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.

• 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。
