Modeling Atm Networks In A Parallel Simulation Environment: A Case Study

This paper describes our experience with implementing an Asynchronous Transfer Mode (ATM) network simulator in the high-level sequential programming language SMURPH [Dobosiewicz and Gburzynski 93], and then porting it to SimKit---a parallel simulation tool offering a C++ interface to a shared-memory implementation of the well-known Time Warp [Jefferson 85] concept. The work was undertaken as part of the TeleSim project, which aims to build a set of multi-purpose highfidelity ATM simulation tools for execution in sequential and parallel environments. 1 Introduction ATM is a connection-oriented packet-based switching technology designed for high-speed networks. Designing a simulator for ATM networks is not a well-defined task, because ATM is a networking concept rather than a single networking solution. Owing to the lack of a complete specification, our network model is made up of two distinct components with different requirements: a model of the generic ATM network hardware, i.e., the..
