Abstract

A method for performance managing a service in a video and data network is provided. The method includes identifying one or more users receiving the service. Additionally, a physical network transport in the video and data network is identified for the one or more users. Further, a virtual network transport in the video and data network is identified for the one or more users. Then, performance data through the physical network transport and the virtual network transport is monitored. Once the performance data is monitored, one or more threshold values for the one or more users'"'"' service are determined and it is determined if the performance data violates at least one of the one or more threshold values.

Claims

1. A method for performance managing a service in a video and data network comprising:

identifying one or more users receiving the service;

identifying a physical network transport in the video and data network for the one or more users;

identifying a virtual network transport in the video and data network for the one or more users;

monitoring performance data through the physical network transport and the virtual network transport for the one or more users, wherein the physical network transport comprises shared physical network elements shared by a plurality of customer networks and dedicated physical network elements specific to a customer network, wherein the virtual network transport comprises shared virtual network elements shared by the plurality of customer networks and dedicated virtual network elements specific to the customer network;

determining one or more threshold values for the one or more users'"'"' service; and

determining if the performance data violates at least one of the one or more threshold values, wherein performance data for the shared physical and virtual network transport and dedicated physical and virtual network transport is analyzed to determine if the performance data violates at least one of the one or more threshold values.

2. The method of claim 1, further comprising issuing an alarm if the performance data violates at least one of the one or more threshold values.

3. The method of claim 1, wherein monitoring the performance data comprises monitoring real-time data.

4. The method of claim 1, wherein monitoring the performance data comprises monitoring nonreal-time data.

5. The method of claim 1, further comprising storing the monitored performance data.

6. The method of claim 5, further comprising creating reports using the stored performance data.

7. The method of claim 6, further comprising issuing an alarm based on the reports.

8. The method of claim 1, further comprising identifying a set of users impacted by the performance data violating the threshold values.

9. The method of claim 1, wherein determining the one or more threshold values comprises identifying a level of service for the one or more user'"'"'s service;

and

using the level of service in determining the one or more threshold values.

10. The method of claim 1, wherein the service comprises a Digital Subscriber Line (xDSL) service.

11. The method of claim 1, wherein the service comprises a Very high bit rate DSL (VDSL) service.

12. The method of claim 1, wherein the video and data network comprises a xDSL network.

13. The method of claim 1, wherein the video and data network comprises a VDSL network.

14. A method for performance managing of a service in a video and data network providing video and data services, wherein the network comprises a video cloud, data cloud, and video/data cloud, the method comprising:

identifying one or more users receiving the service;

identifying a physical network transport for the video cloud, the data cloud, and the video/data cloud for the one or more users;

identifying a logical network transport for the video cloud, the data cloud, and the video/data cloud for the one or more users;

monitoring performance data through at least one of the video cloud, the data cloud, and the video/data cloud physical and logical network transports, wherein the physical network transport comprises shared physical network elements shared by a plurality of customer networks and dedicated physical network elements specific to a customer network, wherein the virtual network transport comprises shared virtual network elements shared by the plurality of customer networks and dedicated virtual network elements specific to the customer network;

determining one or more threshold values for the one or more users'"'"' service; and

determining if the monitored performance data violates at least one of the one or more threshold values, wherein performance data for the shared physical and virtual network transport and dedicated physical and virtual network transport is analyzed to determine if the performance data violates at least one of the one or more threshold values.

15. A telecommunications device for performance managing a service in a video and data network, the telecommunications device comprising:

logic to identify one or more users receiving the service;

logic to identify a physical network transport in the video and data network for the one or more users;

logic to identify a virtual network transport in the video and data network for the one or more users;

logic to monitor performance data through the physical network transport and the virtual network transport for the one or more users, wherein the physical network transport comprises shared physical network elements shared by a plurality of customer networks and dedicated physical network elements specific to a customer network, wherein the virtual network transport comprises shared virtual network elements shared by the plurality of customer networks and dedicated virtual network elements specific to the customer network;

logic to determine one or more threshold values for the one or more users'"'"' service; and

logic to determine if the performance data violates at least one of the one or more threshold values, wherein performance data for the shared physical and virtual network transport and dedicated physical and virtual network transport is analyzed to determine if the performance data violates at least one of the one or more threshold values.

16. The telecommunications device of claim 15, further comprising logic to issue an alarm if the performance data violates at least one of the one or more threshold values.

17. The telecommunications device of claim 15, further comprising logic to identify a set of users impacted by the performance data violating the threshold values.
