The IESG has approved the following document: - 'Too Many Requests Response Code for the Constrained Application Protocol' (draft-ietf-core-too-many-reqs-06.txt) as Proposed Standard This document is the product of the Constrained RESTful Environments Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-core-too-many-reqs/ Technical Summary: A 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. Working Group Summary: While this seemed to be a simple housekeeping document (based on other SDOs' requests) at first, the WG process did unearth a few fine points that have been taken care of in the current document. WGLC was passed July 16, 2018 (right before the CoRE meeting in Montreal), there was no dissent on advancing this. Document Quality: While no formal review was sent to the list, both Jim Schaad and Klaus Hartke sent comments based on an in-depth review and later indicated that their comments had been resolved in -04. Implementers indicated intent to implement this. No formal languages in the document. Personnel: Shepherd: Carsten Bormann Responsible AD: Alexey Melnikov
