Abstract

This document provides considerations for alleviating Constrained Application Protocol (CoAP) clients and intermediaries of keeping per-request state. To facilitate this, this document additionally introduces a new, optional CoAP protocol extension for extended token lengths.

This document updates RFCs 7252 and 8323 with an extended definition of the "TKL" field in the CoAP message header.


For the definition of Status, see RFC 2026.
