In the existing as well as next generation network architectures, there are lot of new services getting added in the service plane with in the network. services here include subscriber aware services, flow based traffic load balancing, content delivery servers, real time streaming applications and similar. The performance of these services are monitored using set of attributes. some of the critical attributes are latency introduced in the packet path, impact on network capacity and throughput. some other attributes are to check whether a service node is alive or not. To Address some of these challenges, how about extending TWAMP protocol (RFC 5357) to monitor service KPIs and monitor the liveliness of the service or application. Today TWAMP is used to measure just RTT between 2 Network Elements, like routers, servers etc. Since Routers are no more just forwarding packets but running lot more services like CGNAT, DPI, IPSec, TDF and like. Even Servers are used to run applications like DNS, HTTP over it. Existing standard protocols cannot measure the impact of enabling service on packets that get routed via a router in terms of latency and the throughput. Similarly they cannot figure out the liveliness of an application on a server even though they can figure out that the server is alive. With the advent of SDN and VNFs, the latency of a VNF would really make lot of sense for the network operator for optimal network planning and deployment. Based on the real time latency, the network operator can possibly spawn more VMs for a services VNF when required and can shut down some of them when not required. We therefore think that adding this new dimension to TWAMP protocol would really be helpful for network monitoring and analysis. We request you all to please share your thoughts on the same. --=20 Thanks and Regards, Vathsa From nobody Mon Jun 8 09:31:27 2015 Return-Path: X-Original-To: ippm@ietfa.amsl.com Delivered-To: ippm@ietfa.amsl.com Received: from localhost (ietfa.amsl.com [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 516041B3048 for ; Mon, 8 Jun 2015 09:31:26 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -0.6 X-Spam-Level: X-Spam-Status: No, score=-0.6 tagged_above=-999 required=5 tests=[BAYES_05=-0.5, DKIM_SIGNED=0.1, DKIM_VALID=-0.1, DKIM_VALID_AU=-0.1, FREEMAIL_FROM=0.001, SPF_PASS=-0.001] autolearn=ham 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 AhT3C-3gpydC for ; Mon, 8 Jun 2015 09:31:23 -0700 (PDT) Received: from mail-ob0-x235.google.com (mail-ob0-x235.google.com [IPv6:2607:f8b0:4003:c01::235]) (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 A32311B304C for ; Mon, 8 Jun 2015 09:31:23 -0700 (PDT) Received: by obbgp2 with SMTP id gp2so79969445obb.2 for ; Mon, 08 Jun 2015 09:31:23 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type:content-transfer-encoding; bh=q+FTmfTarBZM6NvwMWP4PXmk3hSguJy7i7VmA82nIu8=; b=J0NsR1JJMO6x9/GARh3qdq+jRxU/N3+YWNAYh66oqXEDrA1u+JInfUAfNyTAJXkGRO vOUiu9dgEtt+HufKTty11Wl3ciwAjU7I/wJzUXEQXdvh/qp3n2lfmvHgOZ+LMqOiip4h 8yppHH0tWyMhexzTzhP1coL54z1XvantOTA0Qy6t2M822YqbPNKMkJH4bkyrTVqfezmy T2cWthDcDz585a8nM4DGUW3d0vFuUEY0K2UJg8HiEyhBvsGIJAUmMph7cgnFKD64HlIk si2NE3outYjcuDZvyoKhbw55O/n0DVK0SL1kCguw+qFktAe7xiouU3aARswT17uEY4HR 45XA== MIME-Version: 1.0 X-Received: by 10.202.216.138 with SMTP id p132mr14383193oig.133.1433781083123; Mon, 08 Jun 2015 09:31:23 -0700 (PDT) Received: by 10.202.105.129 with HTTP; Mon, 8 Jun 2015 09:31:23 -0700 (PDT) In-Reply-To: References: Date: Mon, 8 Jun 2015 09:31:23 -0700 Message-ID: From: Dave Taht To: Srivathsa Sarangapani Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Archived-At: Cc: "ippm@ietf.org" Subject: Re: [ippm] Discussion on extending TWAMP to monitor service KPIs and detect liveliness of an application X-BeenThere: ippm@ietf.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: IETF IP Performance Metrics Working Group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 08 Jun 2015 16:31:26 -0000 On Mon, Jun 8, 2015 at 9:17 AM, Srivathsa Sarangapani wrote: > Dear IPPM, > > I would like to share something with you today. > > In the existing as well as next generation network architectures, there > are lot of new services getting added in the service plane with in the > network. services here include subscriber aware services, flow based > traffic load balancing, content delivery servers, real time streaming > applications and similar.

