A network node is disclosed. The network node includes a host processor. The network node also includes an integrated circuit. The integrated circuit includes a hardware portion configured to perform a first set of TCP acceleration tasks that require a first speed level. The integrated circuit also includes a network protocol processor configured to perform a second set of TCP acceleration tasks that require a second speed level, which is lower than the first speed level. The integrated circuit further includes an embedded processor configured to perform a third set of TCP acceleration tasks that require a third speed level, which is lower than the second speed level. The network node further includes a plurality of data paths configured to couple the integrated circuit to the host processor, the plurality of data paths being implemented based on different protocols.

Systems and methods for implementing host-based security in a computer network

An architecture for implementing host-based security such that data security may be applied whenever the confidential data leaves a host computer or a networked device. The improved method and architecture may be implemented in a single integrated circuit for speed, power consumption, and space-utilization reasons. Within the integrated circuit, a combination of hardware-implemented, network processor-implemented, and software-implemented functions may be provided. The innovative host-based security architecture may offer line-rate IPSec acceleration, TCP acceleration, or both.
