The invention provides an SDN (Software Defined Network) dynamic control method and device. Relates to the technical field of wireless communication. The method comprises the following steps: collecting network link information and network node information of an SDN network in real time; inputting the collected information into a trained retransmission prediction model to obtain first retransmission information of each node in the SDN network, and determining a target tracking node; calculating feature importance information of the target tracking node based on the trained retransmission prediction model; key features of the corresponding target tracking nodes are determined; and generating corresponding control information based on the key features, and issuing the control information to the corresponding target tracking node so as to adjust the configuration information of the target tracking node. According to the invention, the problem of network delay caused by high packet loss retransmission rate of the wireless SDN network in the prior art can be solved.
Description
technical field [0001] The present disclosure relates to the technical field of wireless networks, and in particular, to an SDN network dynamic control method, an SDN network dynamic control device, a computer-readable storage medium, and electronic equipment. Background technique [0002] As a software-based network architecture technology, Software Defined Networking (SDN) supports centralized network status control and realizes the transparency of underlying network facilities to upper-layer applications. At the same time, it has flexible software programming capabilities, which improves the automatic management and control capabilities of the network, and can solve the problems faced by current network systems such as limited resource expansion, poor networking flexibility, and difficulty in quickly meeting business needs. [0003] For a wireless SDN network, due to the shared characteristics of the medium, multiple network nodes may transmit on the same channel at the s...
