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.

  • Hi and welcome to network enigineering. You'd need to gather and add more information about how your given IPTV system actually streams data (unicast, multicast, udp, tcp?), and how the different streams can be told apart. That could be by server's IP address or alias address? by udp/tcp ports? by upper layer protocol specifics (i.e. information in the HTTP request/response) ? by multicast group addresses? – Marc 'netztier' Luethi Aug 13 at 8:09
  • When Cisco AVC is enabled, upper layer data can be exported as Netflow. When NBAR2 is enabled, Cisco equipment needs to be aware of HW resources. An authentication system (Cisco ISE or Microsoft AD, Radius) may be required to collect flows at the expected user level. If the IPTV protocol is in the App List supported by AVC, app-level information may be available without an authentication system. – Roger Sanghee Gold Aug 13 at 9:10

    sFlow or Netflow should be able to tell you that, depending on the analysis software. However, product recommendations are explicitly off-topic here. – Zac67 Aug 13 at 11:57
  • "I want to know if there is a possibility to determine how many users are streaming from specific IP addresses?" The answer is "Yes." "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." Again, the answer is "Yes." Unfortunately, product or resource recommendations are explicitly off-topic, except on Software Recommendations and Hardware Recommendations. – Ron Maupin Aug 13 at 13:00
