Like road traffic, it is essential to identify the cause of a slowdown to act and restore order. In the case of a computer network, the frustrating question that arises is: Who is monopolizing my bandwidth?
Why is the network so slow? Why is there no access to my e-mail? These are common questions users ask when the applications they use are not behaving as expected. As a system admin, network engineer or security engineer where should you start to troubleshoot such problems? One of the first checks that can be performed in this type of situations is to analyze the traffic of your network.
A Network Traffic Analysis tool lets you see the most heavily used devices, determine which users or applications use the most bandwidth and help you discover network usage trends. If you have a network monitoring tool, it is easy to know if the bandwidth usage of your network is high or if there has been a spike, but this does not mean that you can actually pinpoint what application is responsible of those spikes, that is the job of an NTA.
Is your business expanding or planning to expand? If the answer, is yes, it might be a good idea to find out if your current network infrastructure can sustain those plans. How can you find out? By being able to spot trends in your network using a Network Traffic Analyzer you will be able tell if you will need to upgrade your network or not. Being aware of how heavily used your network is at peak times will help you with the planning and management of your staff. This information is also important as it can help your team be more proactive and identify issues and bottlenecks before they happen.
