Abstract:
The introduction of the Asynchronous Transfer Mode (ATM) is currently being propelled by the need for fast data communication in public and private networks. ATM is the switching and multiplexing technique employed for ISDN. In this dissertation a simulation tool is developed for Asynchronous Transfer Mode (ATM) networks to analyze the behavior of ATM networks. The developed tool is a GUI based that gives the user an interactive modeling environment. With this tool the user may create different network topologies, control component parameters, measure network activity, and log data from simulation runs. In this simulator we include some components which are necessary to formulate an ATM network like an ATM switch, a Broadband Terminal Equipment (BTE), (may be an ISDN node like Host computer, Workstation etc.), Some ATM traffic Applications like CBR (Constant Bit Rate), VBR (Variable Bit Rate), ABR (Available Bit Rate) and TCP/IP based traffic etc., and Physical connection link to connect various components like switch to BTE, switch to switch etc., this may be Optical Fiber, Coaxial Cable or Copper wired.
This dissertation aims to study of the various kinds of network configurations with ATM as a backbone and the results of various parameters of network components like throughput, delay, link utilization at various network configuration, size of various ATM application queues, and some congestion related parameters also
