An event notification framework based on Java and CORBA

Event notification is essential in network management. Many components in a distributed NMS need an event notification mechanism, and so an event notification framework is expected to facilitate the development of the components. CORBA is a promising platform to build such a framework, but its performance is not sufficient for monitoring large-scale networks. This paper proposes an event notification framework that has high performance and customizability. The framework is based on Java and CORBA, and has customization points at which event handling capabilities can be added. Java gives the framework flexibility in the sense that event handling capabilities call be added and replaced dynamically by using downloadable Java programs. High throughput of more than 1000 events per second has been achieved by event batching
