Abstract

A client-server arrangement permits recruitment and control of client peripherals to be effected from the server side is described. A client server system has a server device, a client device, and a peripheral device. The client device is in communication with the server device. The peripheral device is in communication with the client device. The client device has a port server to convert data between an IP format and a non-IP format. The peripheral device exchanges data with the port server in the non-IP format. The server device includes a computational device to exchange data with the port server in the IP format.

transmitting non-IP data from the first peripheral device to a first port server comprised by the first client device in a first non-IP format, wherein the first non-IP format is a first bus protocol;

converting the non-IP data into a first set of IP data in an IP format with the first port server, wherein the first set of IP data comprises a first IP address linked to the first client device and a first port number linked to the first peripheral device;

transmitting non-IP data from the second peripheral device to the second port server comprised by the second client device in a second non-IP format, wherein the second non-IP format is a second bus protocol;

converting the non-IP data into a second set of IP data in an IP format with the second port server, wherein the second set of IP data comprises a second IP address linked to the second client device and a second port number linked to the second peripheral device;

transmitting the first set of IP data from the first port server to the server device with a first operation request;

transmitting the second set of IP data from the second port server to the server device with a second operation request; and

executing a first operation with the server device in accordance with the first operation request and executing a second operation with the server device in accordance with the second operation request, wherein the server device executes the first operation request and the second operation request with server-side software as though the first peripheral device and second peripheral device are architecturally components of the server device.
