800 From: "Chuanhuang Li" To: "Wang,Weiming" , "Jamal Hadi Salim" , "forces@ietf.org" References: Message-ID: <201108120959077504474@mail.zjgsu.edu.cn> Organization: Zhejiang Gongshang Univercity X-mailer: Foxmail 6, 15, 201, 23 [cn] Mime-Version: 1.0 Content-Type: text/plain; charset="gb2312" Content-Transfer-Encoding: 7bit X-CM-TRANSID: rBCI85D74C1zh0ROgI1bAA--.33373S2 X-Coremail-Antispam: 1Uf129KBjDUn29KB7ZKAUJUUUUUYxn0WfASr-VFAUDa7-sFnT 9fnUUIcSsGvfJ3UbIYCTnIWIevJa73UjIFyTuYvj4RJUUUUUUUU X-CM-SenderInfo: pfkxt0xkxd0wxbolqzhdloh6pmjv3hxhgxhubq/ Cc: "Joel M.

So the text i sent earlier can be the following instead. iv) change last paragraph to: " This LFB participates in ethernet flow control in cooperation with EtherMACOut LFB. This document does not go into the details of how this is implemented; the reader may refer to [someIEEE reference]. This document also does not describe how the buffers which induce the flow control messages behave - it is assumed that such artifacts exist and describing them is out of scope in this document". Repeat similar text EtherMACOut etc. I am assuming everything else i posted is ok and the authors are working to update the document.

Continuation of comments: 0) Please check doc for consistency. At times you refer to this LFB as EtherEncapsulator - it should really be EtherEncap. i) "This LFB abstracts the process to encapsulate IP packets to Ethernet packets according to the L2 information" to: "This LFB abstracts the process of encapsulating ethernet headers onto received packets. The encapsulation is based on passed metadata." ii) "The LFB is expected to receive types of IP packets, including IPv4 and IPv6 types" to: "The LFB is expected to receive IPv4 and IPv6 packets" iii) "Optinally an input packet may be accompanied by a Vlan priority metadata. In this case, default value for the metadata is 0." to: "In the case an input packet contains only a Vlan priority field metadata, a default vlan tag of 0 is assumed" Question: Dont we already have a Vlan tag of 0 by the time the packet is passed here? Also, where does this priority vlan field gets set? I dont recall seeing it being produced at any LFB earlier. iv)This is one of those general comments I made that we dont say what the lookup keys are etc: "Upon a successful table lookup," to: "The EncapTable is looked up using the MediaEncapInfoIndex. Upon a successful table lookup, ..." v) Referring to the above - how do i know by looking at the XML that MediaEncapInfoIndex is the index used for the encaptable? Should there be at minimal some synopsis description somewhere that tells me this? vi) It makes sense to say what the ExceptionID that is passed is downstream is known as - I am a little confused as to what the text is referring to. vii) This text was very confusing: "The upstream LFB may be programmed by the CE to pass along a MediaEncapInfoIndex that does not exist in the EncapTable. That is to allow for resolution of the L2 headers, if needed, to be made at the L2 encapsulation level in this case(ethernet) via ARP, or ND (or other methods depending on the link layer technology) when a table miss occurs." change to: "In case of a table miss, i.e. the MediaEncapInfoIndex does not exist in the EncapTable, an exception is generated to be used by the downstream LFBs. This exception could allow for resolution of the L2 headers, if needed, to be made at a downstream LFB via ARP, or ND (or other methods depending on the link layer technology). Refer to section blah blah which describes the different techniques ARP could be implemented." And for that reason, please remove the next paragraph and integrate it into section 7 - where you should talk about both the CE and inline ways (as described above) to do ARP/ND. --- more comments after i get ACKs to these two emails. cheers, jamal From chuanhuang_li@mail.zjgsu.edu.cn Fri Aug 12 07:52:39 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 95D4D21F86D0 for ; Fri, 12 Aug 2011 07:52:39 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.949 X-Spam-Level: X-Spam-Status: No, score=-1.949 tagged_above=-999 required=5 tests=[AWL=0.650, BAYES_00=-2.599] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id Qq09Y6-qS1TY for ; Fri, 12 Aug 2011 07:52:39 -0700 (PDT) Received: from mail.zjgsu.edu.cn (ucmail.zjgsu.edu.cn [124.160.64.1]) by ietfa.amsl.com (Postfix) with SMTP id 39DEC21F86B1 for ; Fri, 12 Aug 2011 07:52:37 -0700 (PDT) Received: from RobinLee (unknown [10.20.0.167]) by mailportal (Coremail) with SMTP id rBCI85CLdDSfPUVOgI1bAA--.34695S2; Fri, 12 Aug 2011 22:50:07 +0800 (CST) Date: Fri, 12 Aug 2011 22:55:35 +0800 From: "Chuanhuang Li" To: "Jamal Hadi Salim" , "forces" Message-ID: <201108122255351563601@mail.zjgsu.edu.cn> Organization: Zhejiang Gongshang Univercity X-mailer: Foxmail 6, 15, 201, 23 [cn] Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-CM-TRANSID: rBCI85CLdDSfPUVOgI1bAA--.34695S2 X-Coremail-Antispam: 1Uf129KBjDUn29KB7ZKAUJUUUUUYxn0WfASr-VFAUDa7-sFnT 9fnUUIcSsGvfJ3UbIYCTnIWIevJa73UjIFyTuYvj4RJUUUUUUUU X-CM-SenderInfo: pfkxt0xkxd0wxbolqzhdloh6pmjv3hxhgxhubq/ Cc: "Joel M.

