Title : Constrained Application Protocol (CoAP)
Author(s) : Z. Shelby, et al.
Filename : draft-ietf-core-coap-01.txt

This document specifies the Constrained Application Protocol (CoAP),
a specialized RESTful transfer protocol for use with constrained
networks and nodes for machine-to-machine applications such as smart
energy and building automation. These constrained nodes often have
8-bit microcontrollers with small amounts of ROM and RAM, while
networks such as 6LoWPAN often have high packet error rates and a
typical throughput of 10s of kbit/s. CoAP provides the REST Method/
Response interaction model between application end-points, supports
built-in resource discovery, and includes key web concepts such as
URIs and content-types. CoAP easily translates to HTTP for
integration with the web while meeting specialized requirements such
as multicast support, very low overhead and simplicity for
constrained environments.