I would like to see smokeping more widely used, and bandwidth presented at the same time as loss, ECN CE, and latency in more mtrg and cacti (and o= ther widely used network management system) graphs. While I would like to see more twamp deployments, it is kind of a headache to deploy (ntp time sensitivity for starters - that said, I would also like to see better timekeeping across the internet also). > > Today TWAMP is used to measure just RTT between 2 Network Elements, like > routers, servers etc. > Since Routers are no more just forwarding packets but running lot more > services like CGNAT, DPI, IPSec, TDF and like. > Even Servers are used to run applications like DNS, HTTP over it. > > Existing standard protocols cannot measure the impact of enabling service > on packets that get routed via a router in terms of latency and the > throughput. > Similarly they cannot figure out the liveliness of an application on a > server even though they can figure out that the server is alive.

I would like to see smokeping more widely used, and bandwidth presented at the same time as loss, ECN CE, and latency in more mtrg and cacti (and other widely used network management system) graphs. While I would like to see more twamp deployments, it is kind of a headache to deploy (ntp time sensitivity for starters - that said, I would also like to see better timekeeping across the internet also). Vathsa>>> For RTT calculations the NTP synchronization should not matter. Anyways the PTP(Precision Time Protocol) should provide more precision than NTP which is being deployed of late. For monitoring service KPIs like latency we are always interested in delta and not the actual time stamps. For other service KPIs like load, capacity we are not interested in time at all. > > Today TWAMP is used to measure just RTT between 2 Network Elements, like > routers, servers etc. > Since Routers are no more just forwarding packets but running lot more > services like CGNAT, DPI, IPSec, TDF and like. > Even Servers are used to run applications like DNS, HTTP over it. > > Existing standard protocols cannot measure the impact of enabling service > on packets that get routed via a router in terms of latency and the > throughput. > Similarly they cannot figure out the liveliness of an application on a > server even though they can figure out that the server is alive. Well said. liveliness as a default benchmark type would be good for just about everything. :) > With the advent of SDN and VNFs, the latency of a VNF would really make > lot of sense for the network operator for optimal network planning and > deployment. I agree that monitoring the effectiveness of these new technologies is a goodness. > Based on the real time latency, the network operator can possibly spawn > more VMs for a services VNF when required and can shut down some of >them > when not required. Well, more VMs does !=3D less latency. Vathsa>>>I agree. But just wanted to indicate that in some use cases, when load(number of sessions) on a VM increases, there could be a possibility of=20 the service latency getting increased.

We feel that service KPIs like load, latency etc for Router services(like DPI, CGNAT, IPSEC)=20 may not be the scope of this extension.

Before we create what could be a weird set of relationships bet= ween
documents, has anyone polled the WG on their interest in
adopting/advancing Al's owamp-registry draft?

It appears from the above comment that the WG hasn't been asked about its interest in it, at least formally.

I th= ought we had a path forward for this document by creating the=C2=A0ippm-owamp-registry draft and adding a normative dependency= from this draft, but I'm not seeing that the working group has been po= lled about whether that's what the working group wants to do.

Could the chairs do that, and report back, so Kostas will k= now what to do with the reference?

Or, if that isn= 't the plan, could you catch us up?

Thanks!

Hello All,<= /span>

BTW, the only update to thi= s draft is to combine the layout with the original draft.

We are also working on an implementation of the draf= t (PDM) in FreeBSD.   We will have an update for you in Prague.

