Performance Evaluation of Interconnected Heterogeneous Local Area Networks

A simulation model for the interconnected local area networks (LAN's) is presented in this report. The interconnected networks consist of token ring, fiber distributed data interface (FOOl) network and carrier sense multiple access with collision detection (CSMNCO) network. In the interconnected networks, the local users on the token ring send intraor inter-network packets. The inter-network packets are transmitted to CSMNCD network via gateways and FOOl network. In the meantime, the local users on the CSMNCO network generate intra-network packets. The model focuses on the end-to-end delay between two end users on token ring and CSMA/CD network.
