利用能够反映自相似特性的FBM模型,采用G/D/1排队模型研究了自相似性对网络性能的影响,讨论了在Norros给出的缓冲区溢出概率公式的基础下,FBM模型为输入时,网络平均排队延迟的解析公式.对理论分形流量和实际测量流量进行了仿真实验,验证了结果的正确性和有效性.
The FBM traffic model which holds self-similarity is used to study the performance of the G/ D/ 1 queuing model. Based on the buffer overflow rate given by Norros, the asymptotic analytic expression of the network average delay with FBM input is obtained. Theory fractional traffic and real measured traces are used to simulate experiment, simulation confirms the validity and efficiency of these results.
