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 draft describes the set of functions that constitute the MPLS Transport Profile (MPLS-TP) data plane. The document Security Considerations section clearly states that the data plane itself does not provide any security mechanisms, other portions of the document appear to be consistent with that statement. The brief description of management or control plane use of security features as well as the discussion about enhanced security in Security Considerations appear to be adequate. Russ Mundy
