Abstract
In some B-ISDN applications running on ATM networks (e.g., for audio/video connections), the occasional loss of a single ATM cell may not affect the user's perceived QoS requirement. However, the QoS may be degraded due to the loss of a multiple ( consecutive) ATM cells. As the event of consecutive cell loss is (typically) rare, its probability cannot be estimated efficiently using standard simulation. In this paper we propose a fast simulation method, based on importance sampling, to efficiently estimate the probability of a rare consecutive-cell-loss event. As an example, we consider a queueing model of the Leaky Bucket source policing algorithm, operating in a bursty traffic environment. We present empirical results to demonstrate the validity and effectiveness of our fast simulation method.
