Subject: Crankback in GMPLS Systems

Dear Mr. Lam,

The IETF's CCAMP Working Group notes that recent contributions to your question in SG15
have proposed adding the requirements, architecture and solutions for crankback
routing/signaling to your scope of work.

We would like to draw your attention to the work already done in the CCAMP Working Group
on this topic. The attached draft includes a discussion of requirements and solutions for
crankback within GMPLS systems.

The CCAMP Working Group would welcome input from SG15 on this work.

Sincerely,
Kireeti Kompella & Adrian Farrel, CCAMP WG chairs
