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

An intelligence-defined optical tunnel network system, comprising:

• a first tier network, comprising a plurality of pods, wherein any one of the pods comprises a plurality of optical add-drop sub-systems, the optical add-drop sub-systems perform data transmission, through a plurality of top-of-rack switches, with a corresponding plurality of servers;
• and
• a second tier network, comprising a plurality of optical switch interconnect sub-systems, wherein any two of the optical switch interconnect sub-systems transmit a corresponding lateral transmission optical signal between each other through a corresponding first line,
• wherein any two adjacent optical switch interconnect sub-systems of the optical switch interconnect sub-systems are coupled to the optical add-drop sub-systems of the same pod in the first tier network through a plurality of optical paths.
