The IESG has received a request from the IPv6 Maintenance WG (6man) to consider the following document: - 'Applicability Statement for the use of IPv6 UDP Datagrams with Zero Checksums' <draft-ietf-6man-udpzero-08.txt> as Proposed Standard This Last Call is the second IETF Last Call for this document. The first Last Call was to publish this document as an Informational document. The draft has been restructured as an applicability statement and is intended to be published as a Proposed Standard. The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-12-26. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document provides an applicability statement for the use of UDP transport checksums with IPv6. It defines recommendations and requirements for the use of IPv6 UDP datagrams with a zero UDP checksum. It describes the issues and design principles that need to be considered when UDP is used with IPv6 to support tunnel encapsulations and examines the role of the IPv6 UDP transport checksum. An appendix presents a summary of the trade-offs that were considered in evaluating the safety of the update to RFC 2460 that updates use of the UDP checksum with IPv6. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-6man-udpzero/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-6man-udpzero/ballot/ No IPR declarations have been submitted directly on this I-D.
