Method and apparatus for searching a network connection

Method and apparatus for implementing use of a network connection table. In one aspect, searching for network connections includes receiving a packet, and zeroing particular fields of connection information from the packet if a new connection is to be established. The connection information is converted to an address for a location in a direct table using a table access process. The direct table stores patterns and reference information for new and existing connections. The connection information is compared with at least one pattern stored in the direct table at the address to find reference information for the received packet.