When the original packet had a VLAN tag, the VlanID would be zero or non-zero. If VlanID was zero, the VlanPriority would be non-zero. When the packet hadn't VLAN tag, the output metadatas VlanID and VlanPriority should all be zero. >13) 5.1.3.2 >i) typo "strcut" >ii) this section doesnt talk about what the key or index is used to >lookup the table EtherDispatchTable or VLANInputTable. I think it helps >to understand those details >--- There are some indications in the text. I also think hey are obscure and need some modification: EtherDispatchTable: "An EtherDispatchTable array component is defined in the LFB to dispatch every Ethernet packet to the output group according to the logical port ID assigned by the VLANInputTable to the packet and the Ethernet type in the Ethernet packet header." VLANInputTable: "Every input packet is assigned with a new LogicalPortID according to the packet incoming port ID and the VLAN ID. " I have one question about the key. Do we need define the key in the LFB XML file? The following is my understanding: If the table contents are generated by CE, key need not be defined. If they are generated by FE , they need be defined in some cases. In RFC5812: In addition to their subscripts, arrays MAY be declared to have content keys. Such a declaration has several effects: o Any declared key can be used in the ForCES protocol to select a component for operations (for details, see the ForCES protocol [RFC5810]). o In any instance of the array, each declared key MUST be unique within that instance. That is, no two components of an array may have the same values on all the fields that make up a key. So i think the key definition in XML is just for CE to implement search function. And when the table is dispathed by CE, CE needn't perform the search operation on FE.

The only thing that requires such a thing is the LPM; i believe we need to define a content key.

If you want to keep that way fine with me - i did not see it that way when i read the text. >>iv)This is one of those general comments I made that we dont say what >>the lookup keys are etc: >>"Upon a successful table lookup," >>to: >>"The EncapTable is looked up using the MediaEncapInfoIndex. >>Upon a successful table lookup, ..." > > There is some indication in Data Handling section: > "The LFB always expects from upstream > =A0 LFBs the MediaEncapInfoIndex metadata which is used as an index to > =A0 lookup the Encapsulation Table." That is true - but you dont explain the success vs failure path. You seem to be talking about the success path. You should be explicit (i.e "Upon successful lookup ... and in case of failure .."). >>v) Referring to the above - how do i know by looking at the XML >>that MediaEncapInfoIndex is the index used for the encaptable? >>Should there be at minimal some synopsis description somewhere that >>tells me this? > > In current XML definition, all tables havn't the key or index information= s in > the synopsis. Do we need explain these things clearly in XML? I think we need to.

