The topology and nodes are drawn to network  specification. The protocols are represented by using the Petri  Net graph with some extended features.  This  language  visually  of Petri  simulator is developed using Turbo Pascal Version 4. 0  under MS - DOS . The developed system can be used to  demonstrate the working of Token bus LAN and execution  Net.  This simulator has been designed for a maximum of 5 nodes  with fixed packet size and balanced load. Simulation tests were  conducted using both the protocols for performance evaluation  with respect to throughput and queueing delays for various  network conditions. The results have shown that with exhaustive  protocol, the average queueing delays are less compared to the  fixed time protocol. 0aLocal area networks (Computer networks)1 aNanda, Navnit Kumar, eChairperson1 aHuynh, Ngoc Phien,eExamination Committee1 aSkjesol, Trond, eExamination Committee2 aGovernment of Japan, eScholarship Donor2 aAsian Institute of Technology.tResearch studies project report ;vno.
