Abstract:
The Hypertext Transfer Protocol (HTTP) has been designed with TCP as
an underlying transport protocol. The Constrained Application
Protocol (CoAP), which has been inspired by HTTP, has on the other
hand been defined to make use of UDP. Reliable delivery, a simple
congestion control mechanism, and flow control had been added to the
CoAP protocol. UDP is a good choice for networks that do not perform
any form of filtering and firewalling. There are, however, many
deployment environments where UDP is either firewalled or subject to
deep packet inspection. These environments make the use of CoAP
brittle.
This document defines the use of CoAP over TCP as well as CoAP over
TLS.
