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 first subscriber device of a plurality of subscriber devices connected to a first subscriber network of a plurality of subscriber networks is to be granted an exception to a packet flow priority network constraint of the first subscriber network, wherein the exception comprises prioritizing a packet flow associated with the first subscriber device over other packet flows associated with other subscriber devices of the first subscriber network;
sending, to an aggregation device that is coupled to a set of subscriber networks including the first subscriber network, first aggregation device instructions to grant the exception to packets associated with the first subscriber device that flow through the aggregation device, the first aggregation device instructions including information that identifies the first subscriber network, information for identifying the packets as being associated with the first subscriber device to distinguish packets associated with the first subscriber device from packets associated with all other subscriber devices of the first subscriber network, and a priority indicator; and
sending, to a network gateway device that serves as a network gateway for the first subscriber network to allow the plurality of subscriber devices to communicate with devices outside of the first subscriber network, first gateway device instructions to associate packets associated with the first subscriber device with the information for identifying the packets as being associated with the first 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 2 wherein the triggering event comprises an initiation of communications, by the first subscriber device, with an identified service of a plurality of different services.

5. The method of claim 4 wherein the exception further comprises prioritizing the packet flow associated with the first subscriber device over the other packet flows associated with the other subscriber devices of the first subscriber network while the first subscriber device is communicating with the identified service.

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

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

8. 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.

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

10. The method of claim 1 further comprising:
determining, by the network manager, that the first 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, second aggregation device instructions that indicate that packets associated with the first 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, second gateway device instructions to associate the packets associated with the first subscriber device with the information for identifying the packets as being associated with the first subscriber device.

11. 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.

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

13. The method of claim 1 wherein the first aggregation device instructions identify a first set of port numbers from a plurality of different port numbers that correspond to the packets associated with the first subscriber device; and
wherein the first gateway device instructions identify the first subscriber device and the first set of port numbers and comprise information that instructs the network gateway device to associate all packets originating from the first subscriber device with port numbers from the first 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 first subscriber device of a plurality of subscriber devices connected to a first subscriber network of a plurality of subscriber networks is to be granted an exception to a packet flow priority network constraint of the first subscriber network, wherein the exception comprises prioritizing a packet flow associated with the first subscriber device over other packet flows associated with other subscriber devices of the first subscriber network;
send, to an aggregation device that is coupled to a set of subscriber networks including the first subscriber network, first aggregation device instructions to grant the exception to packets associated with the first subscriber device that flow through the aggregation device, the first aggregation device instructions including information that identifies the first subscriber network, information for identifying the packets as being associated with the first subscriber device to distinguish packets associated with the first subscriber device from packets associated with all other subscriber devices of the first subscriber network, and a priority indicator; and
send, to a network gateway device that serves as a network gateway for the first subscriber network to allow the plurality of subscriber devices to communicate with devices outside of the first subscriber network, first gateway device instructions to associate packets associated with the first subscriber device with the information for identifying the packets as being associated with the first subscriber device.

15. The computing device of claim 14 wherein the processor device is furth
