1. A method for scheduling computing power power is characterized in that it includes:
the computing power nodes and access terminals send computing power information to the switch using L4 network protocol; where L4 network protocol is based on the UDP protocol and decoupled from the BGP protocol;
the switch uploads computing power information to the distributed SDN sub-controller;
distributed SDN subcontrollers collect switch status information and network quality information from switches using in-band network telemetry;
distributed SDN sub-controller uploads computing power information, switch status information and network quality information to the SDN master controller;
the SDN master controller determines the computing power scheduling policy based on computing power information, switch state information, network quality information and the master controller information of the SDN master controller;
computing power information includes resource information and request information;
the computing power node and the access terminal send computing power information to the switch directionally using L4 network protocol, including: the computing power node sends resource information to the switch using L4 network protocol;
the access terminal sends request information to the switch using L4 network protocol;
the SDN master controller determines a computing power scheduling strategy based on computing power information, switch state information, network quality information and the master controller information of the SDN master controller, including: the SDN master controller determines an alternative computing power node among the computing power nodes based on resource information and request information; the SDN master controller determines an alternative computing power node among the alternative computing power nodes based on switch state information, network quality information and the master controller information of the SDN master controller, determining an alternative optimal routing path for the access terminal to access the alternative computing power node; the SDN master controller determines a target routing path for the access terminal to access the target computing power node among the alternative optimal routing paths for the access terminal to access the alternative computing power node according to predetermined rules;
