    The problems encountered in decentralized control are identified, and an informal description is given of how expert-systems techniques can help in addressing some of them. A model of a distributed system is given, the characteristics of a distributed intelligent resource manager are discussed, and the architecture of an expert manager currently being built is described.<> View full abstract»

    A project is described that has two goals: to explore the use of expert systems techniques for developing advanced operation support systems and to build a useful tool to assist the operators of the Canadian National Datapac network to cope with the rapid growth and evolution. Progress in developing and evaluating an advanced prototype system, DAD (Datapac Advisor), is reported. The prototype's environment and each of its functional components are described. The knowledge based design techniques used are highlighted, and the testing methodology and the results of a technical trial are described. Key findings are summarized, and their significance for the development of future network operation support systems is discussed.<> View full abstract»

    The authors present SIMNETMAN, a network simulator, and discuss its role in exploring the utility of expert system technology for network management. SIMNETMANs companion system, NETMAN, is a collection of rule-based experts for network management. SIMNETMAN provides the user interface for NETMAN by allowing the experimenter to construct the network to be simulated, to specify the experiments, and also to modify the rules that comprise NETMAN, SIMNETMAN simulates a packet-switched network and actually conducts the experiments requested by the user. An overview of the system is presented, followed by a discussion of the implementation problems. The simulation capabilities of SIMNETMAN and preliminary performance results for the NETMAN/SIMNETMAN system are reported.<> View full abstract»

  • Designing expert systems for real-time diagnosis of self-correcting networks

    The authors discuss design issues that they have encountered during an investigation of expert systems for network management that they believe to be generic to the real-time diagnosis of self-correcting networks. By real-time they mean that the diagnostic system must keep pace with a dynamic process, that is, the flow of alarms from intelligent network elements. The objective is to present the operator with a set of recommended actions rather than large volumes of raw alarm data. They outline the general requirements of such a system and then suggest how each can be addressed using an expert-system approach.<> View full abstract»

    The authors present the architectural principles and generic concepts that they have identified in their chosen sales domain and subsequently modeled in the expert network selector (ENS), ENS is a knowledge-based tool that is currently being developed to assist Bell Canada networks-sales agents, who may not possess some of the in-depth technical knowledge required to operate conventional design tools, in their daily operations. It uses a multiparadigm knowledge representation scheme to translate a customer's communications and networking requirements into fully-configured solutions. ENS is implemented in Prolog and combines frames and rules.<> View full abstract»
