Abstract
Methods and systems for individual forward-link and return-link policies for network communication are disclosed. In some aspects, the individual forward-link and return-link policies define how data is routed over a plurality of access networks between a client-side enforcement unit and a provider-side enforcement unit. In some aspects, the individual policies may be based on metrics collected by the client-side and provider-side enforcement units, which may be positioned on each end of one or more access networks.
Claims20
A system for dynamic policy updates for an enforcement unit, comprising:
- a plurality of client-side enforcement units, a client-side enforcement unit of the plurality of client-side enforcement units comprising:
- one or more first network interfaces for communication over a first access network and a second access network, the first access network having a first characteristic between the client-side enforcement unit and a destination network, the second access network having a second characteristic between the client-side enforcement unit and the destination network, the second characteristic different than the first characteristic;
- and
- a first processing unit to:
- dynamically enforce an individual return-link policy based on received policy information specific to the client-side enforcement unit;
- receive a network message from a network device for delivery to the destination network;
- transmit, via the one or more first network interfaces, the network message over at least one of the first access network and the second access network using the individual return-link policy;
- and
- a policy management unit, comprising:
- one or more second network interfaces for communication over at least one of the first access network and the second access network;
- and
- a second processing unit to:
- obtain information indicating respective transmissions by each client-side enforcement unit of the plurality of client-side enforcement units over the first access network and over the second access network,
- update the policy information specific to each client-side enforcement unit of the plurality of client-side enforcement units based on the information, and
- transmit, via the one or more second network interfaces, the updated policy information specific to each client-side enforcement unit.

A method of dynamically updating routing policy for a remote network routing device, the method comprising:
- managing, by a client-side enforcement unit, an individual return-link policy based on received policy information specific to the client-side enforcement unit, the individual return-link policy for transmission of network messages over a first access network having a first characteristic and a second access network having a second characteristic different than the first characteristic;
- receiving, by the client-side enforcement unit, a first network message from a network device for delivery to a destination network accessible via the first access network and the second access network;
- transmitting, by the client-side enforcement unit, the first network message over at least one of the first access network and the second access network using the individual return-link policy;
- receive, by the client-side enforcement unit, updated policy information specific to the client-side enforcement unit, the updated policy information based on transmissions by the client-side enforcement unit over the first access network and the second access network;
- update, by the client-side enforcement unit, the individual return-link policy based on the received updated policy information;
- receive, by the client-side enforcement unit, a second network message from the network device for delivery to the destination network;
- and
- transmit, by the client-side enforcement unit, the second network message over the first access network or the second access network using the updated individual return-link policy.
