Compare the three different queuing algorithms Drop tail, Stochastic fair queuing and Random early detection. determine which queuing algorithm gives the least lost packets for the three different queue lengths

i have uploaded tcl scr ipt program for creating nodes and implementing droptail buffer mechanism

不同队列管理机制：DropTail和RED对系统吞吐率，时延，丢包率的影响。-Different queue management mechanisms: DropTail and RED on the system throughput, delay, packet loss rate.
