Abstract

An architecture is provided that can scale content resolution in order to mitigate errors in a provisioned service of a communication network, such as a wireless service or a femtocell service that integrates with DSL or other broadband carriers. The architecture can identify fault conditions relating to e.g., bandwidth oversubscription or symbolization integrity. Based upon such identification, the architecture can alter encoding format codecs of certain types of content in order to reduce their resolution/quality, thereby mitigating bandwidth oversubscription fault conditions or freeing up space (without necessarily increasing bandwidth) to insert additional FEC code.

First claim

What is claimed is:

1. A gateway device, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining traffic data indicative of a state of network traffic that is communicated via the gateway device of a network comprising network devices, wherein the network traffic comprises first content encoded according to a first encoding format and second content encoded according to a second encoding format;
based on the traffic data, determining an update to the state of the network traffic; and
based on priority data indicative of a first priority of the first encoding format and a second priority of the second encoding format, determining, from between the first encoding format and the second encoding format, a selected encoding format to modify to effectuate the update.

2. The gateway device of claim 1 , wherein the determining the traffic data comprises determining the network traffic is in a congested state.

3. The gateway device of claim 2 , wherein the determining the network traffic is in the congested state comprises determining:
a bandwidth measure of the network traffic exceeds a defined bandwidth threshold, or
a bit error rate measure of the network traffic exceeds a defined error rate threshold.

4. The gateway device of claim 2 , wherein the determining the update to the state of the network traffic comprises determining that a first bit rate of a portion the network traffic with the selected encoding format is to be reduced to a second bit rate that is less than the first bit rate.

5. The gateway device of claim 4 , wherein the operations further comprise updating the state of the network traffic in response to reducing the first bit rate of the portion of the network traffic with the selected encoding format to the second bit rate.

6. The gateway device of claim 1 , wherein the determining the traffic data comprises determining the network traffic is in a spare capacity state.

7. The gateway device of claim 6 , wherein the determining the network traffic is in the spare capacity state comprises determining:
a bandwidth measure of the network traffic is below a defined bandwidth threshold, or
a bit error rate measure of the network traffic is below a defined error rate threshold.

8. The gateway device of claim 6 , wherein the determining the update to the state of the network traffic comprises determining that a first bit rate of a portion the network traffic with the selected encoding format is to be increased to a second bit rate that is greater than the first bit rate.

9. The gateway device of claim 8 , wherein the operations further comprise updating the state of the network traffic in response to increasing the first bit rate of the portion of the network traffic with the selected encoding format to the second bit rate.

10. The gateway device of claim 1 , wherein the operations further comprise receiving remote traffic data indicative of a remote state of remote network traffic that is communicated via a remote gateway device of the network.

11. The gateway device of claim 10 , wherein the determining the update to the state of the network comprises determining the update based on the remote traffic data.

12. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising, comprising:
determining traffic data indicative of a state of network traffic that is communicated via a gateway device of network devices of a network, wherein the network traffic comprises first content encoded according to a first encoding format and second content encoded according to a second encoding format;
determining an update to the state of the network traffic based on the traffic data; and
based on priority data indicative of a first priority of the first encoding format and a second priority of the second encoding format, determining, from between the first encoding format and the second encoding format, a selected encoding format to modify to effectuate the update.

13. The machine-readable storage medium of claim 12 , wherein the determining the update to the state of the network traffic comprises determining that a first bit rate of a portion the network traffic with the selected encoding format is to be modified to a second bit rate that is different from the first bit rate.

14. The machine-readable storage medium of claim 13 , wherein the operations further comprise updating the state of the network traffic in response to modifying the first bit rate of the portion of the network traffic with the selected encoding format to the second bit rate.

15. The machine-readable storage medium of claim 12 , wherein the operations further comprise receiving different traffic data indicative of a different state of different network traffic that is communicated via a different gateway device of the network.

16. The machine-readable storage medium of claim 15 , wherein the determining the update to the state of the network comprises determining the update based on the different traffic data.

17. A method, comprising:
determining, by a device comprising a processor, traffic data indicative of a state of network traffic that is communicated via the gateway device of a network comprising network devices, wherein the network traffic comprises first content encoded according to a first encoding format and second content encoded according to a second encoding format;
determining, by the device, an update to the state of the network traffic based on the traffic data; and
based on priority data indicative of a first priority of the first encoding format and a second priority of the second encoding format, determining, by the device and from between the first encoding format and the second encoding format, a selected encoding format to modify to effectuate the update.

18. The method of claim 17 , wherein the determining the update to the state of the network traffic comprises determining that a first bit rate of a portion the network traffic with the selected encoding format is to be reduced to a second bit rate that is lower than the first bit rate.

19. The method of claim 17 , wherein the determining the update to the state of the network traffic comprises determining that a first bit rate of a portion the network traffic with the selected encoding format is to be increased to a second bit rate that is higher than the first bit rate.

20. The method of claim 17 , wherein the determining the update to the state of the network traffic comprises determining the update based on different traffic data indicative of a different state of different network traffic that is communicated via a different gateway device of the network.
