The NS2 simulation indicates that the advanced BLUE algorithm remain the low packet loss rate and show the better performance than BLUE in terms of queue size and link utilization,an estimate table about performance is presented,and the best way to improve the efficiency of algorithms is to select the performance index by genetic algorithm.

This paper simulates the packet loss rate of the wireless channel.

This paper analyzes and summarizes VANET channel laws, and indicates that there are three distributions of packet loss rate with distance on VANET channel.

Simulation results and analysis show that the architecture can decrease packet loss probability effectively and achieve reasonable .

This paper introduces the achievements of Internet end to end performance measurement technologies,including metric induced topology inference,delay inference,loss probability inference and bandwidth measurement.

Aiming to reduce system loss probability and to increase the switch efficiency ofcore node, this research probes into different switch efficiency of the OBS core nodeachieved by FDL and TWC respectively.

A novel model is proposed to construct widest available-bandwidth multicast tree under the constraints of end-to-end delay,delay variation and packet-loss rate,in which available bandwidth is really considered as prime metric.

A weighted model is proposed to construct quality-of-service multicast routing tree with widest available bandwidth paths un- der the constraints of end-to-end delay, delay variation and packet-loss rate, in which available bandwidth is really considered as prime metric.
