Abstract:

TWO LOCAL AREA NETWORK (LAN) STANDARDS, IEEE 802.5 AND ANSI X3T9.5 FFDDI, HAVE SEEN INCREASED USE AMONG BOTH MILITARY AND INDUSTRIAL USERS ESPECIALLY FOR APPLICATIONS WHICH HAVE TIME-CRITICAL PERFORMANCE REQUIREMENTS. THESE STANDARDS ARE THE BASIS OF PROPOSED NAVY STANDARDS, DESIGNATED SAFENET-I AND SAFENET-II. IN THE EVENT OF A FAILURE, A KEY PERFORMANCE PARAMETER ESSENTIAL TO DESIGNERS OF TIME-CRITICAL APPLICATIONS IS THE CAPACITY OF THESE PROTOCOLS TO RECONFIGURE THE NETWORK IN A PREDICTABLE AMOUNT OF TIME. CONSEQUENTLY, THERE IS A NEED TO DEVELOP A HIGHLY ACCURATE TOOL FOR ANALYZING AND THEN OPTIMALLY FINE-TUNING LOCAL AREA NETWORK RECONFIGURATION TIMES IN RESPONSE TO VARIOUS FAILURE SCENARIOS. THE ULTIMATE GOAL OF THE PROPOSED RESEARCH IS THE DEVELOPMENT OF SUCH A TOOL. THE TOOL WILL CONSIST OF A FIMULATION MODEL IMPLEMENTED ON A PARALLEL PROCESSOR AND A SIMULATED ANNEALING OPTIMIZATION TECHNIQUE. THE MAJOR INNOVATION IN THE PROPOSED RESEARCH IS THE UNIQUE INTEGRATION OF GRAPHICAL REPRESENTATION OF NETWORKS, DISTRIBUTED SIMULATION USING ADAPTIVE TIME WARP, AND A TECHNIQUE FOR DETERMINING SETS OF NETWORK PARAMETER VALUES WHICH MINIMIZE LAN RECONFIGURATION TIMES. SATISFYING TWO TECHNICAL OBJECTIVES WILL DEMONSTRATE THE TECHNICAL FEASIBILITY OF THE PROPOSED APPROACH: (1) DESIGNING A SIMULATION MODEL THAT ACCURATELY AND EFFICIENTLY ESTIMATES THE NETWORK RECONFIGURATION TIME IN RESPONSE TO VARIOUS TYPES OF NETWORK FAILURE SCENARIOS AND (2) DEVELOPING A TECHNIQUE THAT GUIDES THE NETWORK DESIGNER TOWARDS A DESIGN THAT MINIMIZES RECONFIGURATION TIME SUBJECT TO VARIOUS CONSTRAINTS.
