I've searched in the forums and mailing lists, some people asked whith the same problem, but no one gave an usefull answer.<BR/><BR/>Im trying to implement a SwitchQueue model, inherited from Queue, but right now is too much for me.<BR/><BR/>Im sure that someone has already solved this problem.<BR/><BR/>Can you please, point me to some direction or tell me how to solve this matter?<BR/><BR/>my email is: pelayor@gmail.com<BR/><BR/>Thanks in advance.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-21339912.post-30016800098628785892008-02-03T11:07:00.000+09:002008-02-03T11:07:00.000+09:00Hi, i am a final year student of ECE department. I...Hi, i am a final year student of ECE department. I am using NS-2 for my final year project. I will be grateful if you can please clear my doubts: i use UDP agent and CBR application. i have used the command "$cbr1 send $packetsize1" for sending a single packet. It works fine for me for the first time. But when this is put in a 'for' loop, the receiver doesn't receive the subsequent packets. It just receives the first, all the other packets are lost. I have used, LossMonitor as the sink, to monitor the loss. The for loop is: <BR/><BR/>for {set i 0} { $i < 200 } {incr i} {<BR/><BR/>set dc1 [expr $dc1 + $quantum]<BR/>set dc2 [expr $dc2 + $quantum]<BR/>set dc3 [expr $dc3 + $quantum]<BR/><BR/>if {$dc1 > $psiz1} {<BR/>$cbr1 send $packetsize1<BR/>set dc1 [expr $dc1 - $psiz1]<BR/>}<BR/><BR/>if {$dc2 > $psiz2} {<BR/>$cbr2 send $packetsize2<BR/>set dc2 [expr $dc2 - $psiz2]<BR/>}<BR/><BR/>if {$dc3 > $psiz3} {<BR/>$cbr3 send $packetsize3<BR/>set dc3 [expr $dc3 - $psiz3]<BR/>}<BR/><BR/>}<BR/><BR/>Can you please help me in this regard?