Slighly longer than last one ... --- 17)Section 5.2.1.1 i) "This LFB performs IPv4 validation according to RFC 1812. Then the IPv4 packet will be output to the corresponding port regarding of the validation result, whether the packet is a unicast or a multicast one, an exception has occurred or the validation failed." to: "This LFB performs IPv4 validation according to RFC 1812. The IPv4 packet will be output to the corresponding LFB port the indication whether the packet is unicast, multicast or whether an exception has occurred or the validation failed." ii) The paragraph that starts with: "Note that, as a default provision of RFC 5812, .." I dont think belongs in this section. It is a generic description; probably belongs in earlier sections such as the area where the terms downstream/upstream are being introduced. iii) "Four output ports are defined to output various validation results." to: "Four output LFB ports are defined." iv) Delete the unnecessary sentence that reads: "There is no metadata specifically required to produce at these output ports." v) Should the first 3 exceptions really not be errors? I can understand Router Alert being an exception vi) "Note that, although TTL is checked in this LFB for validity, operations to TTL like TTL decreasing will be made only in a followed forwarding LFB." to: "Note that, although TTL is checked in this LFB for validity, operations like TTL decrement are made the downstream forwarding LFB." vii) "A validate error ID is associated to every failed packet to indicate the reason." to: "An error ID is associated a packet to indicate the failure reason." viii) "Packet with source address equal to 255.255.255.255" was earlier listed as an exception and now is listed as an error. I think it should be an error and not at the exception level. 17)Section 5.2.2 RFC 2460 seems to have been entered as text instead of an xml tag. I know this because it doesnt exist in the reference section. If it was the xml2rfc tool would have caught the missing reference.

It is up to you how you want to reach this - my take on it is: functionally assuming presence of both tag and priority is easier to follow= .

When describing a current LFB, an upstream LFB refers to an LFB which is connected to current LFB via data paths and output data packets to current LFB. A downstream LFB refers to an LFB which is connected to current LFB via data paths and receives data packets output from current LFB. May I suggest: In this section, the terms "upstream LFB" and "downstream LFB" are used. These are used relative to an LFB to an LFB that is being described. An "upstream LFB" is one whose output ports are connected to input ports of the LFB under consideration such that output (typically packets with metadata) can be sent from the "upstream LFB" to the LFB under consideration. Similarly, a "downstream LFB" whose input ports are connected to output ports of the LFB under consideration such that the LFB under consideration can send information to the "downstream LFB". Note that in some rare topologies, an LFB may be both upstream and downstream relative to another LFB.

This index is used to lookup a table (typically media encapsulatation related) further downstream. The CE sets it to a value that is not allocated in downstream LFB tables.

It always expects as input IPv6 unicast packets from one singleton input known as "PktsIn". Then the LFB uses the destination IPv6 address of every packet as index to look up the IPv6 prefix table and generate a hop selector as the matching result.

This generated result is associated to the packet as a metadatum sent to downstream LFBs, and will usually be used in those LFBs as an index to find more next hop information."

Each row of the array contains an IPv6 adrress, a Prefix length, a Hop Selector, an ECMP flag and a Default Route flag. The LFB uses the destination IPv6 address of every input packet as index to look up this table to get a hop selector as the result. The ECMP flag is for the LFB to support ECMP. The default route flag is for the LFB to support a default route and for loose RPF." to: "The IPv6PrefixTable component is defined as an array component of the LFB.

The default route flag is for the LFB to support a default route and for loose RPF as described earlier." Note: there was a typo in the original text "adrress" Note: This LFB serves again as a good example of what i was concerned about earlier. You should describe operations in the data handling section. The components section should only talk about components details. ---- cheers, jamal From hadi@mojatatu.com Tue Aug 16 03:55:17 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 6C87921F8ABE for ; Tue, 16 Aug 2011 03:55:17 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.107 X-Spam-Level: X-Spam-Status: No, score=-102.107 tagged_above=-999 required=5 tests=[AWL=-0.330, BAYES_00=-2.599, FM_FORGED_GMAIL=0.622, J_CHICKENPOX_16=0.6, J_CHICKENPOX_37=0.6, RCVD_IN_DNSWL_LOW=-1, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 5dWwNTiNEMoI for ; Tue, 16 Aug 2011 03:55:17 -0700 (PDT) Received: from mail-fx0-f44.google.com (mail-fx0-f44.google.com [209.85.161.44]) by ietfa.amsl.com (Postfix) with ESMTP id AE5DC21F8AA8 for ; Tue, 16 Aug 2011 03:55:16 -0700 (PDT) Received: by fxe6 with SMTP id 6so4564063fxe.31 for ; Tue, 16 Aug 2011 03:56:04 -0700 (PDT) Received: by 10.223.156.72 with SMTP id v8mr7028359faw.87.1313492164182; Tue, 16 Aug 2011 03:56:04 -0700 (PDT) MIME-Version: 1.0 Received: by 10.223.155.199 with HTTP; Tue, 16 Aug 2011 03:55:43 -0700 (PDT) From: Jamal Hadi Salim Date: Tue, 16 Aug 2011 06:55:43 -0400 Message-ID: To: forces@ietf.org Content-Type: text/plain; charset=windows-1252 Content-Transfer-Encoding: quoted-printable Cc: Chuanhuang Li , "Joel M.

