Example Embodiment
[0037] The technical solutions in the embodiments of the present invention will be described in detail below in connection with the drawings of the embodiments of the present invention. The described embodiments are merely a part of the embodiments of the invention.
[0038] The present invention solves the technical solution of the above technical problems:
[0039] like figure 1 The present invention is shown as a multi-path-dependent controller deployment model diagram of the present invention, and different types of lines represent different control links of different controllers. figure 1 The SDN switches are jointly controlled by one or more controllers. As long as the SDN switch does not lose contact with all the controllers connected, the control plane can be guaranteed, and the deployment position of the control center is in communication with each controller. Delay the minimum controller position determination. In the deployment scheme, the user accepts the maximum fault...
