In draft-tissa-lime-yang-oam-mo= del-05, there are two ways to represent referencing interface in the ietf-i= nterfaces module:

Representation A:

     &= nbsp;          leaf interface = {

     &= nbsp;           &nbs= p; type if:interface-ref;

     &= nbsp;            des= cription

     &= nbsp;            &qu= ot;Interface name as defined by ietf-interfaces";

     &= nbsp;          }

Representation B:

     &= nbsp;          leaf interface = {

     &= nbsp;            typ= e leafref {

     &= nbsp;           &nbs= p;  path "/if:interfaces/if:interface/if:name";

     &= nbsp;            }

     &= nbsp;            des= cription

     &= nbsp;           &nbs= p;  "Outgoing Interface";

 

For consistency, we should choo= se one of them. I believe we should use representation A since interface be= ing referenced is defined in other document.

Personally I would prefer option A, as this does not require any knowledge about the paths used in ietf-interfaces.

But I have two comments when reading it. In draft-wang-lime-yang-pm-00, loss measurement is supported. Hence, I am w= ondering if the loss-repsonder parameter can be enabled to support syntheti= c loss measurement. In addition, single ended responder is supported, can I assume dual-ended r= esponder can also be supported as well? Many thanks.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 24 Jun 2015 06:55:10 -0000 Hi all, The authors of draft-tissa-lime-yang-oam-model asked for comments to the authors of draft-lam-lime-summary-l0-l2-layer-independent. So far, I, as a co-author of draft-lam..., have collected comments among us and here are attached the comments as below. I hope the comments will contribute the progress of draft-tissa-lime-yang-oam-model. Regards, Yuji ------ Comments 1. Common OAM architecture This document defines the relationship of different OAM YANG model that covers MPLS, IP, NVO3, TRILL and so on. But there seems to be no Common OAM architecture for them, but the common OAM architecture in this draft adapts those for Ethernet (IEEE802.1Q and ITU-T G.8013/Y.1731) or MPLS-TP (RFC 6371). Given that this draft covers only Ethernet and MPLS-TP OAM, it would not have any issues. But how about other technologies like IP or (IP/)MPLS? Do they use the architecture same as Ethernet or MPLS-TP? 2. Common tools for OAM The current draft only describes based on Ethernet CCM so that all the parameters in the draft come basically from those for configuring MEPs of Ethernet (and some for IPv4 and IPv6). For the definition of Generic OAM, it is required to describe what kind of the tool sets are considered in this draft. The good example is in Table 7-1 of ITU-T G.8113.2. 3. Configuration data structure for MEP (section 4.3) Reading MEP in ietf-gen-oam, the MEP is regarded as bidirectional end point that includes both generation process and reception process. ITU-T G.8052 (or ONF work for OAM) defines MEP that includes generation process and reception process (i.e. Source and Sink). In fact, Ethernet CCM works as one-way (called Dual-ended) so that the clear distinction for MEP source and sink is defined in G.8052. This draft should be consider MEP source and sink. Also co-located sink MEP in case of a bi-directional connection should be considered. 4. Output in rpcs Output in rpcs includes performance monitoring (i.e Delay measurement, Loss measurement)related configuration data, But it looks as a part of CC and CV functionalities. As seen in ITU-T G.8013 (DM, LM, and Synthetic LM) and PM for Trill OAM, the output (PM related configuration data) should be regarded in more generic way. BTW, the YANG for the output says: output { uses monitor-stats { description "Stats of continuity check is same as that of monitor sessions"; } } } What does mean by "Stats of continuity check is same as that of monitor sessions"? 