摘要
由于因特网越变越大,越来越复杂,但网络的监控管理又不能完全依靠路由节点监测链路的性能参数,QoS推测成为一个新的研究热点。在MFMM模型的基础上提出了一种方法,能够只根据测得的端-端的时延数据,推测单一测量路径上各链路的时延密度函数。文中给出了仿真结果,并分析了算法的有效性和进一步的研究方向。
Intemet is becoming more complex than ever. It results in the difficulty of managements based on the parameters monitored by the routers in existence. Intemet inference is a new research field. Based on the MFMM （Mixed Finite Mixture Models）, this paper proposes a method that can estimate intemal link delay distributions along a single measurement path from end-to-end measurements. Simulation results are given. This paper also analyzes the efficiency of the method and further researches.
