Conservative parallel simulation of ATM networks

Abstract

A new Conservative algorithm for both parallel and sequential simulation of networks is described. The technique is motivated by the construction of a high performance simulator for ATM networks. It permits very fast execution of models of ATM systems, both sequentially and in parallel. A simple analysis of the performance of the system is made. Initial performance results from parallel and sequential implementations are presented and compared with comparable results from an optimistic TimeWarp based simulator. It is shown that the conservative simulator performs well when the "density" of messages in the simulated system is high, a condition which is likely to hold in many interesting ATM scenarios.

GloMoSim

“…Much of the existing research in parallel network simulation has been done in the context of wired networks that include ATM networks, LAN simulators, and interconnection networks for parallel computers [3,7,9,14]. Relatively little research has been done to evaluate the feasibility of parallel simulation of wireless networks.…”

Modeling and Parallel Simulation of Large ATM Switch Fabrics

“…Sequential simulation of large and complex systems, however, is often computation intensive and requires large computer memory. Parallel Discrete-Event Simulation (PDES) techniques have been successfully used to reduce the execution time of CPU intensive simulations [2][3][4]. In this paper, we discuss a specific application of ATM technology and the need for advanced simulation techniques.…”
