Abstract

A method of managing a plurality of subscribers using a communication network involving: obtaining network usage data for a plurality of service flows associated with the plurality of subscribers using the network; from the network usage data, determining which of the plurality of subscribers has been using an excess amount of bandwidth; determining that at least some part of the network is currently in a congested state; and in response to determining that at least some part of the network is currently in the congested state, sending a policy decision to a gateway device that controls bandwidth resources currently being provided to the identified subscriber, said policy decision instructing the gateway device to reduce network bandwidth that is currently being provided to support existing service flows for the identified subscriber.

Claims

1. A method of managing a plurality of subscribers using a communication network, said method comprising:

obtaining network usage data for a plurality of service flows associated with the plurality of subscribers using the network;

from the network usage data, determining which of the plurality of subscribers has been using an excess amount of bandwidth;

determining that at least some part of the network is currently in a congested state; and

in response to determining that at least some part of the network is currently in the congested state, sending a policy decision to a gateway device that controls bandwidth resources currently being provided to the identified subscriber, said policy decision instructing the gateway device to reduce network bandwidth that is currently being provided to support existing service flows for the identified subscriber.

2. The method of claim 1, wherein determining that at least some part of the network is in a congested state involves receiving a notification from another entity on the network that said at least some part of the network is in the congested state.

3. The method of claim 1, wherein determining that at least some part of the network is in a congested state involves analyzing the network usage data for the plurality of service flows.

4. The method of claim 1, wherein determining that at least some part of the network is in a congested state involves determining that current time falls within a predefined period of time.

5. The method of claim 1, wherein network is a cable network including a plurality of cable modem termination systems (CMTSs) and wherein sending the policy decision to the gateway device involves sending the policy decision to one of the plurality of CMTSs.

6. The method of claim 1, wherein network is a mobile network.

7. The method of claim 1, wherein said policy decision instructing the gateway device to reduce network bandwidth that is being provided to the identified subscriber instructs the gateway device to reduce only the network bandwidth that is being provided to specified applications being currently used by the identified subscriber.

8. The method of claim 1, wherein determining which of the plurality of subscribers is using an excess amount of bandwidth for said at least some part of the network involves examining usage by that subscriber over an extended period of time.

9. The method of claim 1, wherein determining which of the plurality of subscribers is using an excess amount of bandwidth for said at least some part of the network involves referencing a database which identifies subscribers which have been using excess bandwidth.

10. A system for managing a communication network having a plurality of devices through which a plurality of subscribers connect to the network, one or more monitoring devices for measuring network usage data for the plurality of subscribers, and a gateway device for controlling network bandwidth resources that are made available to each of the subscribers, said system comprising:

a policy server that instructs the control device regarding what bandwidth is made available to each of the plurality of subscribers;

an analysis module configured to;

(1) obtain usage data for a plurality of service flows associated with the plurality of subscribers using the network;

(2) from the network usage data, determine which of the plurality of subscribers has been using an excess amount of bandwidth;

(3) determine that at least some part of the network is currently in a congested state; and

(4) notify the policy server of the congested state,

wherein the policy sever is programmed to respond to the notification from the analysis module by instructing the gateway device to reduce network bandwidth that is currently being provided to support existing service flows for the identified subscriber.

11. The system of claim 10, wherein the analysis module is configured to determine that at least some part of the network is in a congested state by receiving a notification from another entity on the network that said at least some part of the network is in the congested state.

12. The system of claim 10, wherein the analysis module is configured to determine that at least some part of the network is in a congested state by analyzing the network usage data for the plurality of service flows.

13. The system of claim 10, wherein the analysis module is configured to determine that at least some part of the network is in a congested state by determining that current time falls within a predefined period of time.

14. The system of claim 10, wherein network is a cable network including a plurality of cable modem termination systems (CMTSs) and wherein the gateway device is one of the plurality of CMTSs.

15. The system of claim 10, wherein network is a mobile network.

16. The system of claim 10, wherein said policy decision instructing the gateway device to reduce network bandwidth that is being provided to the identified subscriber instructs the gateway device to reduce only the network bandwidth that is being provided to specified applications being currently used by the identified subscriber.

17. The system of claim 10, wherein determining which of the plurality of subscribers is using an excess amount of bandwidth for said at least some part of the network involves examining usage by that subscriber over an extended period of time.

18. The system of claim 10, wherein determining which of the plurality of subscribers is using an excess amount of bandwidth for said at least some part of the network involves referencing a database which identifies subscribers which have been using excess bandwidth.
