A method of aggregating a plurality of packet based communication channels is provided by the system. The communication channels connect two common endpoints, and aggregation devices are present at each point to implement an aggregation policy. The system provides a dynamic aggregation system where an aggregation policy is employed on a per packet flow basis. Packet flow can be classified by application type, so that an appropriate aggregation policy can be used for packets belonging to the flow. The selected aggregation policy is used for each flow within the aggregation devices at each endpoint.
