Abstract

Time-parallel simulation defines a methodology thatcan be applied to certain specific simulation problems. Inthis paper, we present a time-parallel approach for tracedrivensimulation of the CSMA/CD protocol. The"memoryless" property of the physical system undermoderate traffic loads allows for efficient time-parallelsimulation. We also present two optimization techniques:the estimation of idle points and the incremental fix-upcomputation. The former can improve the probability thata subtrace begins with a known initial system state. Thelatter can speedup the fix-up computation that is requiredwhen the estimation of the initial state is incorrect.
