TWO PARALLEL ENGINES FOR HIGH SPEED TRANSMIT IPSEC PROCESSING

摘要

The invention relates to a network interface system (2) for interfacing a host system (6) with a network (8). The network interface system (2) includes a bus interface system (6), a media access control system (10), and a security system (14). The network interface (2) offloads IPsec processing from the host system (6). According to the invention, the security system (14) includes two processors (20, 2l.) for encrypting the outgoing data. Outgoing data packets are sent alternately to one or the other processor (20, 21), whereby transmission processing can be accelerated relative to receive processing.
