摘要

A mobile communication network is composed of a tremendous number of diverse network elements (NEs), which are distributed over a wide geographical area. The system that monitors messages (including warnings) from the NEs and controls the NEs is called the network management system (NMS). Since the NMS is required to handle a large number of messages, it has been implemented with expensive large-scale UNIX servers. Thus, the communication carrier is forced to invest a large amount in the hardware and middleware of the NMS. Another problem is that the carrier must follow the vendor strategy, such as migration to next-generation hardware and OS upgrades. The authors have devised the organization hierarchy agent model (OHAM), in which the external specification of the NMS is represented at the data level as agent behavior, making it possible to add new external specifications quickly and flexibly to the NMS as functions. This paper describes the organization hierarchy mobile agent model (OHMAM), which achieves high processing capacity by upgrading the OHAM agents to mobile agents that move rapidly between small-scale IA servers. A practical commercial system was formed by using the proposed model, and the results of its basic performance evaluation and reliability evaluation are presented in this paper. In the implementation of the proposed model, IA servers, which are inexpensive and readily available, are used as hardware. Open source software (OSS) such as Linux/Java VM/Post-greSQL is actively used as OS/middleware. Thus, the total cost of ownership (TCO) of the NMS can be greatly reduced.
