OK, http://nile.wpi.edu/NS/ → Example Utilities → Trace Analysis Utilities. Using : $ sudo apt-get install tcsh $ chmod +x jitter.sh $ ./jitter.sh out.tr * May work ? with some files `out.tr´. * Be aware that only files by name "out.tr" can be used : $ ln -s <any-other-name>.tr out.tr ( Or : you can make a dedicated "jitter.sh" >>> new.jitter.sh, i.e. edit line 3 to your-file.tr : cat your-file.tr | grep ... ). The file jitter.sh is also present in awk_scripts_11.2014.tar.gz https://drive.google.com/file/d/0B7S...ew?usp=sharing Code:
#! /bin/tcsh -f |

Could be the script `jitter.sh´ just don't work at all with any file.tr ? Or that it might work with a particular formatting of a trace file ? "jitter" : Google .. ns2 measure jitter .. https://www.google.com/webhp?hl=all&...measure+jitter → Example ... http://trungtm.wordpress.com/2007/07...-applications/ → "How to measure packet loss rate, jitter, and end-to-end delay for UDP-based applications". - |

Ok i downloads this files and i executed think you
but there is a problem , always show me there is no paquet loss = 0 so i have look to my file.tr i didn't found any dropped paquets ( no letter "d" in any ligne in this file.tr ) Is that mean that the problem is in the topologie from the begining or what ?? Note : I execute the NAM file and i see that there is a transfer of flow paquet Also forcalculate the delay or the jitter , i have an error message " division by zero attempted" i think that in the jitter.awk it does not count the send delay and the receive delay so it takes zero and when it do the division opperation this message was showen Please can you help me to correct this errors ?? |
