A group of leading IT vendors, consisting of Fujitsu Limited, Hitachi, Ltd., NEC Corp, Oracle Corp., Sonic Software, and Sun Microsystems, today announced the publication of the Web Services Reliability (WS-Reliability) specification working draft (see links below). By providing a fundamentally more reliable transport infrastructure, WS-Reliability will help accelerate adoption of Web services, making them relevant for an even wider range of enterprise application and integration challenges. WS-Reliability is a specification for open, reliable Web services messaging including guaranteed delivery, duplicate message elimination and message ordering, enabling reliable communication between Web services. The reliability features are based on extensions to the Simple Object Access Protocol (SOAP), rather than being tied to the underlying transport protocol. The specification will allow a variety of systems to interoperate reliably in a platform- and vendor-neutral manner. Following collaboration on the specification draft, the companies plan to submit WS-Reliability to a standards body on a royalty-free basis. Reliable message delivery means the ability to ensure delivery of a message with the desired level of quality of service. Some examples of this quality of service level for message delivery are:
The WS-Reliability specification defines a method for exchanging SOAP based messages with a particular level of service, no duplicates, and a particular message order. For more information on WS-Reliability:
