• NGTRANS WG Meeting
• 52nd IETF, Salt Lake City

Agenda

• Brief Introduction Overview
• Current Results
• Next Steps
• How You Can Help

3
Introduction Overview

• Work Started in late 1999
• First draft (-00) in May 2000
• Second (current) draft (-01) in August 2001
• Goal of the project is to review all of the
  current IETF Standards for IPv4 assumptions to
  make sure a transition to IPv6 as smooth as
  possible

4
Introduction Overview(cont)

• Full Standards
• 68 RFCS
• Draft Standards
• 65 RFCS
• Proposed Standards
• 611 RFCS
• Experimental
• 150 RFCS

5
Introduction Overview(cont)

• Most of the work has been done as an individual
  effort
• Reading Each of the 894 RFCS
• About 25,000 pages of text
• PLEASE LOOK AT THE DRAFT FOR ANY RFCS THAT YOU
  HAVE KNOWLEDGE OF AND COMMENT

6
Current Results

• The 01 draft was concerned with finding RFCS
  with problems
• Full Standards 26 RFCS (38.25)
• Draft Standards 19 RFCS (29.23)
• Proposed Standards 112 RFCS (18.33)
• Experimental 23 RFCS (15.33)
• Total 180 RFCS (20.13)

7
Current Results(cont)

• Each RFC was examined independently of all others
• Technique purposely chosen to give more false
  positives rather than accidentally missing
  something
• Helped reduce the scope of the individual
  investigation

8
Current Results(cont)

• In the middle of reviewing the RFCS that came up
  positive in the first pass to see what problems
  are already fixed in later RFCS
• It is clear that many issues are already
  resolved, are in work, or can be fixed by
  registering a parameter with the IANA

9
Next Steps

• Finish review of RFCS identified in the first
  pass to finalize a list of problem child RFCS
  that need some updates
• At the request of the IETF chair the project
  should also include a discussion of protocols
  that assume the long term stability of addresses

10
Next Steps(cont)

• Produce an 02 draft that summarizes the final
  results of the review later this month or early
  next month
• Produce a series of recommendations for any RFCS
  that still have problems and include a discussion
  on the long term stability of address in an 03
  draft in early 2002
• Go to Last Call after the 03 draft is published
