Californium (Cf) CoAP framework in Java

Californium (Cf) is a modular CoAP implementation written in Java using a flexible, layered architecture. It allows easy creation of cloud-based client and server applications as well as CoAP proxies. We currently support draft-ietf-core-coap-08, draft-ietf-core-block-08, draft-ietf-core-observe-05, and draft-ietf-core-link-format-11.

Our Java implementation was successfully tested at the ETSI IoT CoAP Plugtest in Paris, France, March 2012. It passed all mandatory and optional tests with all the other implementations that supported them. Our Californium test server is available at coap://vs0.inf.ethz.ch:5683/ and provides the Plugtests together with additional resources.
