Abstract:
CoAP is being standardised as an application level REST-based
protocol. A single CoAP message is typically encapsulated and
transmitted using UDP. This draft examines the requirements and
possible solutions for conveying CoAP packets to end points over
alternative transports to UDP. UDP remains the optimal solution for
CoAP use in IP-based constrained environments and nodes. However 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 provide compelling motivation for
understanding how CoAP can operate in various other environments.
