An intelligence-defind optical tunnel network system includes a first tier network and a second tier network. The first tier network includes multiple pods, any one of which includes multiple Optical Add-Drop Sub-systems (OADS) configured to transmit data between corresponding servers through ToR switches. The second tier network includes multiple Optical Switch Interconnect Sub-systems (OSIS). Any two of the OSISs transmit a corresponding lateral optical signal via a first line correspondingly. Any two adjacent OSISs are coupled to the OADSs in the same pod of the first tier via multiple optical paths respectively.

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

An network system control method includes: planning an optical tunnel network according to a routing path table and transmitting a control command according to an optical tunnel network configuration of the optical tunnel network by a tunnel scheduling module, wherein the optical tunnel network includes multiple optical tunnels, and each of the optical tunnels includes a routing path and a wavelength; outputting a control signal to multiple optical switches and multiple top-of-rack switches according to the control command by a configuration managing module; receiving flow statistics of the dataflows of the optical tunnels from the top-of-rack switches, calculating dataflow rates of the dataflows and bandwidth usage rates of the optical tunnels, and transmitting a load notification when one of the bandwidth usage rates exceeds an preset interval by a bandwidth usage monitor; and replanning the optical tunnel network according to the load notification by the tunnel scheduling module.

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

An intelligence-defined optical tunnel network system includes multiple Optical Switch Interconnect Sub-systems (OSIS). Any one of the OSIS includes a receiving sub-module, an output sub-module, an interconnection fabric module and an optical switching sub-module. The receiving module is configured to receive multiple first and third upstream optical signals from first and second Optical Add-Drop Sub-systems (OADS) corresponding to the first and the second pods. The output sub-module is configured to output multiple second and fourth downstream optical signals to the first and second OADS. The interconnect circuit sub-module is configured to connect adjacent two of the OSISs and any two of the OSISs transmit a corresponding lateral transmission optical signal via a first line correspondingly. The optical switching sub-module is configured to transmit optical signals between the receiving sub-module, the output sub-module, and the interconnection fabric module.
