tl;dr: I want to know if there is a possibility to determine how many users are streaming from specific IP addresses?
I want to know if there is a software which filters NetFlow data from Cisco router (layer 4) which can help me determine that users are watching IPTV and to tell me how many users are streaming from which IP address.
Example output(format doesn't need to be like this):
#IP xx.xxx.xxx.xxx #14 connected #IP xx.xxx.xxx.xxx #32 connected
Since I'm not so familiar with networking, maybe I lack the knowledge to explain what I want, feel free to ask additional questions.