(If a downstream LFB lookup fails to find it, it indicates some other way to resolve it may be needed.)" to: "In some cases, depending on implementation, the CE may set the MediaEncapInfoIndex passed downstream to a value that will fail lookup when it gets to a target encapsulation LFB; such a lookup failure at that point is an indication that further resolution is needed. For a discussion on how such an approach could be used refer to section XXX which describes the IPv4NextHop LFB." 41) 5.4.1.1 "RedirectIn LFB is defined with only one output, while without any input." to: "RedirectIn LFB is defined with a single output LFB port (and no input LFB port" XXX: should that be "output LFB port group"? Later on you seem to indicate that =92RedirectIndex=92 is used to select output LFB port. 42) 5.4.1.1 "The CE may associate some metadata to indicate the frame types and may also associate other metadata to indicate various information on the packets." I think that first "may" should be "must". 43) 5.4.1.1 "All metadata from the CE other than the =92RedirectIndex=92 metadata will output from the RedirectIn LFB along with their binding packets." to: "Any other metadata, in addition to =92RedirectIndex=92, will be passed unt= ouched along the packet delivered by the CE." 44)5.4.2.1 "the RedirectOut LFB is defined with only one input, while without any output." to: "RedirectOut LFB is defined with a single input LFB port (and no output LFB port" 45)5.4.2.1 technical question dont we have something equivalent to =92RedirectIndex=92 that the CE can use to deduce source LFBs etc for the purpose of maybe multiplexing when it receives the redirected packet? -------- cheers, jamal From wmwang2001@hotmail.com Tue Aug 16 05:32:50 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 5B29821F8AAC for ; Tue, 16 Aug 2011 05:32:50 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: 0.692 X-Spam-Level: X-Spam-Status: No, score=0.692 tagged_above=-999 required=5 tests=[AWL=-1.062, BAYES_50=0.001, MIME_BASE64_TEXT=1.753] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id uZsCf1cbQ8Uw for ; Tue, 16 Aug 2011 05:32:50 -0700 (PDT) Received: from blu0-omc2-s35.blu0.hotmail.com (blu0-omc2-s35.blu0.hotmail.com [65.55.111.110]) by ietfa.amsl.com (Postfix) with ESMTP id D75B821F8A97 for ; Tue, 16 Aug 2011 05:32:49 -0700 (PDT) Received: from BLU0-SMTP220 ([65.55.111.72]) by blu0-omc2-s35.blu0.hotmail.com with Microsoft SMTPSVC(6.0.3790.4675); Tue, 16 Aug 2011 05:33:38 -0700 X-Originating-IP: [122.235.157.70] X-Originating-Email: [wmwang2001@hotmail.com] Message-ID: Received: from WmwangHome ([122.235.157.70]) by BLU0-SMTP220.phx.gbl over TLS secured channel with Microsoft SMTPSVC(6.0.3790.4675); Tue, 16 Aug 2011 05:33:36 -0700 From: "Wang,Weiming" To: "Jamal Hadi Salim" , References: Date: Tue, 16 Aug 2011 20:33:57 +0800 MIME-Version: 1.0 Content-Type: text/plain; charset="ISO-8859-1" Content-Transfer-Encoding: base64 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2900.5931 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.6109 X-OriginalArrivalTime: 16 Aug 2011 12:33:36.0710 (UTC) FILETIME=[B83C6660:01CC5C10] Cc: "Joel M.

MediaEncapInfoIndex will be used in media encapsulation LFB, such as EtherEncap.

But it need specify where "VlanPriority" metadata is produced and consumed both in EtherClassifier and EtherEncap. It also need point out emphatically this metadata is "optional". When there is no VLAN tag in the orginal packet, EtherClassifier will not produce it, and EtherEncap will not expect it.

You already have similar text in the last paragraph of that section. I was talking about where metadata was created not where it is to be consum= ed.

