Abstract

An interconnecting apparatus includes one or more interfaces. Each interface connects to a network. The interconnecting apparatus interconnects the networks attached to the interfaces. The device utilizes distributed autonomous forwarding engines on each interface in that each interface has a forwarding engine corresponding to it. Each forwarding engine only knows the configuration information and how to receive and transmit packets on the one interface to which it corresponds. Each forwarding engine acts independently to process packets, yet each interacts together to collectively provide packet forwarding which is protocol independent, interface independent, and scalable.
