Abstract
A network processor for performing residential gateway processing tasks. The network processor includes a first cluster of packet processors and a second cluster of packet processors, wherein each of the first cluster and the second cluster includes a main packet processor and a secondary packet processor, wherein the main packet processor performs at least routing of incoming packets and the secondary packet processor performs off-loading tasks for the main packet processor; a plurality of Ethernet media access control (MAC) adapters for interfacing with a plurality of subscriber devices connected to a residential gateway; an external-network MAC adapter for interfacing with a wide area network (WAN) connected to the network processor; and an ingress handler for at least load balancing the processing of packets between the first cluster and the second cluster.
