Distributed Systems Management Based On OSI Environment: Problems, Solutions, And Their Evaluation

Abstract

Distributed Systems Managemen (DSM) will be significant issue within information network i n 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 communica t ion protocol in support of DSM, and,third,how to classify the management informations. I n this paper, to solve f irst problem described above, we introduce the basic structure of distributed network management system ( D N M S ) with intelligent facilities for efficient network management, and also especially give the concrete design o f system management application process which is an important element among them. A n d to overcome second problem, we propose the connectionless CMIP to accomplish fo r effectively manag ing the d is t r ibu ted m a n a g e m e n t system, and indicate its eff iciency; t h i s protocol i s available to negotiate among the managing systems, to handle the dynamic informations. To work out third problem, we introduce the connection criteria i n the h i e rarchy o f m a n a g e m e n t s y s t e m s , compare t h e conventional centralized systems management with the proposed distributed systems management, and finally evaluate the efficiency o f a suggested protocol dur ing cooperative negotiation among the managing systems.
