Summary: This document will be ready for publication as soon as the
major issue (below) below is addressed.
Major Issues:
This document contains a normative reference to draft-ietf-conex-destopt-09.
The normative reference is appropriate, because this document doesn't work at
all unless the concepts described in draft-ietf-conex-destopt-09 work.
I am concerned about draft-ietf-conex-destopt-09. It uses an IPv6 Destination
Option to signal CONEX state to intermediate routers. However, according to RFC
2460:
"With one exception, extension headers are not examined or processed
by any node along a packet's delivery path, until the packet reaches
the node (or each of the set of nodes, in the case of multicast)
identified in the Destination Address field of the IPv6 header."
The exception to which RFC 2460 refers is the Hop-by-hop Extension Header.
Intermediate routers don't examine Destination Options.
Section 5 of draft-ietf-conex-destopt-09 attempts to address this issue, but I
am not sure that the argument is acceptable.
Minor Issues: None
