Distributed Systems Management based on OSI environment: Problems, solutions, and their evaluation

Distributed Systems Management (DSM) will be significant issue within information network in order to increase the high reliability and to improve the flexibility of network management. The OSI management model has several problems. The key problems are that it does not fully address the problem of, first, how to define system architecture suitable for distributed management environment, second, how to develop communication protocol in support of DSM, and, third, how to classify the management informations. In this paper, to solve first problem described above, we introduce the basic structure of distributed network management system (DNMS) with intelligent facilities for efficient network management, and also especially give the concrete design of system management application process which is an important element among them. And to overcome second problem, we propose the connectionless CMIP to accomplish for effectively managing the distributed management system, and indicate its efficiency; this protocol is available to negotiate among the managing systems, to handle the dynamic information. To work out third problem, we introduce the connection criteria in the hierarchy of management systems, compare the conventional centralized systems management with the proposed distributed systems management, and finally evaluate the efficiency of a suggested protocol during cooperative negotiation among the managing systems.
