Knowledge-Based System Analysis and Control Defense Switched Network Task Areas

Abstract

A major activity during FY91 has been the design and implementation of a new Artificial Intelligence (Al) Utility architecture for the Integrated Workstation (IW) used by network management personnel at Defense Information Systems Agency-Europe (DISA-Europe). For the new utility, Lincoln has developed a revised IW Expert System (IWES) that no longer depends on the neural network component of the old architecture for problem detection. In addition, the new IWES has monitors that produce Alert messages when reported values from the network indicate significant departures from normal values recorded in a statistical database. The new architecture also allows expert site personnel to adjust the behavior of the system through new user interfaces. The IW, as installed in September 1990 and used throughout FY91, was subjected to operational test and evaluation at DISA-Europe in September 1991. The system, including the IWES. met user criteria and was recommended for acceptance as operational. Subsequently the new Al architecture was installed and demonstrated for site personnel. Substantial work has been done to enhance the value of the Lincoln Call-by-Call Simulator (CCSIM) as a trainer for IW operators. The CCSIM Top-Level Design Document was issued, and a draft document on the Common Channel Signaling implementation was sent to the Defense Communications Engineering Center for review. Preliminary simulations of the current Pacific Defense Switched Network were carried out. A component of DCEC FY91 tasking for Lincoln Laboratory is DRTV-funded expert systems development for the Defense Communication System transmission system control. This tasking is referred to as TRAMCON alarm integration, as in past reports. It had one major component in FY91. implementation of the TRAMCON .Alarm Interpreter, and one minor component, maintenance and extension of the TRAMCON Event Generator.
