Abstract: Context-based routing of requests in a service-oriented architecture (SOA) is achieved by using context information received from service providers to make routing decisions. Service providers publish information about their context on a publish-and-subscribe channel. A router (e.g., a JBI normalized message router) subscribes to the channel to receive the context information, and may store the context information in a context repository. A consumer issues a service request specifying a context, and the router uses the context information received from the service providers to select the service provider that best satisfies the context. The request is then routed to the selected service provider.

Abstract: A method and apparatus for dynamically discovering and communicating data in a communications network are described. A broker in a communications network receives a communication from a first service provider over the communications network, the broker comprising a metabroker and a service broker. The metabroker communicates messages to the service broker within defined time intervals to provide the service broker with any updated information about topics including a first topic. The broker sends information about the first topic to a first service consumer over the communications network within a first time interval from receipt of the communication comprising data about the first topic, and establishes peer-to-peer communication between the first service provider and the first service. The broker receives further communications about topics from multiple service providers over the communications network, and sends further data about to the first topic to the first service consumer.
