Genesis, A Real-Time Expert System for Network Control
A high level system design for GENESIS, a GEneric Network Expert System with Intelligent Simulation, is presented. GENESIS is a real-time expert system which will monitor and control the public voice telephone network. The design includes a human interface for display and user input, a realistic simulation of the network with expert heuristics to drive and test the expert system in real-time, an interface to required data bases and a blackboard for intermodule communications and control. The system is generic in that it was designed to reside above any network monitoring or data-collection system and to handle heterogeneous networks consisting of switching equipment from different manufacturers and a mix of product release levels. Key features of the design are flexibility and expandability to handle a growing network and changing needs.
An implementation of selected GENESIS features is also presented. This working prototype was written in C on a network of Sun Microsystems Workstations linked to an IBM PS-2. It handles major network problems including focused calling and facilities outages. Implementation issues and unique features are discussed. Experience in using and demonstrating the system to monitor and control a simulated network processing a peak traffic rate 300,000 calls per hour are presented. Performance of this prototype is extremely encouraging and indicates that much larger networks are feasible targets for this system design.
