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.

Abstract translation: 计算机系统有助于网络数据包的并发过滤和快速转发。 计算机系统包括用于与多个计算机网络接口的网卡，并且网络适配器能够将其接收的网络分组快速转发到其他网络目的地，而不需要来自计算机系统中的主要中央处理的协助。 快速转发高速缓存存储在网卡上，以方便快速转发。 不能快速转发的网络报文由计算机系统的主要中央处理进行处理，可以对网络报文进行过滤，并相应地对网络报文进行路由。 主中央处理单元向网卡提供路由信息，以便随后接收的网络分组可以被传送到网络目的地，而不需要主中央处理单元的干预。
