Body |
The CCAMP working group notes your request to review its work on Multi-Layer Networking (MLN) as indicated in your liaison "Liaison Statement to CCAMP responding to ccamp liaison of 21 February 2007" dated March 2007. We are nearing completion of our analysis of the requirements for MLN, and our evaluation of existing protocols, so now is an appropriate time for you review this material, and we would be grateful for your comments on or before the deadline marked above. The requirements work can be found at http://www.ietf.org/internet-drafts/draft-ietf-ccamp-gmpls-mln-reqs-02.txt The protocol evaluation is at http://www.ietf.org/internet-drafts/draft-ietf-ccamp-gmpls-mln-eval-02.txt In your review of this material, it may be helpful to pay particular care to understand the definition of MLN that is used. It may also be helpful to use some of the terminology interpretation presented in RFC4397. The CCAMP working group also anticipates working on protocol extensions to fill the lacunae identified by the protocol evaluation Internet-Draft. An individual submission on this subject may be found at http://www.ietf.org/internet-drafts/draft-papadimitriou-ccamp-gmpls-mrn-extensions-03.txt, but the working group has yet to make a decision about whether to accept this as the basis for the work. We note that in a liaison dated February 2004 discussing the signaling requirements for ASON and reviewing draft-ietf-ccamp-gmpls-ason-reqts-05.txt you said: 11. G.8080 defines the ASON control plane as applying to a single layer. Some examples in the draft involve multiple layers. While not precluded by implementations, a suggested replacement example is contained in the marked up copy that is single layer. Could you please confirm your current view of the definition of the ASON control plane in G.8080. Does the ASON control plane now apply to more than one layer? Could you please provide references to the appropriate sections of your Recommendations. Best regards, Adrian Farrel and Deborah Brungard Co-chairs, IETF CCAMP Working Group |
