APPARATUS AND METHODS FOR EFFICIENT NETWORK ADDRESS TRANSLATION AND APPLICATION LEVEL GATEWAY PROCESSING

摘要

Apparatus and methods for efficient NAT and ALG processing is disclosed. An exemplary method includes the operations of deep scanning a packet received over a connection to determine an application level gateway (ALG) process to be performed on the packet associating the connection with the ALG process and forwarding additional packets received over the connection to receive the ALG process based on said associating so that deep scanning of the additional packets is bypassed. An exemplary apparatus includes a processor to deep scan a packet received over a connection to determine an ALG process to be performed on the packet a database to associate the connection with the ALG process and a packet transmitter to forward additional packets received over the connection to receive the ALG process based on said associating so that deep scanning of the additional packets is bypassed.
