Abstract

CoAP has been standardised as an application-level REST-based protocol. When multiple transport protocols exist for exchanging CoAP resource representations, this document introduces a way forward for CoAP endpoints as well as intermediaries to agree upon alternate transport and protocol configurations as well as URIs for CoAP messaging. Several mechanisms are proposed: Extending the CoRE Resource Directory with new parameter types, introducing a new CoAP Option with which clients can interact directly with servers without needing the Resource Directory, and finally a new CoRE Link Attribute allowing exposing alternate locations on a per-resource basis.
