Symmetric distributed server architecture for network management system

Abstract

Flexible, highly scalable, and low-cost unified network management system architecture is very important for top-level system design. Symmetric distributed server architecture is proposed to design a unified network management system for huge scale telecommunication network. The J2EE multi-tier and distributed technology is applied to the distributed systems allowing parts of the system on separate computers located in different location. The message bus is used to provide a powerful way to structure unified large system and control the complexity in network. Proposed symmetric distributed server architecture is implemented in a unified NMS system including front-end server and back-end server constructed a matrix of server nodes. In case of updating a managed object, front-end server will locate the back-end where this object is managed and send updating request to this back-end. And every back-end will execute the core tasks on the sub-network assigned to it. The experiments and application have demonstrated that the architecture has good performance, reliability and is feasible and scalable for operation in current and future telecommunication network management. © Springer-Verlag Berlin Heidelberg 2003.
