External network network interface device without interim storage connected to high-speed serial bus with low latency and high transmission rate

摘要

A network interface for coupling a computer node to a network has a physical interface which is coupleable to the network for coupling the network interface to the network. The network interface is coupleable to the computer node through a high-speed serial bus which has a latency and a signal transmission rate sufficient to enable transmission of signals between the network and the computer node without interim storage of the signals in a buffer on the network interface. In a preferred embodiment, the computer node has a processor capable of processing network protocols and the signals may be transmitted between the network and the computer node without processing of the network protocols by a processor on the network interface.
