Title : Observing Resources in CoAP
Author(s) : Klaus Hartke
Filename : draft-ietf-core-observe-10.txt
Pages : 31

Abstract:
CoAP is a RESTful application protocol for constrained nodes and
networks. The state of a resource on a CoAP server can change over
time. This document specifies a simple protocol extension for CoAP
that enables CoAP clients to "observe" resources, i.e., to retrieve
a representation of a resource and keep this representation updated
by the server over a period of time. The protocol follows a best-
effort approach for sending new representations to clients and
provides eventual consistency between the state observed by each
client and the actual resource state at the server.
