The realization of work management system based on 2-dimensional distributed data driven architecture

A mobile communications network is comprised of a huge number of various NE (Network Element) distributed geographically. A system that supervises messages (including alarms) from NEs and controls NEs by commands to detect failures that occur in the network, is called EMS (NE Management System). We developed an EMS based on the D3A (Distributed Data Driven Architecture) that enables communications carriers to drastically reduce EMS TCO (Total Costs of Ownership) and to change external specifications flexibly and rapidly. A WMS (Work Management System) is a system that automates network management work such as plug-in work. When we implement a WMS based on D3A, to reduce work execution time is a significant challenge. In this paper, we explain how we have enhanced D3A by introducing the new idea of “Dimension” to it. The enhanced architecture is called D4A (2Dimensional Distributed Data Driven Architecture). We also describe the implementation configuration of the practical WMS and the results of performance evaluation.
