Abstract
Modern applications of computers such as video-on-demand require real-time response and need distributed implementations. Object Request Brokers(ORBs) [9] provide a solution to the distribution problem by allowing method invocation on remote objects. However, mere remote method invocation is not enough in a distributed setting: application programs also require features like fault-tolerance and load-balancing. Integrating all possible functionality into an ORB would result in a complex, monolithic program, so we need a modular architecture for ORBs. In this paper, we show how reflection enables the construction of a composable ORB that can be customized to support new feature.
