REST as an alternative to WSRF: A comparison based on the WS-agreement standard

WS-Agreement and WS-Agreement Negotiation are specifications that define a protocol and a language to dynamically negotiate, renegotiate, create and monitor bi-lateral service level agreements in distributed systems. While both specifications are based on the Web Services Resource Framework standard, that allows using stateful SOAP services, the WSAG4J reference implementation additionally provides a RESTful service implementation of the same operations. This paper evaluates the performance disparity between the standard conformable and the RESTful implementation of WS-Agreement and WS-Agreement Negotiation. © Springer International Publishing Switzerland 2014.
