I have reviewed this document as part of the security directorate's 

ongoing effort to review all IETF documents being processed by the 

IESG.  These comments were written primarily for the benefit of the 

security area directors.  Document editors and WG chairs should treat 

these comments just like any other last call comments.



This is a Standard Track document that extend the GMPLS OSPF routing protocol by introducing 

an optional ISCD Availability sub-TLV, which could be used for route computation in a network that contains links with variable discrete bandwidth. This document defines the distribution mechanism for this new extension.

The Security Consideration section clearly describes the security and privacy issues with this new extension, and since this is only an extension to an existing mechanism, it points to other documents that cover the mechanism and the security implications and potential solutions.
