摘　　要：重点研究了排队系统中自相似业务带宽分配和接纳控制.根据分形布朗运动包络过程推导出了有效带宽的计算公式,并且推导出了考虑信源内增益和信源间增益的接纳控制算法.通过仿真研究了有效带宽随缓存区、Hurst系数的变化关系,接纳域随缓存区、Hurst系数的变化关系.证明了基于FBM下的资源分配比传统的模型更有效.The bandwidth allocation and admission control of a self-similar traffic input queue system are investigated in this paper. The formula of effective bandwidth is derived based on fraction motion envelope process and admission control algorithm which is account for multiplex gain from both ＂in the source＂ and ＂across the source＂ is proposed the variation of effective bandwidth and admission regions with the parameters of Hurst index and buffer size is investigated through simulation. It proved that resource allocation based on FBM is more effective than which based on traditional model.