Here is my last comment on section 5. ---- 46)5.5.1.1. What is the index used to do the table lookup? What happens on failure? I am begining to wonder whether we should have sections describing what metadata each LFB expects, what it consumes and what it creates for consumption further downstream. "...along with a metadata that will be used by the LFB to do the dispatch. If a packet is not associated with such a metadata, the packet will be dropped inside the LFB." What is the name of this metadata? change to: "...along with metadata metadataname that will be used by the LFB to do the dispatch. If an arriving packet has no metadataname associated with it, the packet is dropped by the LFB" 47) 5.5.1.1. "A packet, if it is associated with a metadata with the metadata ID, will be output to the group port instance with the index corresponding to the metadata value in the Metadata Dispatch table." to: " The associated metadataname is used as an index to look up the Metadata Dispatch table. On a successful match, the lookup result defines an LFB port to a downstream LFB. On a failure to look up the Metadata Dispatch table, the packet is dropped." 48) 5.5.1.1. I did not understand this: "Currently the BasicMetadataDispatch only allows an interger value for the metadata to be used for dispatch." Also did not understand: "The BasicMetadataDispatch LFB is currently defined with only one metadata adopted for dispatch, i.e., the metadata ID in the dispatch table is always the same for all table rows." Is there only one entry in this table? 49) 5.5.1.2. typo "selectt" 50) 5.5.2.1. ".. with every input port instance connected to one queue" to: ".. with every input LFB port instance connected to one queue" 51) 5.5.2.1. I understand that each input LFB port instance is connected to one queue but there are no examples of what the upstream LFB could be anywhere in the document. Or downstream for that matter. Figure1 doesnt show schedulers - could we have 2-3 sentences describing examples? 51) 5.5.2.1. Dont wanna spend too much time on this, RR is fine - but isnt priority based queueing the scheme defined as a basic scheduler? In the case of IPV4 Tos/DSCP etc (RFC 1812?) is used to select the queue. 52) 5.5.2.3. "The supported scheduling disciplines types by the FE, currently maximum 6." Where did the magic number 6 come from? ---- cheers, jamal From jmh@joelhalpern.com Wed Aug 17 07:29:53 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 9386B21F8B34 for ; Wed, 17 Aug 2011 07:29:53 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -101.661 X-Spam-Level: X-Spam-Status: No, score=-101.661 tagged_above=-999 required=5 tests=[AWL=-0.862, BAYES_00=-2.599, J_CHICKENPOX_25=0.6, J_CHICKENPOX_64=0.6, J_CHICKENPOX_83=0.6, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id mxDzrhr-9CBa for ; Wed, 17 Aug 2011 07:29:53 -0700 (PDT) Received: from hgblob.out.tigertech.net (hgblob-ipv6.tigertech.net [IPv6:2604:4f00::1:0:0:22]) by ietfa.amsl.com (Postfix) with ESMTP id 2E78821F8B2F for ; Wed, 17 Aug 2011 07:29:53 -0700 (PDT) Received: from localhost (localhost [127.0.0.1]) by hgblob.tigertech.net (Postfix) with ESMTP id 83AD7325C155; Wed, 17 Aug 2011 07:30:43 -0700 (PDT) X-Virus-Scanned: Debian amavisd-new at hgblob.tigertech.net Received: from [10.10.10.105] (pool-71-161-51-177.clppva.btas.verizon.net [71.161.51.177]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (No client certificate requested) by hgblob.tigertech.net (Postfix) with ESMTPSA id 57D15325C158; Wed, 17 Aug 2011 07:30:42 -0700 (PDT) Message-ID: <4E4BD08E.1020303@joelhalpern.com> Date: Wed, 17 Aug 2011 10:30:38 -0400 From: "Joel M.

One of the reasons for including certain metadata items we have included was specifically so that any processing, including the CE, could trace back as much as it needed. I have assumed that there was enough for the CE to figure out all error cases. I would not add a generic metadatum, as I don't think we know how it would be filled in. But if there is a case where we are missing some information, we should add that.

