Most modern Cisco networking equipment has what’s called NetFlow technology built right in. A company called NetQoS has a software program called ReportAnalyzer which it claims is the only NetFlow monitoring software that has the ability to scale data from the world’s largest networks, and give network admins and engineers insight into the amount of traffic and how it is flowing through their network.
To the people who use this sort of technology, its use is already apparent. For those of us who are not network admins, this means the people in charge of your company’s network would have a better idea of how loaded down the computer network is getting. That way, if there’s too much load on the network, they can check their load-balancing systems and see if something is wrong. That way, they can provide better quality of service (or QoS) to you!
