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 is an update to the Roadmap for TCP specifications (RFC 4614). The roadmap provides a pointer (along with a brief abstract) to key TCP specifications. The update to the roadmap makes small changes to the organization of the roadmap and (more importantly) adds pointers to a number of more recent TCP-related specifications. This document appears to be ready for publication. I found no problems with this document. As a collection of pointers to other specifications, this document does not introduce any new security concerns. Security issues related to TCP are addressed in individual specifications referenced in this roadmap. (Indeed, one of the changes made in this update to the roadmap is to include more pointers to documents related to TCP security, such as the specification for TCP-AO.)