As an example, a packet could be redirected by the FE to the CE because the EtherEncap LFB is not able to resolve L2 information. The metadata "ExceptionID", created by the EtherEncap LFB is passed along with the packet and should be sufficient for the CE to do the necessary processing and resolve the L2 entry required. cheers, jamal From hadi@mojatatu.com Sun Aug 21 07:24:06 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 8579221F8A7E for ; Sun, 21 Aug 2011 07:24:06 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.662 X-Spam-Level: X-Spam-Status: No, score=-102.662 tagged_above=-999 required=5 tests=[AWL=0.315, BAYES_00=-2.599, FM_FORGED_GMAIL=0.622, RCVD_IN_DNSWL_LOW=-1, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id Q8QO7H94fS+h for ; Sun, 21 Aug 2011 07:24:05 -0700 (PDT) Received: from mail-fx0-f44.google.com (mail-fx0-f44.google.com [209.85.161.44]) by ietfa.amsl.com (Postfix) with ESMTP id 6B72A21F8A58 for ; Sun, 21 Aug 2011 07:24:05 -0700 (PDT) Received: by fxe6 with SMTP id 6so3106440fxe.31 for ; Sun, 21 Aug 2011 07:25:06 -0700 (PDT) Received: by 10.223.97.210 with SMTP id m18mr2164340fan.127.1313936706153; Sun, 21 Aug 2011 07:25:06 -0700 (PDT) MIME-Version: 1.0 Received: by 10.223.108.1 with HTTP; Sun, 21 Aug 2011 07:24:45 -0700 (PDT) From: Jamal Hadi Salim Date: Sun, 21 Aug 2011 10:24:45 -0400 Message-ID: To: forces@ietf.org Content-Type: text/plain; charset=ISO-8859-1 Cc: Chuanhuang Li , "Joel M.

The functions demonstrated are: o IPv4 forwarding o ARP processing It is assumed the LFB topology on the FE described has already been established by the CE and maps to the use cases illustrated in this section. The use cases demonstrated in this section are mere examples and by no means should be treated as the only way one would construct router functionality from LFBs; based on the capability of the FE(s), a CE should be able to express different NE applications. ------- cheers, jamal From hadi@mojatatu.com Sun Aug 21 07:26:20 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 1E32D21F8AA9 for ; Sun, 21 Aug 2011 07:26:20 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -101.471 X-Spam-Level: X-Spam-Status: No, score=-101.471 tagged_above=-999 required=5 tests=[AWL=-0.894, BAYES_00=-2.599, FM_FORGED_GMAIL=0.622, J_CHICKENPOX_16=0.6, J_CHICKENPOX_37=0.6, J_CHICKENPOX_38=0.6, J_CHICKENPOX_39=0.6, RCVD_IN_DNSWL_LOW=-1, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 3ybNGpt9QSef for ; Sun, 21 Aug 2011 07:26:19 -0700 (PDT) Received: from mail-fx0-f44.google.com (mail-fx0-f44.google.com [209.85.161.44]) by ietfa.amsl.com (Postfix) with ESMTP id 688A721F8A91 for ; Sun, 21 Aug 2011 07:26:19 -0700 (PDT) Received: by fxe6 with SMTP id 6so3107246fxe.31 for ; Sun, 21 Aug 2011 07:27:21 -0700 (PDT) Received: by 10.223.29.76 with SMTP id p12mr2027045fac.51.1313936841180; Sun, 21 Aug 2011 07:27:21 -0700 (PDT) MIME-Version: 1.0 Received: by 10.223.108.1 with HTTP; Sun, 21 Aug 2011 07:27:01 -0700 (PDT) From: Jamal Hadi Salim Date: Sun, 21 Aug 2011 10:27:01 -0400 Message-ID: To: forces@ietf.org Content-Type: text/plain; charset=ISO-8859-1 Cc: Chuanhuang Li , "Joel M.

