Voice over IP (VoIP) is gaining an ever increasing popularity. As such, it nowadays represents one of the most studied test applications in the performance evaluation of wireline and wireless networks. However, a sound performance analysis of VoIP communications should be carried out at the user level, by computing perceptive metrics like the Mean Opinion Score (MOS) or the E-Model.

In this site, you will find an enhancement to the popular Network Simulator 2 (ns-2) that allows a reliable VoIP user-level performance analysis to be carried out through simulation.

Installation

To install the patch, follow the instructions below:

1. download the ns-allinone-2.31 package from SourceForge

2. unpack the file that you just downloaded in your preferred location (let us assume the location is /usr/local). This will create a directory named /usr/local/ns-allinone-2.31

3. download the latest patch (let us assume that you downloaded the file in /tmp)

4. apply the patch, by executing the following command:

     cd /usr/local/ns-allinone-2.31/ns-2.31
     gzip -dc /tmp/ns2voip-2.31-070906.patch.gz | patch -Np1

5. compile the all-in-one patched ns-2.31, by executing the following command:

     /usr/local/ns-allinone-2.31/install

6. (optional) execute the following Tcl script example:

     /usr/local/ns-allinone-2.31/ns-2.31/voip/voip.tcl

The ns2voip patch includes an enhanced version of our ns2measure module, which is used to collect VoIP measures in an easy and efficient way. See ns2measure to get detailed instructions on how to use the ns2measure module and to download the related statistical utilities tools.
