1.ns simulate wired-measure.tcl to generate record files


2.sd_udp list 550 items


3. open rd_udp
542 packets collected(543 lines)


8 packet loss = 8/550 = 1.45%

4. packet delay time


依照課本完成圖形，到電腦打開那張gif有發現打不開的情形，發現是cygwin佔用那張圖片
把cygwin關掉候，就可以順利打開了

5. measure jitter




6.udp throuput measure
