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. The draft is ready for publication. Summary: I do not see any security concerns raised by this draft. The draft specifies benchmarking methods including report formats and metrics to consistently benchmark MPLS protection mechanisms. The draft does not specify the protection mechanisms. The security considerations section limits the recommended tests to closed environments, further limiting any possible security concerns. Best regards, Kathleen
