Modeling of standalone and networked ATM switches (N-AtmSim) using discrete event simulation with TCP/IP sockets

Simulation determines the system behavior prior to design and implementation phase. Simulation of ATM switch has various complexities to be handled; simulating the hardware parallelism is one of them. We have developed an ATM switch framework (ATMSim), which provides a basic framework for future modules to be plugged in. In our current implementation, we have considered the data plane only. Our framework would be useful in the sense that it provides a unique ATM simulation architecture, which can be utilized by the academicians, institutions and the industry for experimenting over an ATM network and in the future to simulate other components of the ATMSim is "PROTOCOL AGNOSTIC" in the sense that, it can be converted to any L2/L2.5 protocol switch (viz. MPLS, gigabit Ethernet switch). The switch fabric used, is a library, rich with features and supporting different user defined configurations. The pre and post processors are also in the form of the library, which is highly flexible.
