A Visual Basic (VB) script was written to do some analysis on several different data files at once
as well. This allows for complete test set data to be calculated once and imported in one easy
step.
The Omnicor software has been installed and tested on the Compaq laptop and the IBM Laptop.
Figure 3.4 is a diagram of the IP Traffic measurement environment. As is evident in the figure
there are many parameters that can be set for testing purposes. The number of packets can be
set, as well as the payload of the packets. A random packet generator is built into the software.
By setting the packet sized to a fix amount and then also setting the throughput the interpacket
delay is automatically set to achieve the throughput with the packet size requested. This facility
even works when pause and resume frames are being sent. Although IP Traffic has the ability to
record the data as it is received, this function proved to provide a huge overhead that limited the
throughput in the system, so it was not implemented during testing. If this function had not
lowered the throughput so significantly the recorded data could be compared to the source data
and bit error rate analysis could have been done.

type of data to be transmitted.
