Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] The present invention considers that the controllers in the architecture of the plane are all at the same level, such as figure 1 As shown, the control plane is mainly composed of four controllers 1 to 4, and each controller governs its own area. Assume that the data has been unified before, all of which are V values, but the network has changed in the area of ​​controller 1, and a new value is generated called V+V'. In order to make each controller of the control plane grasp the global information, the controller 1 Send the new value V+V' to the remaining three controllers. At the same time, the network in the area of ​​controller 4 also changes, generating a new value V+V" and sending the new value to the other three controllers. At this time, it is easy to cause data confusion, a large number of control plane signaling, etc. The pr...

Abstract

The invention provides a consistency construction method for a plane control architecture based on SDN (Software Defined Networking), particularly for the consistency problems of a network topology view among multiple collaborative controllers and the like in the SDN, discloses a consistency problem solution. The solution adopts a method that: one authority controller is selected from multiple plane controllers to carry out global control so as to ensure consistency of required information; and meanwhile, a preemptive access right mechanism is adopted among the controllers to carry out application for a data modification permission..

Description

technical field [0001] The invention belongs to the technical field of software-defined network, especially for the consistency problem of controller network topology view under the planar architecture of multi-controller cooperation in software-defined network, and proposes a planar control architecture based on software-defined network Consistency build method. Background technique [0002] With the rise of the data era of cloud computing, Internet of Things, big data and other applications, the development of traditional networks is difficult to cope with flexible data resource requests. Corresponding network architecture update schemes have emerged one after another. The research on the programmable network proposed first provides a theoretical basis for the development of Software Defined Networking (SDN); the active network allows users to write simple programs, but the security is facing The 4D architecture separates the decision-making plane from the data plane to c...
