Patent abstract
Described are an apparatus and method of forwarding Internet Protocol (IP) packets. At least one fixed-length key having a predetermined number of bits is produced in response to an IP address in an IP packet. At least a portion of the fixed-length key is hashed to obtain a hash value. The fixed-length key is compared with a key value stored in each data-item in a hash bucket associated with the hash value to find the data item that has the key value that matches the fixed-sized key and to obtain from that data item routing information that is used to forward the IP packet.
