The PQM and AQM Implementations and Comparison Based on NS2

Liang Pan(Electronic Information Dept.of Aba Teachers College,Pixian 611741)  
Queue management network congestion control mechanism is an important technology that is currently divided into passive queue management(PQM)and active queue management(AQM),the former in congestion occurs when a passive use lost tail strategy(DropTail) discards all new to the grouping,which changes depending on the queue length for early packet loss to minimize and avoid congestion.In order to compare PQM and AQM,research to their classic algorithm DropTail and RED,for example,in NS2 environment implements two mechanisms of simulation and analysis,pointed out the respective advantages and disadvantages,to further research on improving the congestion control algorithm.
