摘要

This paper describes a Publish and Subscribe capability developed under the Air Force Research Laboratory's (AFRL) Joint Battlespace Infosphere (JBI) project. The paper will give a brief description of the JBI and it's core service components of publish, subscribe and query. A detailed description of the Pub/Sub system design and implementation will then be given describing how and where Java, Jini, and XML technologies were used to describe information objects, match subscribers to appropriate dissemination nodes, and disseminate information objects to subscribing clients. Finally we describe a number of applications that are currently using the Pub/Sub capability.
