Abstract:
This document provides an update of the Internet Protocol version 6
(IPv6) specification (RFC2460) to improve the performance in the use
case where a tunnel protocol uses UDP with IPv6 to tunnel packets.
The performance improvement is obtained by relaxing the IPv6 UDP
checksum requirement for any suitable tunnel protocol where header
information is protected on the "inner" packet being carried. This
relaxation removes the overhead associated with the computation of
UDP checksums on IPv6 packets used to carry tunnel protocols. The
specification describes how the IPv6 UDP checksum requirement can be
relaxed for the situation where the encapsulated packet itself
contains a checksum. The limitations and risks of this approach are
described, and restrictions specified on the use of the method.
