Abstract: Disclosed are methods and apparatus for managing services within a computer network. In one embodiment, a message interchange network for exchanging application-level messages between services, which are located outside the message interchange network, is provided. At the message interchange network, a plurality of application-level messages, which each specify which one or more receiving services are to receive the each application-level message, are received. Each received application-level message is forward towards the one or more receiving services. Correlation information regarding each application-level message that is received into message interchange network is retained. The application-level messages are sent between pairs of the services, and the retained correlation information for each application-level message pertains to each application-level message and any other application-level messages related to the each application-level message.

Abstract: Disclosed are methods and apparatus for effectively correlating messages sent between services. In general, a message interchange network is configured to manage the use of services by remote entities or services within a computer network. In general terms, correlation information is stored for each message. The correlation information includes information for correlating each message with a specific call between two services and a specific session between two or more services.
