Concurrent network management system using distributed processing techniques

This paper proposes a concurrent network management system which can integrate various management applications in an efficient way. The proposed system provides both techniques and tools to attain concurrent execution of management applications in a distributed processing environment. For instance, each concurrently executed management application has its own communication module, named the virtual object, that interacts with other applications. The virtual object as a much enhanced version of the well-known RPC stub is capable of managing application connections and communicated data structures, or handling communication errors. The efficiency of integration is further enhanced through the use of a virtual object generator, which automatically generates the virtual object program codes. The effectiveness of the proposed system has been tested and confirmed in a newly developed experimental system that integrates our management applications such as network design, control, and diagnosis
