Data Transmission System Used Between Multiple Servers, Data Interface Device, and Data Transmission Method

A data interface device comprising:

• a data stream receiving module configured to receive a data stream of a server connected to the data stream receiving module;
• a data identification module configured to generate corresponding stream identification information according to the data stream;
• a forwarding scheduling module configured to generate a forwarding request according to the stream identification information, wherein the forwarding request comprises a destination address of the data stream;
• a control signal receiving and sending module configured to send the forwarding request to the controller device and receive a confirmation signal of the forwarding request;
• and
• a data receiving and sending module configured to convert the data stream into an optical signal according to the confirmation signal of the forwarding request and send the optical signal to the all-optical switching matrix.

A data transmission method comprising:

• receiving a data stream of a server;
• generating corresponding stream identification information according to the data stream;
• generating a forwarding request according to the stream identification information, wherein the forwarding request comprises a destination address of the data stream;
• sending the forwarding request to a controller device such that the controller device generates control logic;
• receiving a confirmation signal of the forwarding request that is fed back after the controller device generates the control logic;
• converting the data stream into an optical signal according to the confirmation signal of the forwarding request;
• and
• sending the optical signal to an all-optical switching matrix such that the all-optical switching matrix forwards the data stream according to the control logic.
