Hardware components of a router: – Network interfaces – Interconnection network – Processor with a memory and CPU • PC router: – interconnection network is the (PCI) bus and interface cards are NICs – All forwarding and routing is done on central processor • Commercial routers: – Interconnection network and interface cards are sophisticated – Processor is only responsible for control functions (route processor) – Almost all forwarding is done on interface cards
