Abstract
A network system in which a plurality of computers and a terminal device are connected to one another through a node by telecommunication lines, and one computer is designated by the terminal device to communicate data with the terminal device through the node, the node detects a stop or fault of the one computer, or a stop or fault of the telecommunication line connecting the one computer and the node to each other, in response to an incoming call for the one computer from the terminal device, and informs the terminal device of the stop or fault, in response to the detection of the stop or fault. The terminal device changes an address of the designated computer to perform the communication from an address of the one computer to an address of another computer, in response to the information of the stop or fault, whereby the terminal device issues a call to the another computer on the basis of the new address through the node, in the case where the one computer is designated as a computer to perform the communication, after the change of the address.
