Double-layer sheet network device and core communication automatic scheduling method

The invention discloses a double-layer sheet network device and a core communication automatic scheduling method. The device comprises a packet/circuit exchange double-layer network and a central monitoring and scheduling unit; the two layers of the network have the same topology structures, each topology node is provided with an interconnected path, and the central monitoring and scheduling unit is used for planning network links and monitoring the states of all nodes. The method based on the system includes allowing the central monitoring and scheduling unit to receive a core communication request, firstly planning packet exchange links, and detecting communication data amount; when the data amount is larger than a threshold, allowing a scheduling unit to plan circuit exchange links, if complete circuit exchange links cannot be planned, planning the packet exchange links in front of the disconnection points, and acquiring mixed links; if other circuit exchange links of nodes adjacent to the disconnection points are released, planning the circuit exchange links between two disconnection points continuously. By the aid of the method, network congestion and delay can be reduced, and the communicating efficiency can be improved.
