- Simulation is a tool that can be used to assess functionality and performance of communication networks and protocols. However, efficient simulation of complex communication systems is not a trivial task. In this paper, we discuss modeling and simulation of bus-based communication networks and present the results of modeling and simulation of a multigigabit/s LAN. We used parallel simulation techniques to reduce the simulation time of the LAN and implemented both an optimistic and a conservative parallel simulation scheme. Our experimental results on a shared memory multiprocessor indicate that the conservative parallel simulation scheme is superior to the optimistic one for this specific application. The parallel simulator based on the conservative scheme demonstates a linear speedup for large networks.

- Today, new multi-Gbps LANs are designed to support a wide range of applications generating isochronous and nonisochronous traffic at arbitrary bit rates. The growing demand for high bandwidth networking, under increasing performance constraints, has posed fundamental challenges to LAN design and implementation. Three fundamental bottlenecks exist in a multi-Gbps LAN environment that must be handled in order to achieve optimal performance. These are: opto-electronic bottleneck, service bottleneck, and processing bottleneck. A novel architectural solution is proposed to open up these bottlenecks. Total network throughput of about 20 Gbps is achievable. Performance modeling, analysis and evaluation is reported for a class of Medium Access Protocols (MAC) for isochronous traffic. The performance results show good and very good performance for this solution.
