摘要

采用在线测量的方法计算业务流的统计特性估计其突发水平以便选择合适的业务流模型。为了保障业务流的统计QoS，基于选定的业务流模型，通过有效带宽和有效包络的转换定理，获得多分形和自相似业务流的有效包络。然后，采用统计网络演算获得QoS参数进行接纳控制决策，并且通过选择接纳时机减小接纳控制本身对QoS的影响。仿真结果表明该算法能够准确地选择流模型，满足流模型的统计延迟要求，提高带宽利用率。

Abstract

Statistical properties of the traffic were calculated to estimate the burst level through online measurement for selecting proper traffic model.In order to guarantee traffic QoS

the effective envelope of self-similarity and multiracial traffic was derived using the transformation theory between the effective bandwidth and effective envelope.Then

QoS parameters were obtained using network calculus to perform admission decision;furthermore appropriate admission time was chosen to reduce the proposed algorithm’s impact on QoS performance.The simulations prove that the traffic model can be selected accurately

statistical delay can be ensured and utilization efficiency of network is improved.
