Summary: Ready with issues

Major issue:

The draft does not mention the IP version.  RFC 2330 states that it applies to IPv4
only (section 15) and uses terminology that only applies to IPv4. At the very minimum,
the current draft needs to state its limited applicability. I would be much happier if it
explained how it applies to IPv6.

Minor issues:

In sections 3.6 and 3.8.1 there are passing references to the diffserv code point. I think
that the ECN bits should be mentioned too: their setting could also affect router processing
time. ECN is a bit tricky as it might change on the fly.

Along the same lines, should Router Alert be mentioned? And for IPv6 applicability,
any hop-by-hop options should certainly be mentioned.
