A Study on the Development of Simulator for Performance Evaluation of Traffic Control using UPC Algorithm in A TM Network

It is necessary that we should control the traffic to not only efficiently use the rich bandwidth of ATM network but also satisfy the users’ various requirements for service quality. However, it is very difficult to decide which control mechanism would be applied in real network because there are various types of ATM traffic and traffic control mechanisms. In this paper, a smart simulator is developed to analyze the perfonnance of a UPC(Usage Par neter Control) mechanism which is a typical traffic control mechanism. The simulator consists of a user interface that supports a menu-driven input form and a simulation program that is executed with the user’s input parameters. Especially, the simulator establishes more powerful and flexible simulation environment since it supports a more complex simulation applying various source tr fic to several different UPC mechanisms at the same time and allows an arbitrary user-defined traffic in addition to some well-known traffic.
