[ns] how to trace average RED queue dynamics per flow

2008-04-21 Thread Soo-Hyun Choi
imagine there are 8 TCP and 8 TFRC sources sharing the same bottleneck (RED queue). i would like to draw the average red queue _per_ flow (not aggregate). i have used similar to the following tcl script in my simulation script, but it only traces the aggregate (8 tcp + 8 tfrc) average red

You could do ./configure --enable-debug at the ns-2's top directory, and then try make again. It will enable assert() funtion. Soo-Hyun On 4/16/06, Dhammika Pathirana [EMAIL PROTECTED] wrote: Hi Vinod, This is because NDEBUG is defined in the makefile. Replace is with DEBUG to enable

Hi, First, in general, CBR is used for UDP traffic, not with TCP. You should be able to tell the specific reason why you use CBR over TCP. And the question you asked is also dependent upon a bottleneck link speed and a bottleneck queue size. If the dely-bandwidth product is larger than the CBR

The instantaneous RED queue size shouldn't grow beyond the actual RED queue size, and the average RED queue size shouldn't grow beyond the maxthresh. You may want to check your parameters again. On 3/7/06, ben [EMAIL PROTECTED] wrote: Hi ns users, I some doubt about the RED Queue. I run a

You need to set the queue size by modifying the following two lines. $ns queue-limit $node_(r1) $node_(r2) 100 $ns queue-limit $node_(r2) $node_(r1) 100 On 3/7/06, ben [EMAIL PROTECTED] wrote: Hi Soo-Hyun Choi, I attached the output of the xgraph in ps format. 1. red.ps - red.tcl run

You will need to change max_p and q_weight as well. Sally's recommendation for the max_p is to set it as twice as the loss rate. Soo-Hyun On 3/2/06, #LIM XIAOWEI# [EMAIL PROTECTED] wrote: HI!! Would like to clarify some things with you. I tried to vary only the min and max thresholds for

I think you don't seem to have Tcl/Tk development packages for Debian. You could probably do sudo apt-get install tcl8.3-dev tk8.3-dev, and then try again ns-2 installation. -SH On 1/11/06, Leonardo Maccari [EMAIL PROTECTED] wrote: I'm trying to install ns2 2.29 (tried 2.28 too) on debian
