An implementation of customizable services with Java/ORB integration

The increasing size and complexity of managed networks requires flexible and distributed management services that are dynamically customizable. One solution is management by delegation, which can be implemented in a variety of ways. We propose a Java-based delegation mechanism, where customizable services are implemented using Java program fragments called MIBlets, which are downloaded to servers and operate on MIB data. We have developed a prototype version of a network management system based on Java and ORB, and have implemented the proposed delegation mechanism. Performance experiments show that MIBlets greatly reduce the network traffic and improve the response time.