A number of EtherPHYCop LFB(section XXX) instances are used to describe physical layer functions of the ports. PHYPortID metadatum is generated by EtherPHYCop LFB and is used by all the subsequent downstream LFBs. An EtherMACIn LFB(section XXX), which describe the MAC layer processing, follows every EtherPHYCop LFB. The EtherMACIn LFB may do a locality check of MAC addresses if the CE configures the appropriate EtherMACIn LFB component. Ethernet packets out of the EtherMACIn LFB are sent to an EtherClassifier LFB (section XXX) to be decapsulated and classified into network layer types like IPv4, IPv6, ARP, etc. In the example use case, every physical Ethernet interface is associated with one Classifier instance; although not illustrated, it is also feasible that all physical interfaces are associated with only one Ethernet Classifier instance. EtherClassifier uses the PHYPortID metadatum, the Ethernet type of the input packet, and VlanID (if present in the input Ethernet packets), to decide the packet network layer type and the LFB output port to the downstream LFB. The EtherClassifier LFB also assigns a new logical port ID metadata to the packet for later use. The EtherClassifier may also generate some new metadata for every packet like EtherType, SrcMAC, DstMAC, LogicPortID, etc for consumption by downstream LFBs. If a packet is classified as an IPv4 packet, it is sent downstream to an IPv4Validator LFB(section XXX) to validate the IPv4 packet. In the validator LFB, IPv4 packets are validated and are additionally classified into either IPv4 unicast packets and multicast packets. IPv4 unicast packets are sent to downstream to the IPv4UcastLPM LFB(section XXX). The IPv4UcastLPM LFB is where the longest prefix match decision is made, and a next hop selection is selected. The nexthop ID metadata is generated by the IPv4UcastLPM LFB to be consumed downstream by the IPv4NextHop LFB(section XXX). The IPv4NextHop LFB uses the nexthop ID metadata to do derive where the packet is to go next and the media encapsulation type for the port, etc. The IPv4NextHop LFB generates the L3PortID metadata used to identify a next hop output physical/logical port. In the example use case, the next hop output port is an Ethernet type; as a result, the packet and its L3 port ID metadatum are sent downstream to an EtherEncap LFB(section XXX). The EtherEncap LFB encapsulates the incoming packet into an Ethernet frame. A BasicMetadataDispatch LFB (section XXX) follows the EtherEncap LFB. The BasicMetadataDispatch LFB is where packets are finally dispatched to different output physical/logical ports abased on the L3PortID metadatum sent to the LFB. ------ cheers, jamal From hadi@mojatatu.com Sun Aug 21 07:33:44 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 48C5D21F8A4E for ; Sun, 21 Aug 2011 07:33:44 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.046 X-Spam-Level: X-Spam-Status: No, score=-102.046 tagged_above=-999 required=5 tests=[AWL=-0.269, BAYES_00=-2.599, FM_FORGED_GMAIL=0.622, J_CHICKENPOX_16=0.6, J_CHICKENPOX_37=0.6, RCVD_IN_DNSWL_LOW=-1, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id dDgpTHkVGYFo for ; Sun, 21 Aug 2011 07:33:43 -0700 (PDT) Received: from mail-fx0-f44.google.com (mail-fx0-f44.google.com [209.85.161.44]) by ietfa.amsl.com (Postfix) with ESMTP id A0EF721F8A23 for ; Sun, 21 Aug 2011 07:33:43 -0700 (PDT) Received: by fxe6 with SMTP id 6so3109599fxe.31 for ; Sun, 21 Aug 2011 07:34:45 -0700 (PDT) Received: by 10.223.6.91 with SMTP id 27mr2134104fay.146.1313937285354; Sun, 21 Aug 2011 07:34:45 -0700 (PDT) MIME-Version: 1.0 Received: by 10.223.108.1 with HTTP; Sun, 21 Aug 2011 07:34:20 -0700 (PDT) From: Jamal Hadi Salim Date: Sun, 21 Aug 2011 10:34:20 -0400 Message-ID: To: forces@ietf.org Content-Type: text/plain; charset=ISO-8859-1 Cc: Chuanhuang Li , "Joel M.

