A new Request for Comments is now available in online RFC libraries. RFC 6936 Title: Applicability Statement for the Use of IPv6 UDP Datagrams with Zero Checksums Author: G. Fairhurst, M. Westerlund Status: Standards Track Stream: IETF Date: April 2013 Mailbox: gorry@erg.abdn.ac.uk, magnus.westerlund@ericsson.com Pages: 40 Characters: 99557 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-6man-udpzero-12.txt URL: http://www.rfc-editor.org/rfc/rfc6936.txt 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 it examines the role of the IPv6 UDP transport checksum. The document also identifies issues and constraints for deployment on network paths that include middleboxes. An appendix presents a summary of the trade-offs that were considered in evaluating the safety of the update to RFC 2460 that changes the use of the UDP checksum with IPv6. This document is a product of the IPv6 Maintenance Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements.
