Hi, all,

Here's a short summary of the changes.

Joe

----

- a few typo fixes

- removed discussion on ID for ICMP validation (it never got out of the proposed stage)

- changed from "Cocode" to "mathematical expression" to avoid needing a BSD-stye license (since the example wasn't intended as running code anyway)

- formalized the recommendation that SMF treat IPv4 like IPv6, i.e., use hashes rather than the ID field for duplicate packet detection

- expanded the header compression discussion with new examples

- included discussion on use of the ID field for debugging, and alternates (which are needed for IPv6 anyway)

- added ACKs for the recent contributors (thanks, BTW)

	Title           : Updated Specification of the IPv4 ID Field
	Author(s)       : Joe Touch
	Filename        : draft-ietf-intarea-ipv4-id-update-04.txt

    The IPv4 Identification (ID) field enables fragmentation and
    reassembly, and as currently specified is required to be unique
    within the maximum lifetime for all datagrams with a given
    source/destination/protocol tuple. If enforced, this uniqueness
    requirement would limit all connections to 6.4 Mbps. Because
    individual connections commonly exceed this speed, it is clear that
    existing systems violate the current specification. This document
    updates the specification of the IPv4 ID field in RFC791, RFC1122,
    and RFC2003 to more closely reflect current practice and to more
    closely match IPv6 so that the field's value is defined only when a
    datagram is actually fragmented. It also discusses the impact of
    these changes on how datagrams are used.
