Q.14/15 would like to inform the IETF CCAMP Working Group of Q.14/15
activities on ASON signalling protocols. Initiation of this work
was communicated in a previous Q14/15 communication to the IETF dated 12
February 2002. Signalling documents in progress are:
Draft new Recommendation G.7713.2, based on the GMPLS RSVP-TE signalling
protocol
Draft new Recommendation G.7713.3, based on the GMPLS CR-LDP signalling
protocol
Contributions were considered that identified and proposed solutions to
add features to the signalling protocols that comply with the set of requirements
from G.807/Y.1302, G.8080/Y.1304 and G.7713/Y.1704. Text describing
support for soft permanent connections and logical call/connection separation
was added.
Please consider including the proposed solutions provided in G.7713.2
and G.7713.3 to update the existing GMPLS signaling work in support of
ASON requirements. We hope that you can help expedite the assignment of
appropriate additional error codes/values by IANA. These are needed
for both RSVP-TE and CR-LDP.
We are also commencing work on requirements for the next phase of our
effort that we expect might impact GMPLS protocol evolution, including:
-
Resilience mechanisms: Q12/15 has started work on control plane resiliency
requirements. Enhancements to the protocol (RSVP-TE, CR-LDP) for
resilience will be considered when these requirements are defined.
-
Support for control plane restoration of connections
Two documents are available at the ITU-T public ftp site for your information.
These are the two draft Recommendations as described above. Q.14/15
looks forward to your input to help progress this work in Q.14/15. A separate
Communication Statement has been sent to the Optical Internetworking Forum
(OIF) on this topic.
