What Is NetFlow?

Cisco Systems created NetFlow to log and record the volume of traffic passing through a network. Believe it like a fancy version of your internet history. NetFlow is the brainchild of Cisco and Enterasys, who were so excited to see what their collaboration would produce that they couldn't help but share it with the world. NetFlow is a great way to collect network traffic statistics by collecting related data from enabled routers and switches. This way, you can see how vastly your network sends and receives, where it's going, and which devices use the most bandwidth. NetFlow may also be called Cisco IOS NetFlow. NetFlow is a network protocol that provides detailed information about the traffic flowing through a network. It gives you all the statistics you need to manage and maintain your network, including how much data is being transferred. You can use NetFlow to monitor traffic patterns, which will help you identify suspicious activity and ensure your bandwidth isn't overused. You can also use it for capacity planning to know when to upgrade your network hardware. NetFlow collects information about every packet on the network and sends it back to a monitoring server. The information recorded by NetFlow is used for various network management and maintenance tasks such as traffic logging, usage statistics monitoring, and anomaly detection - all of which it accomplishes through network capacity planning and tracking and unusual traffic trends. If you want to know what websites you visited, NetFlow can tell you. If you want to know who you've been talking to on Facebook Messenger, NetFlow can say to you. If you want to know how many times you've watched that one YouTube video about cats jumping over cucumbers, NetFlow can say to you. NetFlow is the only way to truly understand what's going on in your life!
