Data switching apparatus and system

A data switching system, comprising:

• a first processor, configured to:
• determine, according to a predetermined rule, whether a switching manner of a to-be-switched data packet is electrical packet switching or optical packet switching, and generate an optical label for a second optical data packet, wherein the second optical data packet is a to-be-switched data packet determined to use optical packet switching;
• and
• a data switching apparatus, connected to the first processor, configured to:
• perform electrical packet switching on a first optical data packet received from the first processor, and perform optical packet switching on the second optical data packet received from the first processor, wherein the first optical data packet is a to-be-switched data packet determined to use electrical packet switching;
• and
• wherein the data switching apparatus comprises:
• an optical-to-electrical converter, configured to perform optical-to-electrical conversion on a first optical data packet and an optical label, wherein the first optical data packet is a to-be-switched data packet that needs to use electrical packet switching, the optical label carries switching information of a second optical data packet, and the second optical data packet is a to-be-switched data packet that needs to use optical packet switching;
• a memory coupled to a processor which is connected to the optical-to-electrical converter, wherein the processor is configured to identify whether an electrical signal output by the optical-to-electrical converter is from the optical label or the first optical data packet, according to a preset sequence same as an optical label delimiter and a preset length of the optical label;
• an electrical switch, connected to the processor, configured to switch an electrical signal that is from the first optical data packet;
• an electrical-to-optical converter, connected to the electrical switch, configured to perform electrical-to-optical conversion on an electrical signal output by the electrical switch;
• wherein the processor is further configured to generate a control signal according to an electrical signal that is from the optical label;
• and
• an optical switch, connected to the processor, configured to output the second optical data packet according to the control signal through an optical link.
