Performance studies of a very high-speed LAN interconnected by a passive star coupler.

Optical local area network (LAN) design has become one of the most important issues in computer communications. In this thesis, we propose an ALOHA/Slotted-CSMA protocol for a very high-speed optical LAN interconnected by a passive star coupler. The network performance based on channel throughput and delay characteristics are analyzed and the numerical results are given. Comparisons are made with the other protocols based on the same network architecture. Detailed network modeling and modifications are given by using the software package BONeS (Block Oriented Network Simulator). A computer simulation program was developed to simulate the performance of the ALOHA/Slotted-CSMA protocol. Finally, results of the simulation and analytical studies are given and the comparisons and suggestions for future studies are made
