[secdir] secdir review of draft-ietf-tcpm-2140bis

[Carl Wallace <[e-mail]>]

I 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 authors, document editors, and WG chairs should treat these comments just like any other IETF Last Call comments.

This document obsoletes RFC 2140. It provides a description of interdependent TCP control blocks and the ways that part of TCP state can be shared among similar concurrent or consecutive connections. TCP state includes a combination of parameters, such as  connection state, current round-trip time estimates, congestion  control information, and process information. 

I found no issues or nits with the document. The document is ready.