By no means is this the only way ARP processing could be achieved; as an example ARP processing could happen at the FE - but that discussion is out of scope for this use case. There are two ways ARP processing could be triggered in the CE as illustrated in figure 2: o ARP packets arriving from outside of the NE o IPV4 packets failing to resolve within the FE ARP packets from network interfaces are filtered out by EtherClassifier LFB. The classified ARP packets and associated metadata are then sent downstream to the RedirectOut LFB(section XXX) to be transported to CE. The EtherEncap LFB, as described earlier, receives packets that need Ethernet L2 encapsulating. When the EtherEncap LFB fails to find the necessary L2 Ethernet information to encapsulate the packet with, it outputs the packet to its ExceptionOut LFB port. Downstream to EtherEncap LFB's ExceptionOut LFB port is the RedirectOut LFB which transports the packet to the CE (see Section XXX for details). To achieve its goal, the CE needs to generate ARP request and response packets and send them to external (to the NE) networks. ARP request and response packets from the CE are redirected to an FE via a RedirectIn LFB(section XXX). As was the case with forwarded IPv4 packets, outgoing ARP packets are also encapsulated to Ethernet format by the EtherEncap LFB, and then dispatched to different interfaces via a BasicMetadataDispatch LFB. The BasicMetadataDispatch LFB dispatches the packets according to the L3PortID metadatum included in every ARP packet sent from CE. ---- cheers, jamal From chuanhuang_li@mail.zjgsu.edu.cn Sun Aug 21 23:09:07 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 60AE321F86B1 for ; Sun, 21 Aug 2011 23:09:07 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: 1.078 X-Spam-Level: * X-Spam-Status: No, score=1.078 tagged_above=-999 required=5 tests=[AWL=-1.176, BAYES_20=-0.74, J_CHICKENPOX_37=0.6, J_CHICKENPOX_55=0.6, MIME_BASE64_BLANKS=0.041, MIME_BASE64_TEXT=1.753] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id XGgsYOt0U+to for ; Sun, 21 Aug 2011 23:09:06 -0700 (PDT) Received: from mail.zjgsu.edu.cn (ucmail.zjgsu.edu.cn [124.160.64.1]) by ietfa.amsl.com (Postfix) with SMTP id 05D8D21F8661 for ; Sun, 21 Aug 2011 23:09:04 -0700 (PDT) Received: from RobinLee (unknown [10.20.0.167]) by mailportal (Coremail) with SMTP id rBCI85BrpzbK8VFOgI1bAA--.65237S2; Mon, 22 Aug 2011 14:06:02 +0800 (CST) Date: Mon, 22 Aug 2011 14:10:40 +0800 From: "Chuanhuang Li" To: "Jamal Hadi Salim" References: <201108122255351563601@mail.zjgsu.edu.cn>, , <201108171102177183945@mail.zjgsu.edu.cn>, <201108181015224373066@mail.zjgsu.edu.cn> Message-ID: <201108221410402968991@mail.zjgsu.edu.cn> Organization: Zhejiang Gongshang Univercity X-mailer: Foxmail 6, 15, 201, 23 [cn] Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: base64 X-CM-TRANSID: rBCI85BrpzbK8VFOgI1bAA--.65237S2 X-Coremail-Antispam: 1Uf129KBjDUn29KB7ZKAUJUUUUUYxn0WfASr-VFAUDa7-sFnT 9fnUUIcSsGvfJ3UbIYCTnIWIevJa73UjIFyTuYvj4RJUUUUUUUU X-CM-SenderInfo: pfkxt0xkxd0wxbolqzhdloh6pmjv3hxhgxhubq/ Cc: forces , "Joel M.

The "index" is the position in the array, usable with the index reference form. It is not a field in the array contents. In contrast, array entry information which can be used for lookups is key information.

This "index" is not a member of the table = structure. Indeed this is the index i was referring to, and as Joel said your understa= nding is correct. It is not part of the row content rather it is a position of where the content is. 1) The CE knows such an index because it created it or it queried the FE about it; and can coordinate upstream LFBs to have it as an entry in their table content, example: LogicalPortID in upstream EtherDispatchTable of EtherClassifier LFB. 2) LogicalPortID arrives as metadata at a downstream LFB where is to be used to index/lookup some (downstream) table. I am concerned about #2. The text is highly lacking to describe what metadata is used as an index for the table. We need to say it clearly in the text for each table. something like: "Metadata LogicalPortID is used as table index for table bl= ah". The text for example does a good job to describe that IPv4Address is used as the content key for the IPv4PrefixTable. i.e the extra description would be of the form: "Table Foo: Table index, goo metadata" Does this make sense? On the difference between keys and indices in our terminology: A key is derived from content and the CE has no control over its value (IPV4 address on arriving packet). Table index is configured by the CE. Index lookup is typical O(1). Content Key lookup is much more expensive. cheers, jamal From internet-drafts@ietf.org Wed Aug 24 10:39:17 2011 Return-Path: X-Original-To: forces@ietfa.amsl.com Delivered-To: forces@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 388CF21F8BEF; Wed, 24 Aug 2011 10:39:17 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.599 X-Spam-Level: X-Spam-Status: No, score=-102.599 tagged_above=-999 required=5 tests=[AWL=0.000, BAYES_00=-2.599, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id ocq9OU2pDCJf; Wed, 24 Aug 2011 10:39:16 -0700 (PDT) Received: from ietfa.amsl.com (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id D3C5121F8B2A; Wed, 24 Aug 2011 10:39:16 -0700 (PDT) MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable From: internet-drafts@ietf.org To: i-d-announce@ietf.org X-Test-IDTracker: no X-IETF-IDTracker: 3.59 Message-ID: <20110824173916.13143.44143.idtracker@ietfa.amsl.com> Date: Wed, 24 Aug 2011 10:39:16 -0700 Cc: forces@ietf.org Subject: [forces] I-D Action: draft-ietf-forces-ceha-02.txt X-BeenThere: forces@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: ForCES WG mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 24 Aug 2011 17:39:17 -0000 A New Internet-Draft is available from the on-line Internet-Drafts director= ies.
