Abstract
A network device for processing packets. The network device includes an ingress module for performing switching functions on an incoming packet. The network device also includes a memory management unit for storing packets and performing resource checks on each packet and an egress module for performing packet modification and transmitting the packet to an appropriate destination port. Each of the ingress module, memory management unit and egress module includes multiple cycles for processing instructions and each of the ingress module, memory management unit and egress module processes one packet every clock cycle.