This draft is a work item of the IP Performance Metrics Working Group of the IETF. Title : Model Based Metrics for Bulk Transport Capacity Authors : Matt Mathis Al Morton Filename : draft-ietf-ippm-model-based-metrics-05.txt Pages : 46 Date : 2015-06-13 Abstract: We introduce a new class of model based metrics designed to determine if a complete Internet path can meet predefined bulk transport performance targets by applying a suite of IP diagnostic tests to successive subpaths. The subpath-at-a-time tests can be robustly applied to key infrastructure, such as interconnects or even individual devices, to accurately detect if any part of the infrastructure will prevent any path traversing it from meeting the specified target performance. The diagnostic tests consist of precomputed traffic patterns and statistical criteria for evaluating packet delivery. The traffic patterns are precomputed to mimic TCP or other transport protocol over a long path but are constructed in such a way that they are independent of the actual details of the subpath under test, end systems or applications. Likewise the success criteria depends on the packet delivery statistics of the subpath, as evaluated against a protocol model applied to the target performance. The success criteria also does not depend on the details of the subpath, end systems or application. This makes the measurements open loop, eliminating most of the difficulties encountered by traditional bulk transport metrics. Model based metrics exhibit several important new properties not present in other Bulk Capacity Metrics, including the ability to reason about concatenated or overlapping subpaths. The results are vantage independent which is critical for supporting independent validation of tests results from multiple Measurement Points. This document does not define diagnostic tests directly, but provides a framework for designing suites of IP diagnostics tests that are tailored to confirming that infrastructure can meet a predetermined target performance.

(b) whether you have read the draft=20 Yes, I have read it. Some comments: 1. Section 1, paragraph 1, 1st sentence, reads in part: "measurements of metrics specified by the IP Performance Metrics (WG in the= IETF" There may be a typo here, I suspect you want: "measurements of metrics specified by the IP Performance Metrics (IPPM) WG = in the IETF" 2. I wonder if it makes sense to add something like the following sentence= to either section 1. Introduction or Section 3.2.4 "OWAMP and TWAMP registries for commands and modes may contain different pa= rameters and functions due to the inherent differences in what they are mea= suring. No attempt will be made to coordinate them unnecessarily." (c) whether you pledge to review the draft during the WG process.=20 I so pledge. =20 Thanks, Nalini Elkins Inside Products, Inc.

The first mission of an OWAMP registry would be to suppo= rt a registry entry for draft-ietf-ippm-ipsec, which is currently in IESG e= valuation. Please indicate: (a) whether you support the addition of the milestone and the adoption=20 of the draft as a WG item to fulfill that milestone=20 (b) whether you have read the draft=20 (c) whether you pledge to review the draft during the WG process.=20 This working group last call runs for 2 weeks, but if there is sufficient s= upport the draft may be accepted earlier so that draft-ietf-ippm-ipsec can = progress. Also, draft-elkins-ippm-6man-pdm-option has been accepted for adoption by t= he IPPM working group.

I would like to see smokeping more widely used, and bandwidth presented at the same time as loss, ECN CE, and latency in more mtrg and cacti (and other widely used network management system) graphs. While I would like to see more twamp deployments, it is kind of a headache to deploy (ntp time sensitivity for starters - that said, I would also like to see better timekeeping across the internet also). Vathsa>>> For RTT calculations the NTP synchronization should not matter. Anyways the PTP(Precision Time Protocol) should provide more precision than NTP which is being deployed of late. For monitoring service KPIs like latency we are always interested in delta and not the actual time stamps. For other service KPIs like load, capacity we are not interested in time at all. > > Today TWAMP is used to measure just RTT between 2 Network Elements, like > routers, servers etc. > Since Routers are no more just forwarding packets but running lot more > services like CGNAT, DPI, IPSec, TDF and like. > Even Servers are used to run applications like DNS, HTTP over it. > > Existing standard protocols cannot measure the impact of enabling service > on packets that get routed via a router in terms of latency and the > throughput. > Similarly they cannot figure out the liveliness of an application on a > server even though they can figure out that the server is alive.

Well, more VMs does !=3D less latency. Vathsa>>>I agree. But just wanted to indicate that in some use cases, when load(number of sessions) on a VM increases, there could be a possibility of=20 the service latency getting increased.

