IPv6 Benchmarking Methodology

  Velde, Diego Dugatkin

IETF 69, July 22nd 2007 Chicago

• Agenda
• Overview
• Last Call Review
• Last Call Discussion
• Next steps

A document providing guidance in the area of
IPv6 benchmarking would be welcome to
organizations (including the US federal agencies
mandated to deploy IPv6 on their backbone
networks) attempting to understand why and how
network device IPv6 performance must be tested. A
document that attempts to define which areas need
to considered and which describes how to
test/benchmark these areas may be well received.
Bill Cerveny

• Overview
• Complements RFC2544 by
• Adds benchmarking methodology recommendations
  that address specific aspects of IPv6 protocol
  architecture
• Provide an updated list of benchmarks based on
  the experience gained with applying the RFC2544
  recommendations to IPv4
• Adds information related to SONET as a popular
  media type not mentioned by RFC2544
• Went through several rounds of review within BMWG
  and v6ops WG

4
Overview (cont.)

• Interest
• Expressed by networking and test tool vendors
• There is at least one implementation of the draft
  in a benchmarking suite
• Used in benchmarking related to the OMB and DoD
  IPv6 mandates.
• Timeline
• Voted WG Working Item during the Montreal IETF
  66th meeting
• Currently in final WG Last Call until August 10

Last Call Discussion

• Additional comments and recommendations from
• David Newman (Topic maximum throughput)
• Dan Romascanu, Scott Bradner, David Newman
  (Topic jumbo frames)
• Timmons Player, Curtis Villamizar, Scott Bradner
  (Topic back-to-back test)
• Scott Bradner (Topic throughput definition)
• All these topics were addressed as documented in
• http//home.comcast.net/7Eacmacm/BMWG/IPv6-meth-c
  omment-resolution.pdf

Last Call Discussion (Cont.)

• One open item
• David Newman (Topic SONET minimum frame size and
  accounting for the presence of signature fields
  in packets)
• Proposed resolution
• Ethernet 64, 128, 256, 512, 1024, 1280, 1518
  bytes
• SONET 47, 64, 128, 256, 512, 1024, 1280, 1518,
  2048, 4096 bytes
• Include a note for the following topics
• - 47 was chosen as the limit case
• - how to select a minimum frame size to include
  the signature field

IPv6 Benchmarking test suite Vendor
implementation

• RFC2544/IPv6 Benchmark Suite, based on this IETF
  draft
• Traffic Setup enhancements
• IP/IPv6 dual stack
• Test Setup Additions
• IPv6 Extension Headers
• IP/IPv6 traffic ratio

9
IPv6 Benchmarking test suite Vendor
implementation

• Signature PatternSignature (4B)
• PacketGroupID
• SequenceNumber
• DataIntegrityChecksum
• TimeStamp
• (default 20 B) (variable size 2 to 12, default
  4B)
• (optional field, fixed-size 4 Bytes)
• (optional field, fixed-size 4 Bytes)
• (optional field, fixed-size 2 Bytes)
• (optional field, fixed-size 6 Bytes)

10
Next Steps

• The draft is currently in a final Last Call for
  the period 14 July 2007 through 10 August 2007
• Next Steps
• Reach agreement on the last open item minimum
  frame size for SONET and inclusion of signature
  field
• Include any additional comments
• Deliver the final version of the draft for
  publication

• draft-ietf-bmwg-ipv6-meth-02
• THANK YOU!

12

• Document Goals
• Address a very acute and growing need for
  recommendations on evaluating network element
  performance for IPv6 deployments
• A complement rather than a replacement of RFC2544
  in accordance with BMWG strategy
• Provide the additional, IPv6 specific guidelines
  to IP benchmarking while indicating the aspects
  of RFC2544 that are IP version independent
• Maintain the structure and spirit of RFC2544.
