Enhancing Jini for Use Across Non-Multicastable Networks
Abstract
Distributed heterogeneous systems are being increasingly used to execute a variety of large size simulation and computational problems. Resource management is one of the most important issues in building such systems. Recently, Sun introduced the Jini connection technology for building plug-and-play networks of resources. Jini relies on multicasting across the network for its internal protocols. However, in a distributed environment, such as the one under consideration here, multicasting may not be supported across the subnets for various reasons. Described in this paper are enhancements to Jini required to use it for building a middleware resource management system in a distributed environment that does not support multicasting. In particular, introduced is a lightweight service, called the Tunneling Service, which tunnels multicast messages across the subnets. The mechanism has been implemented and used successfully to tunnel messages between subnets in a single domain and also between different domains. Described in this paper are design choices and implementation of the system.