5. Defect type It describes as: notifications: +---n defect-condition-notification +--ro technology identityref : +--ro defect-type? identityref The authors are interested in what kind of types are in for defect-type. In general, like section 4.4 (rpc), it is expected that the detailed/clarified section for notification is added. 6. Comments on Introduction (Section 1) Three comments: (1) Three bullets should be updated as: 1. monitor networks --> 1. monitor connections 2. isolation --> localization 3. measure performance --> 3. monitor performance (loss, delay). (2) "The YANG data model presented in this document occurs at the management layer." should this be: "The YANG data model presented in this document exists at themanagement layer." (3) The sentence in the last paragraph "This ability to go up and down to different layers" is not a good description for "nesting". 7. Comment on Terminology (Section 2.1) Since the model is based on IEEE802.1Q, the expansion for MEP and MIP should follow IEEE802.1Q. 8. Comments on Overview of the OAM Model (Section 4) Three comments: (1) What is a "parallel vertical"? (2) What is "rpc"? (expansion is missing) And note that both rpc and RPC is used throughout the draft. (3) The sentence "Under each MA, there can be two or more MEPs "implies that the two MEPs are the source and sink of a connection, Does this mean that for a bi-directional (transport) connection there are two MAs? 9. Comment on OAM data hierarchy (Section 4.5) It is suggested to move the first part (from: The following notations" until "leafs and leaf-lists ") to the front of section 4, because the notation is also used in sections 4.1... 4.4. ------ From nobody Wed Jun 24 22:24:40 2015 Return-Path: X-Original-To: lime@ietfa.amsl.com Delivered-To: lime@ietfa.amsl.com Received: from localhost (ietfa.amsl.com [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 90C051B2F3E for ; Wed, 24 Jun 2015 22:24:38 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.099 X-Spam-Level: X-Spam-Status: No, score=-1.099 tagged_above=-999 required=5 tests=[BAYES_00=-1.9, DKIM_SIGNED=0.1, DKIM_VALID=-0.1, DKIM_VALID_AU=-0.1, FREEMAIL_FROM=0.001, HTML_MESSAGE=0.001, J_CHICKENPOX_71=0.6, MIME_8BIT_HEADER=0.3, SPF_PASS=-0.001] autolearn=no Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id Z_nW8XU05bfU for ; Wed, 24 Jun 2015 22:24:36 -0700 (PDT) Received: from mail-pd0-x233.google.com (mail-pd0-x233.google.com [IPv6:2607:f8b0:400e:c02::233]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) by ietfa.amsl.com (Postfix) with ESMTPS id 8C3281B2F68 for ; Wed, 24 Jun 2015 22:24:23 -0700 (PDT) Received: by pdcu2 with SMTP id u2so45605017pdc.3 for ; Wed, 24 Jun 2015 22:24:23 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=date:from:to:cc:message-id:in-reply-to:references:subject :mime-version:content-type; bh=sXoKG3qkeN1DO4gCqMUjIGrNdO0+TTba2zP2tz2BNVw=; b=eeV8AV9XDrARUDqKLMSt97/M7EFzOmV4LRpOQc6tgZFVgpWBzFbutOh/5L1P7V3toz k8nEhZkDurIM5HdTEUC78HTb+GjD/PkbZHSX6Nf3E3HoL9nE+ChKBmI8ljidyXhL6Wiw Wvn2yCl9qrQsndIDeKv4WgPbbhRoEOQm9Rn3pifOe2+5QxEnDVJiA2y1VEKEAvSvmmQo s5BhQKMCaP32avCzRL5F2PBoD98xw/mzfo6kxGIkFcg891hBEyIEXWbUjL1XrZXZMRk8 gJNlkWZJnPf0hjCWm/RYsQzsuLqmzYnctFGvM6tfqtaz71w6qsTbFodFXhQHWnZu8vsa YPXg== X-Received: by 10.66.155.197 with SMTP id vy5mr88172378pab.104.1435209863172; Wed, 24 Jun 2015 22:24:23 -0700 (PDT) Received: from [10.32.178.185] ([182.92.253.16]) by mx.google.com with ESMTPSA id fk5sm24008653pab.40.2015.06.24.22.24.20 (version=TLSv1 cipher=RC4-SHA bits=128/128); Wed, 24 Jun 2015 22:24:22 -0700 (PDT) Date: Thu, 25 Jun 2015 13:24:17 +0800 From: Dapeng Liu To: Qin Wu Message-ID: <0258F326EF0E44B88070D179BB28DE45@gmail.com> In-Reply-To: References: X-Mailer: sparrow 1.6.4 (build 1176) MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="558b9081_354fe9f9_118" Archived-At: Cc: "=?utf-8?Q?lime=40ietf.org?=" , Deepak Kumar Subject: [Lime] =?utf-8?Q?=E5=9B=9E=E5=A4=8D=EF=BC=9A_?= New Version Notification for draft-tissa-lime-yang-oam-model-05.txt X-BeenThere: lime@ietf.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: "Layer Independent OAM Management in Multi-Layer Environment \(LIME\) discussion list."

