摘 要: 针对多媒体实时业务需要提供特定服务质量的情况,给出了一种能够同时保证分组丢失概率和最大延时的自相似业务等效带宽计算方法。该算法采用分形布朗运动包络过程对自相似业务进行分析,通过增加最大延时约束条件,克服了原先基于分组丢失概率的有效带宽计算方法不能保证业务最大延时要求的不足。给出了具体计算公式,仿真实验证明了该算法的有效性。 Aimed at the quality of service required by real-time service, an effective bandwidth calculating method for self-similar traffic is presented to provide guaranteed packet loss probability and maximum delay. By using fractional Brownian motion envelope process and additional maximum delay constrain, the algorithm overcomes the shortcoming of those packet-loss-probability based methods which can not guarantee the packet maximum delay. The calculation formula is given out and the efficiency is validated through simulations.
