Methods and systems for dynamic policy based traffic steering over multiple access networks

A method of dynamically updating routing policy, 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;
• receiving, 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;
• updating, by the client-side enforcement unit, the individual return-link policy based on the received updated policy information;
• receiving, by the client-side enforcement unit, a second network message from the network device for delivery to the destination network;
• and
• transmitting, 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.