All,

Some additional remarks on draft-tissa-lime-yang-oam-model-05

In the introduction section:
1.  monitor networks --> 1. monitor connections
this because actually the connections in the network are monitored.

2. isolation --> localisation
it is not always possible to isolate a fault, but if one can locate it
one can take proper consequent actions (like isolation)

3. measure performance --> 3. monitor performance (loss, delay).
monitor implies that consequent actions may/will be taken/

Proper expansion of MEP (from 802.1):

3.93 Maintenance association End Point (MEP)

Proper expansion of MIP (from 802.1Q):

3.98 Maintenance domain Intermediate Point (MIP)

Best regards, Huub.

BTW: the latter two remarks are also applicable to
draft-tissa-nvo3-oam-fm-02 IEEE Std 802.1Q™-2011, IEEE Standard for Local and metropolitan area networks—Media Access Control (MAC) Bridges and Virtual Bridged Local Area Networks

Hi all,

The authors of draft-tissa-lime-yang-oam-model asked for comments to the authors of draft-lam-lime-summary-l0-l2-layer-independent.
So far, I, as a co-author of draft-lam..., have collected comments among us and here are attached the comments as below.

I hope the comments will contribute the progress of draft-tissa-lime-yang-oam-model.


Regards,
Yuji

Comments

1. Common OAM architecture

This document defines the relationship of different OAM YANG model that covers MPLS, IP, NVO3, TRILL and so on. But there seems to be no Common OAM architecture for them, but the common OAM architecture in this draft adapts those for Ethernet (IEEE802.1Q and ITU-T G.8013/Y.1731) or MPLS-TP (RFC 6371).
Given that this draft covers only Ethernet and MPLS-TP OAM, it would not have any issues. But how about other technologies like IP or (IP/)MPLS? Do they use the architecture same as Ethernet or MPLS-TP?


2. Common tools for OAM

The current draft only describes based on Ethernet CCM so that all the parameters in the draft come basically from those for configuring MEPs of Ethernet (and some for IPv4 and IPv6).
For the definition of Generic OAM, it is required to describe what kind of the tool sets are considered in this draft.
The good example is in Table 7-1 of ITU-T G.8113.2.


3. Configuration data structure for MEP (section 4.3)

Reading MEP in ietf-gen-oam, the MEP is regarded as bidirectional end point that includes both generation process and reception process.
ITU-T G.8052 (or ONF work for OAM) defines MEP that includes generation process and reception process (i.e. Source and Sink).
In fact, Ethernet CCM works as one-way (called Dual-ended) so that the clear distinction for MEP source and sink is defined in G.8052.
This draft should be consider MEP source and sink.
Also co-located sink MEP in case of a bi-directional connection should be considered.


4. Output in rpcs
Output in rpcs includes performance monitoring (i.e Delay measurement, Loss measurement)related configuration data, But it looks as a part of CC and CV functionalities.
As seen in ITU-T G.8013 (DM, LM, and Synthetic LM) and PM for Trill OAM, the output (PM related configuration data) should be regarded in more generic way.
BTW, the YANG for the output says:

    output {
      uses monitor-stats {
        description
          "Stats of continuity check is same as that of
           monitor sessions";
      }
    }
  }


What does mean by "Stats of continuity check is same as that of monitor sessions"?


5. Defect type

It describes as:
   notifications:
      +---n defect-condition-notification
         +--ro technology          identityref
:
         +--ro defect-type?        identityref

The authors are interested in what kind of types are in for defect-type.
In general, like section 4.4 (rpc), it is expected that the detailed/clarified section for notification is added.


6. Comments on Introduction (Section 1)

Three comments:

(1) Three bullets should be updated as:
1.  monitor networks --> 1. monitor connections
2. isolation --> localization
3. measure performance --> 3. monitor performance (loss, delay).

(2) "The YANG data model presented in this document occurs at the management layer."
should this be:
"The YANG data model presented in this document exists at themanagement layer."

(3) The sentence in the last paragraph "This ability to go up and down to different layers" is not a good description for "nesting".


7. Comment on Terminology (Section 2.1)

Since the model is based on IEEE802.1Q, the expansion for MEP and MIP should follow IEEE802.1Q.


8. Comments on Overview of the OAM Model (Section 4)

Three comments:

(1) What is a "parallel vertical"?
(2) What is "rpc"? (expansion is missing) And note that both rpc and RPC is used throughout the draft.
(3) The sentence "Under each MA, there can be two or more MEPs "implies that the two MEPs are the source and sink of a connection, Does this mean that for a bi-directional (transport) connection there are two MAs?


9. Comment on OAM data hierarchy (Section 4.5)

It is suggested to move the first part (from:  The following notations" until "leafs and leaf-lists ") to the front of section 4, because the notation is also used in sections 4.1... 4.4.

Hi all,

 

According to deliverables of LI= ME WG, we prepared and submitted a draft to explain the applicability of LI= ME YANG models to existing OAM technologies.<= o:p>

https://datat= racker.ietf.org/doc/draft-zhuang-lime-yang-oam-model-applicability/

 

In general, this draft first pr= ovides common guidelines to extend the LIME base model to generate a model = for a specific OAM technology.

With this, it further demonstra= tes the usability and extensibility of the base model to existing OAM techn= ologies, such as IP OAM, TRILL OAM and so on.

Usage examples are also provide= d for some of them for more detailed explanation.

 

During our documentation, here = are some considerations:

*Performance measurement is not= included in the gen-oam model, but extensions for PM are explained in this= draft to give a whole picture of OAM technology.

*Common extensions are provided= for some OAM technologies, while others are not since some technology-spec= ific models are still being worked on in the respective working groups.

 

As a start point of applicabili= ty work, this draft still has many issues to be discussed and improved.

We appreciate if you can show y= our comments on the proposed draft and discuss with us.

 

Thanks a lot.=

 

Regards,

 

Yan
