Abstract
In a router coupled to a number of networks, a data packet is received from a first one of the networks and routed to a second one of the networks. The data packet includes a first portion having a destination network address. The destination network address for the data packet is input to a content addressable memory ("CAM") while the router is still receiving at least a portion of the data packet, so that the CAM, having network address information stored therein, identifies one of the networks coupled to the router and corresponding to the destination address of the data packet while the router is still receiving at least a portion of the data packet.
