Document: draft-ietf-core-echo-request-tag-11 Reviewer: Ines Robles Review Date: 2020-12-02 IETF LC End Date: 2020-12-02 IESG Telechat date: Not scheduled for a telechat Summary: This document specifies the Echo option that enables a CoAP server to verify the freshness of a request or to force a client to demonstrate reachability at its claimed network address, and specifies also the Request-Tag that allows the CoAP server to match block-wise message fragments belonging to the same request. Also, this document updates RFC7252 with respect to the client Token processing requirements. The document is well written, I have some minor questions/comments below. Major issues: None. Minor issues: None. Nits/editorial comments: 1.- It would be nice to have the definition of Freshness into the terminology section. 2.- Figure 1 and Figure 4 have two columns named "U" (Unsafe), is that Ok?, or should one of these columns be deleted/renamed? 3- Page 26: Please expand IV.
