After running a simulation(using a simulator(QualNet)) of a simulated network I end up with ip stats stored in a database, I then extract the data to a csv file So now I have 750mb of raw network stats(time stamp, packet id, source ip, source port, protocol, etc). What are the common ways of analyzing large amounts of data like above, if you want to know things like packet loss, throughput, delay, congestion, etc.
Without knowing just what data you are interested in we can only give very broad and general replies.
Others will no doubt have their own preferred methods but what I do with that much data is to create Perl scripts to read the data directly from the database, using queries designed to read only those parts I am interested in for a particular report. The script would then produce output in a suitable form, most often as spreadsheets or charts.
The hardest part is not filtering the data and producing the reports. The hardest part is determining just what parts you do want to see. With that much data you have to filter it down if you want to make any kind of sense out of it.
