[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) W

[ns] Defining queing mechanisms

Hi! In order to implement queue mechanisms, i understand we can define it in when we define the links such as $ns simplex-link If i want to implement RED queue mechanisms, what should i write in queue_ type? $ns simplex-link ?? Regards, zoe

[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 need

[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] Trace Graph & convertor

Hi! I'm currently using trace convertor and trace graph. I can't seem to use trconvert.exe to convert my trace file into one that suits the trace graph. When i type Eg trconvert foreman, it doesn't recognise my trace format. FYI, my trace format is in this form, 1.122066 id 0 lost

[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 atta

[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] Implementation of WRED

Hi! Would need to enquire, how do we implement WRED into NS-2? Is there any websites that would help me if i want to implement WRED into NS-2? I can't seem to find any relevant ones. Thanks! zoe

[ns] PHB entry in DiffServ

hi! Some queries i would like to clarify; How do we define PHB entry values? How do we define code points? In the use of $dsredq setSchedulerMode Pri $dsredq addQueueWeights 1 5, how do we define the value "1 & 5" ? thanks! zoe

[ns] RED parameters

HI!! Would like to clarify some things with you. I tried to vary only the min and max thresholds for RED, so as to conclude the min and max behaviors, however, no matter how i change the thresholds, the results are the same. When i change the threshold values + the throughput of the channel

[ns] Packet Dropping

Hi! I've realised that even after defining a bottle neck link to be very small, there is still NO SIGN on packet dropping! How could it possible? where could have been the mistake?? Do enlighten me. 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
