Abstract

An approach is disclosed for monitoring performance of a network providing multicast and mobility services. A test profile is generated for determining performance of the multicast network. The test profile is uploaded on a mobile host that is configured to communicate over the multicast network, wherein the mobile host is further configured to participate in a test session according to the test profile. Test session information tracked by the mobile host is collected for evaluation of metrics for the performance of the multicast network.

Claims

1. A method comprising:

generating a test profile for determining performance on a per individual segment basis of links within a multicast network;

uploading the test profile on a mobile host that is configured to communicate over the multicast network, wherein the mobile host is further configured to participate in a test session according to the test profile;

collecting test session information tracked by the mobile host for evaluation of metrics for the performance of the individual link segments within the multicast network;

attributing a performance anomaly associated with one of the metrics to a network event; and

generating a multicast datagram for the test session, wherein an identifier is embedded in the multicast datagram or encapsulated in a header of the multicast datagram for tracking purposes.

2. A method according to claim 1, wherein the metrics relate to either joining and leaving a multicast group, channel change time, replication efficiency, packet loss, delay, or jitter.

3. A method according to claim 1, further comprising:

determining the performance anomaly based on the collected test session information; and

correlating the performance anomaly with one or more mobility and multicast events.

4. A method according to claim 1, further comprising:

monitoring the performance of the individual link segments within the multicast network based on the collected test session information; and

performing an audit of the multicast network, according to the monitoring step, to ensure satisfaction of a service level agreement.

5. A method according to claim 1, the method further comprising:

dynamically modifying the test profile during the test session.

6. A method according to claim 1, wherein the mobile host is configured to operate over a wireless access network that includes a home agent that is configured to track location of the mobile host in support of mobility services.

7. A system comprising:

a test module configured to generate a test profile for determining performance on a per individual segment basis of links within a multicast network, wherein a mobile host is configured to load the test profile for participation in a test session according to the test profile; and

a collection module configured to collect test session information tracked by the mobile host for evaluation of metrics for the performance of the individual link segments within the multicast network,

wherein a multicast datagram is generated for the test session, the multicast datagram having an embedded identifier or a header that is encapsulated for tracking purposes,

wherein a performance anomaly associated with one of the metrics is attributed to a network event.

8. A system according to claim 7, wherein the metrics relate to either joining and leaving a multicast group, channel change time, replication efficiency, packet loss, delay, or jitter.

9. A system according to claim 7, further comprising:

a performance evaluation module configured to determine the performance anomaly based on the collected test session information, and to correlate the performance anomaly with one or more mobility and multicast events.

10. A system according to claim 7, wherein the performance of the individual link segments within the multicast network is monitored and audited based on the collected test session information for ensuring satisfaction of a service level agreement.

11. A system according to claim 7, wherein the test module is further configured to dynamically modify the test profile during the test session.

12. A system according to claim 7, wherein the mobile host is configured to operate over a wireless access network that includes a home agent that is configured to track location of the mobile host in support of mobility services.

13. A method comprising:

entering an emulation mode of operation for determining performance on a per individual segment basis of links within a multicast network;

sending a test profile on a network element configured to support mobility of a mobile node, wherein the network element is further configured to output a report on the performance according to the test profile;

collecting the report to evaluate metrics for the performance of the individual link segments within the multicast network; and

attributing a performance anomaly associated with one of the metrics to a network event, based on the collected report,

wherein a multicast datagram related to the performance is generated, the multicast datagram having an embedded identifier or a header that is encapsulated for tracking purposes.

14. A method according to claim 13, wherein the metrics relate to either joining and leaving a multicast group, channel change time, replication efficiency, packet loss, delay, or jitter.

15. A method according to claim 13, further comprising:

correlating the performance anomaly with one or more mobility and multicast events.

16. A method according to claim 13, further comprising:

monitoring performance of the multicast network based on the collected report; and

performing an audit of the multicast network, according to the monitoring step, to ensure satisfaction of a service level agreement.

17. A method according to claim 13, the method further comprising:

dynamically modifying the test profile during the test session.

18. A method according to claim 13, wherein the network element is a foreign agent that is configured to communicate with a home agent in support of mobility services.
