Intelligence-defined optical tunnel network system and network system control method

An intelligence-defined optical tunnel network system, comprising:

• a first pod, comprising a plurality of optical add-drop sub-systems, wherein the optical add-drop sub-systems are configured to perform data transmission respectively, through a plurality of Top-of-Rack (ToR) switches with a corresponding plurality of servers, a plurality of first transmission modules of the optical add-drop sub-systems are connected to each other in ring-shaped connection to form a first transmission ring, and a plurality of second transmission modules of the optical add-drop sub-systems are connected to each other in ring-shaped connection to form a second transmission ring;
• and
• a controller, configured to set the Top-of-Rack switches correspondingly, when optical path of a first optical add-drop sub-system to a second optical add-drop sub-system on the first transmission ring is disconnected, in order to build an optical tunnel from the first optical add-drop sub-system to the second optical add-drop sub-system on the second transmission ring by the second transmission modules.
