Abstract

The presented idea is a cheap solution for audience monitoring in multicast capable networks e.g. Ethernet, IP or UMTS. There is no need for user equipment in order to monitor the viewers'"'"' watching behavior. The measurement is done in the operator'"'"'s network; therefore, there is no need to contact the end user. The idea can be applied in systems comprising multicast capable network contention server, network devices and user equipment. The content is carried in data packets to the end user. The network devices are remote manageable. The user can choose between several contents. The aim is to measure the user statistics regarding the chosen content. According to the invention it is enough to place a measurement host with our proposed software block in the network, which collects data from the network devices in the edge of the network periodically in order to make a content access survey.

Claims

1-7. -7. (canceled)

8. A method for monitoring the use of different multicast services, said multicast services provided by at least one content server as one multicast group for each service in a multicast capable access network to which users of the multicast services are connected through network devices, wherein the network devices comprise several ports and all users are connected to different ports, comprising the steps of:

periodically retrieving directly from each network device, by a monitoring device that is not integrated in the multicast system, information identifying which multicast groups are being forwarded through which ports in the network devices;

storing the information retrieved; and

, evaluating the information to achieve a measure of the use of the different multicast services.

9. The method according to claim 8, wherein the access network is an Ethernet access network.

10. The method according to claim 8, wherein said step of periodically retrieving comprises using different paths than the multicast services use in the network for the retrieving of said information from the network devices.

11. A monitoring device connected to a multicast capable access network for monitoring the use of different multicast services which are provided by at least one content server as one multicast group for each service in the access network to which users of the multicast services are connected through network devices, wherein the network devices comprise several ports and all users are connected to different ports, and wherein it is not integrated as a part in the multicast system, comprising:

retrieving means adapted to periodically retrieve, directly from the network devices, information about which multicast groups are being forwarded through which ports in the network devices; and

,

storing means connected to the retrieving means and adapted to store the information.

12. The monitoring device according to claim 11, further comprising an evaluating means connected to said storing means, said evaluating means adapted to evaluate said information to achieve a measure of the use of the different multicast services.

13. The monitoring device according to claim 11, further comprising a timer connected to the retrieving means, said timer adapted to periodically indicate to the retrieving means that it is time to retrieve the information from the network devices.

14. The monitoring device according to claim 11, wherein it is adapted to be connected to an Ethernet access network.
