Abstract
A method of mediating the flow of datagrams to a destination in a network is disclosed. The method includes the steps of receiving a datagram at a port of a network device, evaluating a destination address for the datagram based on fields in the incoming packet, searching a longest prefix match (LPM) table using the destination address as a LPM key, determining an address table index and an offset based on entries found in the search of the longest prefix match table, searching an address table using the address table index and the offset as an address key to determine an egress port number of the network device and forwarding the packet based upon at least the egress port number.
