Abstract

Implementing network constraint exceptions on a per device basis is disclosed. A network manager determines that a subscriber device associated with a subscriber network is to be granted an exception to a network constraint of the subscriber network. An aggregation device that is coupled to a set of subscriber networks including the subscriber network is sent aggregation device instructions to grant the exception to packets associated with the subscriber device that flow through the aggregation device. A network gateway device that serves as a network gateway for the subscriber network is sent gateway device instructions to associate packets associated with the subscriber device with information for identifying the packets as being associated with the subscriber device.

First claim

What is claimed is:

1. A method comprising:
determining, by a network manager executing on a computing device, that a subscriber device associated with a first subscriber network of a plurality of subscriber networks is to be granted an exception to a network constraint of the first subscriber network;
sending, to an aggregation device that is coupled to a set of subscriber networks including the first subscriber network, aggregation device instructions to grant the exception to packets associated with the subscriber device that flow through the aggregation device, the aggregation device instructions including information that identifies the first subscriber network, information for identifying packets as being associated with the subscriber device, and a maximum bandwidth to be accorded the subscriber device; and
sending, to a network gateway device that serves as a network gateway for the first subscriber network, gateway device instructions to associate packets associated with the subscriber device with information for identifying the packets as being associated with the subscriber device.

2. The method of claim 1 wherein the exception is to be granted upon a triggering event detected at a future point in time.

3. The method of claim 2 wherein the triggering event comprises a specified date and time.

4. The method of claim 3 wherein the network constraint comprises a predetermined bandwidth constraint associated with the first subscriber network, and wherein the exception comprises providing the subscriber device a bandwidth greater than the predetermined bandwidth constraint associated with the first subscriber network for a predetermined timeframe.

5. The method of claim 2 wherein the triggering event comprises an initiation of communications, by the subscriber device, with an identified service of a plurality of different services.

6. The method of claim 5 wherein the network constraint comprises a predetermined bandwidth constraint associated with the first subscriber network, and wherein the exception comprises providing the subscriber device a bandwidth greater than the predetermined bandwidth constraint associated with the first subscriber network while the subscriber device is communicating with the identified service.

7. The method of claim 1 wherein the information for identifying the packets as being associated with the subscriber device comprises a set of port numbers.

8. The method of claim 1 wherein the information for identifying the packets as being associated with the subscriber device comprises a packet flow identifier that identifies a packet flow associated with the subscriber device.

9. The method of claim 1 wherein the aggregation device comprises one of a cable modem termination system, a digital subscriber line access multiplexer, and a fiber aggregation node.

10. The method of claim 1 wherein the gateway device instructions identify the subscriber device and a set of port numbers.

11. The method of claim 1 further comprising:
determining, by the network manager, that the subscriber device has connected to a second subscriber network of the plurality of subscriber networks;
sending, to an aggregation device that is coupled to the second subscriber network, aggregation device instructions that indicate that packets associated with the subscriber device that flow through the aggregation device that is coupled to the second subscriber network be granted the exception; and
sending, to a network gateway device that serves as a network gateway for the second subscriber network, gateway device instructions to associate the packets associated with the subscriber device with the information for identifying the packets as being associated with the subscriber device.

12. The method of claim 1 wherein the exception is granted upon a triggering event and for a period of time until a terminating event occurs, and further comprising:
determining that the terminating event has occurred; and
in response to determining that the terminating event has occurred:
sending, to the aggregation device, instructions that revoke the exception; and
sending, to the network gateway device, instructions that revoke the exception.

13. The method of claim 1 wherein the aggregation device instructions identify a first set of port numbers from a plurality of different port numbers that correspond to packets associated with the subscriber device, and a second set of port numbers that correspond to packets associated with every other device connected to the first subscriber network other than the subscriber device; and
wherein the gateway device instructions identify the subscriber device, the first set of port numbers, and the second set of port numbers, and information that instructs the network gateway device to associate all packets originating from the subscriber device with port numbers from the first set of port numbers, and to associate all packets originating from every other device connected to the first subscriber network other than the subscriber device with port numbers from the second set of port numbers.

14. A computing device, comprising:
a memory; and
a processor device coupled to the memory, the processor device configured to:
determine that a subscriber device associated with a first subscriber network of a plurality of subscriber networks is to be granted an exception to a network constraint of the first subscriber network;
send, to an aggregation device that is coupled to a set of subscriber networks including the first subscriber network, aggregation device instructions to grant the exception to packets associated with the subscriber device that flow through the aggregation device, the aggregation device instructions including information that identifies the first subscriber network, information for identifying packets as being associated with the subscriber device, and a maximum bandwidth to be accorded the subscriber device; and
send, to a network gateway device that serves as a network gateway for the first subscriber network, gateway device instructions to associate packets associated with the subscriber device with information for identifying the packets as being associated with the subscriber device.

15. A non-transitory computer-readable storage medium that includes instructions configured to cause a processor device to:
determine that a subscriber device associated with a first subscriber network of a plurality of subscriber networks is to be granted an exception to a network constraint of the first subscriber network;
send, to an aggregation device that is coupled to a set of subscriber networks including the first subscriber network, aggregation device instructions to grant the exception to packets associated with the subscriber device that flow through the aggregation device, the aggregation device instructions including information that identifies the first subscriber network, information for identifying packets as being associated with the subscriber device, and a maximum bandwidth to be accorded the subscriber device; and
send, to a network gateway device that serves as a network gateway for the first subscriber network, gateway device instructions to associate packets associated with the subscriber device with information for identifying the packets as being associated with the subscriber device.

16. The method of claim 1 wherein the aggregation device instructions identify a first set of port numbers from a plurality of different port numbers that correspond to packets associated with the subscriber device and
wherein the gateway device instr
