Network Traffic Analysis

By smjuthani ·
Sir, I would like to know which software detects a computer(s) on a network that generates too much data requests, thus saturating whole network?

Hi.... before looking at the computers (ethereal can help there.... www.ethereal.com for a freeware application that takes some effort to use but can help identify the IP addresses of users..... Also in the free world - Look@Lan may help you....) you may want to consider the settings of the routers and switches..... some Pro-Curve switches have a default limit on UDP traffic of 400 transactions per second... some client server apps are very heavy on UDP traffic and can exceed this figure - if they do the packets are just binned - lost for ever!

Also look at the port settings either end of LAN/WAN to ensure that the network latency is not too high..... When you do analyse the problems with something like Ethereal you can see what the content of many of the packets actually is. Often you can find that there are unnecessary packets being sent - I have seen quite a few applications that have debug messages flying backwards and forwards that have served their purpose in development but that have not then been removed from the code.

Some thoughts there - good luck!

If you have installed the ISA server, you can configure this to e-mail you the network and web traffic. From this report you can identify by IP address the top web or network users, with they traffic details.
