Abstract
A gateway device for connecting a computer bus to a high-speed fiber optic ring network including an I/O host module of the computer connected to the computer bus and having at least one external communication bus for carrying both data and control blocks containing parameters relative to the composition of data frames. The gateway device also includes an adapter device physically connected to the network, and an interface which ensures transfer of the data and control blocks between the I/O host module and the adapter device. The adapter device includes a memory for storing the data frames before they are transmitted to the network and after they are received from the network, and a transfer management controller for managing the transfer of data frames between the I/O host module and the network. The controller includes a control bus which carries the control blocks and the control characters of the data frames. The adapter device further includes a high-speed bus which transports the data. The transfer interface is connected to the communication bus as well as to the high-speed bus and the control bus.
