The IESG has approved the following document: - 'Description of the RSVP-TE Graceful Restart Procedures ' <draft-ietf-ccamp-gr-description-04.txt> as an Informational RFC This document is the product of the Common Control and Measurement Plane Working Group. The IESG contact persons are Ross Callon and David Ward. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-ccamp-gr-description-04.txt Technical Summary This document provides an informational clarification of the control plane procedures for a Generalized MPLS (GMPLS) network when there are multiple node failures, and describes how full control plane state can be recovered in different scenarios where the order in which the nodes restart is different. Working Group Summary There were no problems with consensus for this document (see PROTO writeup by Deborah Brungard). There was some debate about the need for this work. It was suggested that all of the necessary explanation of the operation of graceful restart was included in RFC 5063. However, repeated questions about how to use the protocol extensions in corner cases and double faliure scenarios makes this work valuable. Document Quality This document has been reviewed by the CCAMP working group and received some comments at IETF meetings and on the mailing list. Most importantly it has had input from the authors of RFC 5063 that documents the protocol procedures. It has also been updated in response to Gen-Art review. There are several implementations of the graceful restart processes described in RFC 5063. Experience from these implementations has provided valuable input to this document. Personnel Deborah Brungard is the Document Shepherd for this document. Ross Callon is the Responsible Area Director. There are no IANA actions.
