I reviewed the document "OSPF-TE Link Availability Extension for Links with Variable Discrete Bandwidth" (draft-ietf-ccamp-ospf-availability-extension-08.txt) as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the operational area directors. Document editors and WG chairs should treat these comments just like any other last call comments. Intended status: Standards Track Current IESG state: AD is watching IANA State: IANA OK - Actions Needed Summary: The document introduces an optional Interface Switching Capability Descriptor (ISCD) Availability sub-TLV to extend the GMPLS Open Shortest Path First (OSPF) routing protocol for TE links with variable discrete bandwidth. It has been recently extended to make it generic to apply to multiple technologies. There are a few minor nits in the document: The text in section 2 line 2 is misspelled: "include a< availability, bandwidth> information list in its OSPF" s/e(s).The/e(s). The/ The document has been written with a proper language. I think the document does not cause any issue related to operations and management and can be published. Mehmet
