Toward Flexible Messaging for SOAP-Based Services

NaradaBrokering provides a messaging abstraction that allows it to provide message-related capabilities in a transparent fashion. These capabilities include message-based security, time and causal ordering, compression, virtualization of transport protocol and addressing, and fault tolerance related functionalities. NaradaBrokering - combined with further extensions to its existing capabilities - can also take advantage of the maturing of Web Service specifications to build very powerful general mechanisms to deploy and integrate it with general Web services. In this paper we describe our strategy to interface NaradaBrokering with Web services. The strategy described in this paper will allow new, and existing, applications built around the Web Services Framework to leverage capabilities offered by the NaradaBrokering substrate without changes to the service implementations.
