Reliability enhancements for a Jini and JavaSpaces based network management system

A network management system software is prototyped using a service-oriented architecture with its core built using Jini and JavaSpaces technologies. The management system allows users to provision connections across multiple management domains. The system's functional modules are distributed to different management domains. Since the new management system is a distributed system, it imposes special requirements on system reliability. System reliability is improved by using lease-based resource and service sharing, transaction-based resource, concurrent access and persistent storage of resource information, and federation clustering. With these system reliability enhancements, the system is able to maintain its integrity even in the event of partial system failures.
