Abstract
One aspect of the invention relates to a network interface system for interfacing a host system with a network. The network interface system includes a bus interface system, a media access control system, and a security system. The security system selectively perform security processing on data incoming from the network based on security associations stored in a memory external to the network interface system, typically a host system memory. The security association for any given frame, when available, is fetched from the external memory after the frame begins to arrive in the network interface system based in part on information contained in the frame. Preferably, the fetch begins before the frame is fully received and the security association is queued whereby security processing can begin without having to wait for the security association to be fetched.
