Thanks for the help everyone. But there seems to be a problem. I can't graph this data in Excel! There are more rows than Excel can handle. Also, the data I managed to graph on Excel did not look too good.
I have two questions:
Is there a way to condense the data? Like add up all of the bytes for every 10 seconds? The time value for each aggregate will be the first second in the 10 second grouping.
Right now, there are a lot of packets which are sent at the SAME time.
Also, is there another graphing tool that will work well with large data sets? I was thinking maybe GNU plot.
