Performance of Distributed Simulation Using Multiple Segment Ethernet Communication Networks
Abstract
This paper presents the work with the generalized Petri net (GSPN models of a simulation network similar to SIMNET, a distributed system of training simulators connected over an Ethernet local area network. In contrast to isolation models, these models use a global approach to represent the details of the interaction among the stations over the network. In our first GSPN model, sixteen chains are used to capture the state of transmission for the sixteen attempts allowed for each node. The 'frame transmitter process is accurately represented in this model by keeping track of the individual attempts separately and using the correct backoff delay distribution for each attempt. Two modification of this model are obtained by introducing approximations that allow the execution of networks with a larger number of nodes while maintaining a good degree of accuracy. Results of important performance measures (e.g., frame loss rate due to excessive collision count) obtained from the three models are presented and compared.
