NetFlow turns out to be a proprietary open protocol created by Cisco to closely watch network traffic. Netflow analyzes sessions of the network traffic, recording each TCP/IP transaction.
We have implemented the analyzer in our network. If you have more than 10k flows per second, it will create issues for our customers. As a result, we’ll have to cancel your service. However, if your activity is 100% legal, you will not face such a problem. Feel free to contact us to timely resolve such issues.
