"Too Many Requests" Response Code for the Constrained Application Protocol
RFC 8516, “"Too Many Requests" Response Code for the Constrained Application Protocol”, is a Proposed Standard document published in January 2019 by A. Keranen. The canonical text is published by the RFC Editor.
Abstract
A Constrained Application Protocol (CoAP) server can experience temporary overload because one or more clients are sending requests to the server at a higher rate than the server is capable or willing to handle. This document defines a new CoAP response code for a server to indicate that a client should reduce the rate of requests.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
