Re: Working Group Last Call for <draft-ietf-6man-ipv6-alt-mark>

Dear All,
I've read the draft and I support its publication.

I have a question related to the operation of a node that applies the
Alternate Marking to a flow. As I understand it, the marking node (let's
call it that) will add an IPv6 header with the Options Header that includes
the AltMark Option. Is my understanding correct? If it is, then there would
be an impact on the packet sizes for the monitored flow. Some packets with
the additional IPv6 header might exceed the MTU. Should that be noted in
the Security Considerations? Can it be mitigated?

Also, text can benefit from editorial updates. I can give it a try if the
authors like to send me a text copy.

Regards,
Greg
