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 document talks about early retransmission considerations and protocols for TCP and SCTP. Its Security Considerations section is a pointer to RFC 5681, which lists some DoS attacks but indicates that no one has thought that hard about them. I think this is sufficient.
