The Constrained Application Protocol (CoAP), while inspired by HTTP, has been defined to make use of UDP instead of TCP. Therefore, reliable delivery and a simple congestion control and flow control mechanism are provided by the message layer of the CoAP protocol. A number of environments benefit from the use of CoAP directly over a reliable byte stream such as TCP, which already provides these services. This document defines the use of CoAP over TCP as well as CoAP over TLS.}, }
