CCAMP, We need to send a communication to OIF in response to their Oct. 22nd communication. Let us know if any comments on this proposal. Deborah and Lou --------Proposal--------------------- Dear Lyndon, In your October 22nd communication, you requested consideration of a draft on inverse multiplexing "draft-roch-ccamp-gmpls-inv-mux-00.txt". This document was introduced at November's meeting. During CCAMP's Working Group Last Call discussion of "draft-ietf-ccamp-vcat-lcas", the use cases in draft-roch-ccamp-gmpls-inv-mux-00.txt as compared to the scope of draft-ietf-ccamp-vcat-lcas-08.txt were discussed. The use cases and ietms raised in draft-roch-ccamp-gmpls-inv-mux as we understand it are as follows: 1. IMG members are (statically) provisioned. 2. Members might be separately administered and policies may prevent signaling control information related to the IMG to be exchanged in the member signaling. 3. Control plane does not allow piggybacking of IMG information onto its own signaling. The use cases represented in 1. and 2. were considered out-of-scope of the CCAMP document. The scope of the CCAMP document is to support only scenarios where all members are signaled using the defined mechanism. CCAMP support for new functionality must be raised within the Working Group. We suggest that further discussion on these use cases take place based on an updated Internet Draft which is based on existing CCAMP work, i.e., draft-ietf-ccamp-vcat-lcas, which has passed last call. With respect to item 3, in the existing CCAMP work, only the VCAT end-points participate in signaling the IMG information, i.e., the intermediate signaling nodes do not participate in the VCAT call setup. If the end points do not support the CCAMP VCAT signaling mechanism, VCAT isn't provided. Again, the scope of the current work is to support only scenarios where all members are signaled using the defined extension. We welcome future contributions defining your requirements in the form of Internet-drafts. Please note that draft-ietf-ccamp-vcat-lcas is a product of the Working Group. As such, the Working Group will be focused on the reuse of this work in any future related work. As always, we encourage you to follow RFC4929's defined process. Regards, Lou Berger and Deborah Brungard IETF CCAMP Working Group Co-Chairs
