基于确定性网络演算理论推导了使用自相似业务作为输入时该GPS系统的缓存队列长度、延迟、延迟抖动以及有效带宽等性能确定上界模型。数值结果表明

基于分形整形器的GPS系统性能确定上界模型对自相似业务具有较好的性能。

Abstract

In order to get exact bounds problems encountered in networking with self-similar input traffic

a fractal regu-lator was introduced into the ingress of a generalized processor sharing（GPS） system for regulating the self-similar traf-fic

and a model was presented based on fractal regulator and GPS.The deterministic bounds on queue length

delay

de-lay jitter and effective bandwidth of the system with self-similar input traffic were derived using network calculus.Nu-merical simulations demonstrate that the bound models of a GPS system based on fractal regulators using network calcu-lus are suited for the networks with self-similar input traffic.
