ABSTRACT:
The present invention defines a system and method of routing packets using a hardware-based route cache with prefix length. When a router receives a packet, the router first searches for the routing information in the hardware-based route cache and if a match is found, the packet is forwarded to according to the routing information. The hardware-based route cache can be configured according to a search scheme employed by the router. The hardware-based route cache can be configured to provide network address length information for the destination addresses included in an incoming packet.
