Abstract
A dispatching technique dispatches packets to a plurality of service control engines (SCEs) which in aggregate may be configured to handle traffic produced by a high-speed high-capacity data link. Upstream and downstream packets that are associated with a data flow between a subscriber and a destination node in a communication network are received from by a dispatcher which is located in a path used by the data flow. For each packet, the dispatcher identifies an SCE from among a plurality of SCEs that is to receive the packet based upon an address contained in the packet. The packet is then dispatched by the dispatcher to the identified SCE which processes the packet accordingly. After processing the packet, the SCE returns the packet to the dispatcher which further processes the packet including transferring the packet onto the communication network towards its destination.
