Abstract

A computer system facilitates concurrent filtering and fast-forwarding of network packets. The computer system includes a network card for interfacing with multiple computer networks, and the network adapter is able to fast-forward network packets that it receives to other network destinations without assistance from the main central processing in the computer system. A fast-forwarding cache is stored on the network card to facilitate such fast-forwarding. Network packets that are not fast-forwarded are processed by the main central processing of the computer system that may apply filtering to the network packets and route network packets accordingly. The main central processing unit provides routing information to the network card so that subsequently received network packets can be transmitted to the network destinations without intervention by the main central processing unit.
