Embodiment 1
[0032] Please refer to figure 1 , the present application discloses a software-defined network, which includes a control plane and a data plane, the control plane is mainly used to control data forwarding tasks in the network, and the data plane is used to execute data forwarding tasks in the network.
[0033] In this embodiment, the control plane of the software defined network (Software Defined Network, referred to as SDN) may include a controller 1, and the controller 1 communicates with the data plane to perform a data forwarding task for any data stream on the data plane. Implement controls. The data plane of the software-defined network can be constructed through some switches, that is, the data plane includes multiple switches (such as switches A, B, C, D, E, F, G) with topological connections, and each switch is connected to the control plane The controller 1 in the data plane is connected by communication, and each switch in the data plane receives the configuration ...
Embodiment 2
[0055] Please refer to Figure 5 , on the basis of the software-defined network disclosed in the first implementation, this embodiment discloses a network control method for a software-defined network, which mainly includes steps S110-S140, which will be described separately below.
[0056] It should be noted that the software-defined network in this embodiment includes a control plane and a data plane. Among them, the control plane is used to control the data forwarding tasks in the network, and the controller 1 in it includes an initialization module 11, a topology management module 12, a routing decision module 13, a sampling control module 14, a path allocation module 15, and a verification module 16 And error localization module 17, can refer to for the specific structure of controller 1 figure 2 . Among them, the data plane is used to perform data forwarding tasks in the network, and any switch 2 in it includes a configuration information acquisition module 21, a dyna...
