Part 5. Reliable Interaction

This part begins the journey into the domain of quality-of-service characteristics of Web service interactions with a discussion of reliable interactions. The figure that follows shows where this topic falls in the Web services stack.

Chapter 10, “Reliable Messaging,” discusses the WS-Reliable Messaging (WS-RM) specification. WS-RM defines protocols for establishing and maintaining a reliable interaction between a client and a service. It supports several different qualities of service, such as in-order and exactly-once delivery.

The second chapter in this section, Chapter 11, “Transactions,” discusses a venerable topic ...
