The MPLS WG Archive

My dear MPLS colleagues,

I'm currently in London, attending the MPLS Next Generation Networking
conference. I came to this conference with one objective: finding out
how to map an LSP to specific ATM switching hardware, while using
RSVP-TE. For the last several weeks, I read RFCs 2205, 2210, 2212 and
several IETF drafts and still couldn't find one paper describing "an
edge LSR, sending a path message with these parameters set in the ADSPEC
and FLOWSPEC object, will receive, from a downstream node,  an ATM CBR
label mapping". (and so on and so forth for RT-VBR, NRT-VBR, UBR label
mappings).

Sounds easy doesn't it? After all, the CR-LDP IETF draft covers this in
only one page (appendix B).

After asking several questions to some expert speakers at the
conference, I was told that the reason I can't find the answer to my
question is not, because I didn't find the appropriate IETF draft, but
because this has not been addressed.

Moving forward, shouldn't this issue be addressed to ensure proper
multi-vendor QoS interoperability within a network CORE? After all, if
the CR-LDP draft covers this in one page... couldn't we have the same
guidelines for when a SP will deploy a multi-vendor MPLS CORE with
RSVP-TE?
