-In this paper we describe the use of the　OPNET

simulation tool for modeling and analysis of packet data

networks. We simulate two types of high-performance

networks: Fiber Distributed Data Interface and

Asynchronous Transfer Mode. We examine the

performance of the FDDI protocol by varying network

parameters in two network configurations. We also

model a simple ATM network and measure its

performance under various ATM service categories.

Finally, we develop an OPNET process model for leaky

bucket congestion control algorithm. We examine its

performance and its effect on the traffic patterns (loss

and burst size) in an ATM network.
