I am using tracegraph to analyze trace data obtained by simulating 25,50 and 100
nodes in ns-2.
However, in each case I get the number of sent packets ( cbr) as a negative
number.
In order to verify the result I also obtained the cumulative sum of sent packets
from the graph and it turned out to be a big positive number. I have used 10
traffic connection pairs and I believe there should be some positive sent
packets.
I wanted to know which number is the correct one and why the numbers are
negative.
How can I get correct data for Total Bytes sent and TOtal Bytes received?

I really appreciate any prompt responses/suggestion.

Thanks,

Bandana
