Summary

This Recommendation specifies the signalling mechanism and protocol for distributed call and connection management based on GMPLS CR-LDP. This signalling protocol is applicable at the UNI, I-NNI and E-NNI and provides for automated call and connection operations relating to ASTN and ASON. Routing, DCN usage, and automatic discovery are beyond the scope of this Recommendation. Items covered in this Recommendation include:

–           CR-LDP messages;

–           CR-LDP attributes; and

–           CR-LDP signal flows.

This Recommendation meets the requirements of ITU-T Rec. G.7713/Y.1704 and is functionally similar to ITU-T Recs G.7713.1/Y.1704.1 and G.7713.2/Y.1704.2.
