The IESG has approved the following document: - 'Updated Specification of the IPv4 ID Field' (draft-ietf-intarea-ipv4-id-update-07.txt) as Proposed Standard This document is the product of the Internet Area Working Group. The IESG contact persons are Brian Haberman and Ralph Droms. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-intarea-ipv4-id-update/ Technical Summary 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. Working Group Summary The normal WG process was followed and the document as it stands now reflects WG consensus with nothing special worth mentioning. Document Quality The document was given adequate reviews. The Document Shepherd has no concerns about the depth or breadth of these reviews. Personnel The Document Shepherd for this document Julien Laganier. The responsible Area Director is Brian Haberman. RFC Editor Note OLD: Reordering is typically associated with routing transients or where multiple alternate paths exist. NEW: Reordering is typically associated with routing transients or where flows are split across multiple paths.
