Importing video traffic into OPNET

Video Traces

Video Trace files available at

Arizona State University[1]
MPEG-4 and H.263 Video Traces for Network Performance Evaluation[2]

Processing Video Traces

The video traces data required pre-processing before they could be imported into OPNET Modeler video conferencing application (VCA) traffic data. The frame sizes need to be extracted from the video traces, then converted from bits to bytes. Saving the final result as a .csv compatible format file.

For Verbose Trace File use this shell command line to do the extraction:

awk '// {print $4/8}' video_trace.data > traffic_trace.csv

For Terse Trace File use this:

awk '// {print $2/8}' terse_trace.data > traffic_trace.csv

OPNET Setup

From the Object Palette insert an "Application Config" node

Next, edit the attributes of the Application node. Under Application Definitions->Description select "Video Conferencing". Choose "Edit"

Enter the video's frame rate into "Frame Interarrival Time Information" field.

Select "Edit" for Frame Size Information (bytes)
