Title : IPv6 UDP Checksum Considerations
Author(s) : G. Fairhurst, et al
Filename : draft-ietf-6man-udpzero-03.txt
Pages : 33
Date : 2011-04-21
This document examines the role of the UDP transport checksum when
used with IPv6, as defined in RFC2460. It presents a summary of the
trade-offs for evaluating the safety of updating RFC 2460 to permit
an IPv6 UDP endpoint to use a zero value in the checksum field as an
indication that no checksum is present. This method is compared with
some other possibilities. The document also describes the issues and
design principles that need to be considered when UDP is used with
IPv6 to support tunnel encapsulations. It concludes that UDP with a
zero checksum in IPv6 can safely be used for this purpose, provided
that this usage is governed by a set of constraints.
