WebSocket is a full-duplex transport protocol that can operate over a single socket and does not suffer from network restriction such as proxies and firewalls when establishing a duplex channel. The services based on JAXRS, such as those provided by CXF and the new OData services provided by Olingo can take advantage of WebSocket.

However, to layer those JAXRS based services on top of WebSocket requires some protocol agreements to exchange the information required to invoke those services. Swagger-Socket, which is implemented using Atmosphere, is one such protocol that can be used by the existing CXF and Olingo services to directly utilizes WebSocket. In addition to Swagger-Socket, other protocols can also be implemented as an Atmosphere handler and used in those CXF and Olingo services.
