A Virtual PNNI Network Testbed
We describe our experiences designing and implementing a virtual PNNI network testbed. The network elements and signaling protocols modeled are consistent with the ATM Forum PNNI draft specifications. The models will serve as a high-fidelity testbed of the transport and network layers for simulation-based studies of the scalability and performance of PNNI protocols. Our models are written in the new network description language TeD which offers two advantages. First, the testbed design is transparent; the model descriptions are developed separately from, and are independent of, the simulation-specific code. Second, TeD is compiled to run with the GTW (Georgia Tech Time Warp) simulation engine which is supported on shared-memory multiprocessors. Therefore, we directly obtain the advantages of parallel simulation. This is the first complex test of the TeD modeling and simulation software system. The feedback from our experiences resulted in some significant improvements to the sim...
