Abstract

A scheme for dynamically connecting I/O devices through a network is disclosed. It enables separating I/O devices from a host system unit and connecting them to the host system unit through a network. In one preferred embodiment, provided in the host side is a converter that encapsulates an I/O command into one or more data link frames so that the frames containing the I/O command are sent through the network. Also provided in the device side is a counter-converter that retrieves the I/O command from the data link frames received through LAN. The network may be either a wired or wireless network.
