NetFlow Traffic Analyzer

Network bandwidth isn't something that you can physically see, so it can be hard to tell that you don't have enough. Usually, you have to wait until you get complaints from users. NetFlow Traffic Analyzer tells you what is going on with your computer network, and allows you to answer questions like: What applications are consuming all my bandwidth? How much bandwidth is actually being used? Is there a user or a department that is hogging all the bandwidth? What kind of traffic are the computers on my network generating? NetFlow Traffic Analyzer enables you to answer all these questions...and more! If a user is streaming video, you can see that it is happening and who it is in real-time. With this tool, you can see which devices are communicating and which protocols they are using. If you see a sudden spike in computers communicating with a specific external host, this may mean you have malware infecting your computers. Data in hand, you can identify the infected computers and take remedial action. The NetFlow Traffic Analyzer relies on having routers on your network that send it key utilization data. The router looks at all the packets that are passing through it, and it sends the metadata about those packets (source, destination, type of packet, size of packets, etc.) to the NetFlow device. This data is then used to generate useful reports. One particularly valuable use of the NetFlow Traffic Analyzer is to monitor network traffic before and after adding bandwidth, to make sure that the additional bandwidth is having the desired result. And if you utilize network packet prioritization, also known as Quality of Service (QoS), you can see whether your QoS is positively or negatively impacting your network traffic.
