Greetings. draft-ietf-taps-transports, "Services provided by IETF transport protocols and congestion control mechanisms", is an informational overview of a large number of transport protocols. It does not change any of the protocols, just compares them. The Security Considerations section says "This document does not specify any new features or mechanisms for providing these features", which is appropriate and correct. In addition, Section 5, which collects some of the comparisons of features, lists security features and says which of the transport protocols support them. In that list, it says that replay protection is offered by FLUTE/ALC and DTLS, but does not list TLS. That seems like an oversight because DTLS and TLS offer similar replay semantics. (The rest of the list seems sensible.) --Paul Hoffman