We feel that service KPIs like load, latency etc for Router services(like DPI, CGNAT, IPSEC)=20 may not be the scope of this extension. This is a good extension for host to host architecture. regarding: > > Similarly they cannot figure out the liveliness of an application on a > > server even though they can figure out that the server is alive. >=20 > Well said. liveliness as a default benchmark type would be good for just > about everything. :) By liveliness, what degree of response complexity is considered alive? Possibilities beyond ICMP Echo include: - Opens connection on well-known port - sends expected greeting message - ... - completes entire transaction within time limit Vathsa>>> For some TCP applications, opening a connection on well-known port is liveliness. For some UDP applications, receiving greeting message is liveliness. For some applications like HTTP, DNS it can be one transaction within time limit. regards, Al > -----Original Message----- > From: ippm [mailto:ippm-bounces@ietf.org] On Behalf Of Dave Taht > Sent: Monday, June 08, 2015 12:31 PM > To: Srivathsa Sarangapani > Cc: ippm@ietf.org > Subject: Re: [ippm] Discussion on extending TWAMP to monitor service > KPIs and detect liveliness of an application >=20 > On Mon, Jun 8, 2015 at 9:17 AM, Srivathsa Sarangapani > wrote: > > Dear IPPM, > > > > I would like to share something with you today. > > > > In the existing as well as next generation network architectures, > > there are lot of new services getting added in the service plane with > > in the network. services here include subscriber aware services, flow > > based traffic load balancing, content delivery servers, real time > > streaming applications and similar.

Services Keepalive Monitoring The Session-Sender MAY send the Service PDU as part of the TWAMP-Test Packet Padding. When Session-Reflector receives the TWAMP-Test packet, it SHALL extract the Service PDU. Then Session-Reflector SHALL inject the Service PDU to the Service Block for service processing. Based on whether the Session-Reflector received the response, the Session-Reflector SHALL decide whether the Service is alive or not. Are the test packets sent between Sender and Reflector the basis for=20 evaluating Service liveliness? If so, it seems that *any* successful test packet received at the Reflector and then received back at the Sender is enough to assess bi-directional service liveliness. I'm missing the need for the Reflector to decide anything - it just has to re-use payload in the packet it reflects?

Sorry, if the explanation is not clear in the draft. Please see my answers inline: --=20 Regards, Vathsa -----Original Message----- From: "MORTON, ALFRED C (AL)" Date: Tuesday, June 30, 2015 at 6:49 AM To: Srivathsa Sarangapani , Dave Taht Cc: "ippm@ietf.org" , Peyush Gupta Subject: RE: [ippm] Discussion on extending TWAMP to monitor service KPIs and detect liveliness of an application Hi Vathsa, I had a look at your draft tonight, but I clearly need to spend more time to try to figure out how these new features work - take the keep-alive for example in section 5.1: 5.1. Services Keepalive Monitoring The Session-Sender MAY send the Service PDU as part of the TWAMP-Test Packet Padding. When Session-Reflector receives the TWAMP-Test packet, it SHALL extract the Service PDU. Then Session-Reflector SHALL inject the Service PDU to the Service Block for service processing. Based on whether the Session-Reflector received the response, the Session-Reflector SHALL decide whether the Service is alive or not. Are the test packets sent between Sender and Reflector the basis for evaluating Service liveliness? Vathsa>>>No.=20 If this alone was solving the purpose, then TWAMP does this functionality as of today. If so, it seems that *any* successful test packet received at the Reflector and then received back at the Sender is enough to assess bi-directional service liveliness. I'm missing the need for the Reflector to decide anything - it just has to re-use payload in the packet it reflects? Vathsa>>>We mean to say that the TWAMP reflector module should extract the Service PDU from the TWAMP data packet. Please note that this Service PDU is filled by Session-Sender when it sends the Test packet. The Session-Reflector should inject the Service PDU to the Service Block. Once the packet is received back at the reflector from the Service Block, it will reply back to Session-Sender. By this the Session-Sender is sure of 2 things: - The box where Session-Reflector is running is alive - The Service Block is also working fine. Say for example, the HTTP server might be alive but the HTTP Server daemon might not be working. So these kinds of problems can be caught using our proposed extension. Another example would be say a Router is running some Services like CGNAT(JFLOW,DPI) outside the box as a VNF(say on a X86 cots server). This router can run a TWAMP Session-Reflectot and using our extension, the Session-Reflectore SHALL inject a test Service PDU to CGNAT VNF. Based on the reply(possibly comparing the reply packet with expected packet), the Session-Sender can really know if the CGNAT module is working as expected or not. Not just the liveliness, other service parameters like: - How many sessions are currently running a part of this VNF(to know the current load on a VNF) - What is the extra latency being introduced for enabling CGNAT service in a VNF. These information can be the basis for the network operator to spawn more VNFs or use some Service block inside the router for some gold customers and use VNF for other customers etc. Basically we want to aid the Network administrator with the live data regarding Service Load, Service latency etc so that he can plan his network for best results. Please let me know if you need more info and we can provide the same.
