A single CoAP message is typically encapsulated and transmitted using UDP or DTLS as transports. These transports are optimal solutions for CoAP use in IP-based constrained environments and nodes. However compelling motivation exists for understanding how CoAP can operate with other transports, such as the need for M2M communication using non-IP networks, improved transport level end-to- end reliability and security, NAT and firewall traversal issues, and mechanisms possibly incurring a lower overhead to CoAP/HTTP translation gateways. This draft examines the requirements for conveying CoAP messages to end points over such alternative transports. It also provides a new URI format for representing CoAP resources over alternative transports.}, }
