Hi Igor, I am not sure which implementation you want the results for. We have done tests on our implementation, however I am not sure we can disclose it. Similar tests done on Cisco are however at the page: - Experience in Black-box OSPF Measurement http://www.research.att.com/%7Ealbert/papers/sigcom-imw01/mes-ws01-paper.pdf Thanks, Vishwas -----Original Message----- From: bmwgeuro [mailto:bmwgeuro <at> libero.it] Sent: Monday, June 16, 2003 18:33 To: bmwg Subject: [bmwg] Bechmarking methology of basic OSPF convergence Hi, i need information and test result about the Bechmarking methodology for bacic OSPF Convergence. Thanks, Igor

BMWG'ers: A WG Last Call period for the Internet-Drafts regarding OSPF convergence benchmarking terminology, methodology, and benchmark applicability: <draft-ietf-bmwg-ospfconv-term-04.txt>, <draft-ietf-bmwg-ospfconv-intraarea-05.txt>, <draft-ietf-bmwg-ospfconv-applicability-03.txt> will be open from 17 June 2003 until 1 July 2003. Input from previous WG Last Calls have been incorporated in the I-Ds; the editors believe the I-Ds are ready for advancement. Please weigh in on whether or not you feel each individual draft should not be given to the Area Directors for consideration in progressing the draft to an Informational RFC. Send your comments to this list or kdubray <at> juniper.net.

Igor, Do you want convergence time as observed by network customers? The referenced paper below deals with only a few components of the overall convergence time for a single router. That is why you see results in milliseconds presented. Of course, under network conditions, network customers observe IGP convergence times in seconds and BGP convergence times in tens of seconds. It would be great to have a single source on the web to compare convergence time for various routers, but there is not. You could ask your vendor, but chances are you will get a number under optimum conditions that are not realistic for your network. The best way to obtain convergence times is to measure it in your lab under your simulated network conditions.

Hello, I submitted a modified draft on Benchmarking Terminology for Protection Performance: http://www.ietf.org/internet-drafts/draft-kimura-protection-term-01.txt. The summary of changes: - More description on the types of recover paths is added to avoid dependence on a specific sub-IP layer protection technology. - Loss of Service, Out-of-Order Packet and Duplicated Packet are deleted to avoid confusion for first one and to avoid redefinition for last two ones. Please send any discussion comments on this draft to the list. Thanks, Takumi

The result of the call for the BMWG to consider undertaking goals described in the associated proposal, dated 9 APR 03, is that the WG will add the production of a terminology and methodology set of drafts specifying the benchmarking of router software under accelerated stress conditions to the WG docket. The appropriate milestones will be added to the BMWG charter page. Scott Poretsky (sporetsky <at> avici.com) is the primary editor.

The result of the call for the BMWG to consider undertaking goals described in the subject proposal, dated 23 APR 03, is that the WG will add the production of applicability, terminology, and methodology drafts that specify the benchmarking of IGP convergence in routers and systems under test to the WG docket. The appropriate milestones will be added to the BMWG charter page. Scott Poretsky (sporetsky <at> avici.com) is the primary editor.

This draft is a work item of the Benchmarking Methodology Working Group of the IETF.
Title : Benchmarking Methodology for IGP Data Plane Route
Convergence
Author(s) : S. Poretsky, B. Imhoff
Filename : draft-ietf-bmwg-igp-dataplane-conv-meth-00.txt
Pages : 10
Date : 2003-6-19
This draft describes the methodology for benchmarking IGP Route
Convergence. The applicability of this testing is described in
[1] and the new terminology that it introduces is defined in [2].
Service Providers use IGP Convergence time as a key metric of
router design and architecture. Customers of Service Providers
observe convergence time by packet loss. IGP Route Convergence
is a Direct Measure of Quality (DMOQ) when benchmarking the data
plane and not the control plane. The test cases in this document
are black-box tests that emulate the network events that cause
route convergence, as described in [1]. Black-box test design
accounts for all of the factors for route convergence time, as
provided in [1]. The methodology and terminology is to be used
for benchmarking route convergence and can be applied to any
link-state IGP such as ISIS [3] and OSPF [4].

Title : Terminology for Benchmarking IGP Data Plane Route
Convergence
Author(s) : S. Poretsky
Filename : draft-ietf-bmwg-igp-dataplane-conv-term-00.txt
Pages : 9
Date : 2003-6-19
This draft describes the terminology for benchmarking IGP Route
Convergence. The motivation and applicability for this
benchmarking is provided in [1]. The methodology to be used for
this benchmarking is described in [2]. The methodology and
terminology to be used for benchmarking route convergence can be
applied to any link-state IGP such as ISIS [3] and OSPF [4]. The
data plane is measured to obtain the convergence benchmarking metrics.
The purpose of this document is to introduce new terms required to
complete execution of the IGP Route Convergence Methodology [2].
