3/20/2002 IESG Plenary IETF 53, Minneapolis

Current Results-01 Draft

• 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

3/20/2002 IESG Plenary IETF 53, Minneapolis

Current Results (-02)Full Standards

• Requirements for Internet Hosts (RFC 1122 & 1123)

• Router Requirements (RFC 1812)• Network Time Protocol (RFC 1305)• Netbios over TCP/UDP (RFCs 1001 & 1002)• IP over HyperChannel (RFC 1044)• IP over Netbios (RFC 1088)• IP over SMDS (RFC 1209)

3/20/2002 IESG Plenary IETF 53, Minneapolis

Current Results (-02)Draft Standards

• SMDS MIB (RFC 1694)• The PPP Multilink Protocol (RFC 1990)

– A new class identifier for IPv6 packets must be registered with the IANA. It is RECOMMENDED that the (currently unassigned) value of 6 be assigned by the IANA with a description of "Internet Protocol (IPv6) Address." An application for this assignment has been sent to the IANA.

Next Steps

• -02 Draft will be submitted after the conclusion of the meeting

• Request to the IESG for a last call period and publication as an Informational RFC

• Then its up to the WGs and the rest of the IETF to decide what to update

How You Can Help

• READ THE DRAFT AND COMMENT

• Ingest large amounts of caffeine

• REREAD THE DRAFT AND COMMENT

• … and in case it isn’t clear

• READ THE DRAFT AGAIN AND COMMENT– It’s over 200 pages of gripping narrative, enjoy!

On The Classification of Standards

• There are 61 Full Standards– 4 of which have been reclassified to Historic.

• There are 65 Draft Standards, 611 Proposed Standards, and 150 Experimental RFCs– Only 66 have been reclassified as Historic

• That is a rate of less than 8%.• It should be obvious that in the more that 30 years of

protocol development and documentation there should be at least as many (if not a majority of) protocols that have been retired compared to the ones that are currently active.

3/20/2002 IESG Plenary IETF 53, Minneapolis

Current Process Is Flawed

• We need to fix this problem• It’s like a 30 year Bookstore that has 92%

of its books in the New Release Section• The biggest problem is that “new” protocols

are either Proposed Standards or Experimental RFCs– They can, have and do linger for more that 15

years without any movement

3/20/2002 IESG Plenary IETF 53, Minneapolis

Why? Two Reasons

• Standards progress when they are championed

• NNTP (RFC 977 February 1986)– Proposed standard

• IESG typically takes action only by request(too much work)

• RFC Editor is overworked

• RFC publication rate is huge (almost 1 per work day)

• RFCs are bigger and more complicated

• Primarily looking at the present and future

3/20/2002 IESG Plenary IETF 53, Minneapolis

How Do We Deal With The Orphans?

• We don’t!

• We need a large one-time effort to clean up the protocol suite

• We need regular review to keep the things from getting out of hand in the future
