Abstract

A novel network architecture that integrates the functions of an internet protocol (IP) router into a network processing unit (NPU) that resides in a host computer'"'"'s chipset such that the host computer'"'"'s resources are perceived as separate network appliances. The NPU appears logically separate from the host computer even though, in one embodiment, it is sharing the same chip.

a central processing unit (CPU) executing an operating system; and

a chipset including a network processing unit (NPU) that is in communication with the CPU and at least first and second auxiliary processing units,

wherein the first and second auxiliary processing units can communicate application data directly to each other through the NPU using standard networking protocols, including Internet Protocol (IP), Transmission Control Protocol (TCP), and User Datagram Protocol (UDP), without involvement from the CPU and without involvement from the operating system,

wherein the NPU perceives the first and the second auxiliary processing units as separate network appliances that provide both local access and remote access in a distributed computing environment, and

wherein the NPU is logically separate from the operating system and the CPU.

2. The computing device according to claim 1, further comprising a virtual port that communicates between the CPU and the NPU, wherein the virtual port communicates with the NPU as if the NPU is an external network appliance, using standard networking protocols.
