[ns] Difference between red.cc and queue.cc

Hi! There is a question that we would like to seek your expertise on and that is the queue control. We understand and have found the queue control files available in NS-2 such as RED.CC, FAIR QUEUING.CC...and QUEUE.CC . However, there are certain areas that we don't quite understand. 1)

[ns] Implementation of queue mechanisms

Hi! I'm having problems with integrating new queing mechanisms into NS-2. After installing the patch files required, the response is segmentation error. Is there something that i should do or add on to? Another question that i have is, everytime we introduce something new to NS-2, do i

[ns] Patch Files

Hi! How do i create my own patch files for the changes i'm going to make in NS-2? Are patch files necessary? Thanks!

[ns] Integrating Error Models

Hi! Would like to ask, how do you integrate error models into the simulation? Eg MArkov model and random error models. Thanks!

[ns] Trace Files

Hi! I'm currently running a video trace through NS simulation, with the aim of getting an output trace at the end. However, it hasn't been successful. 1) What codes should i add to my tcl script to produce output trace file? 2) Should my input trace file be of a certain format? How do i

[ns] Trace files

Hi! Would like to ask, how do you generate a trace file from a raw video such that it is in a format that is recognized by NS-2? Thanks! Zoe

[ns] Buffer Size

Hi! how do you find the buffer size for the router when we implement RED? The problem we have right now is the router refuse to drop any packets no matter how we define the link. Pls help! Thanks zoe

[ns] RED queue

Hi! Without an error model, would there still be dropping of packets my RED parameters are set as minth threshold 5 max threshold 15 q_weight 0.002 maxp 0.1 markp 0.5 Thanks! zoe
