Heterogeneous controller cluster service active transition system and method based on abnormal perception

Abstract

The invention discloses a heterogeneous controller cluster service active scheduling system and method based on abnormal perception. The system comprises a state acquisition module, a communication agent module, an abnormal state perception module and a service active scheduling module. The method comprises the following steps: the communication agent module establishes connection with the controller and the switch; the state acquisition module acquires operating environment state parameters and load state parameters of the controller; the communication agent module obtains the flow table message issued by the controller and calculates the message credibility; the abnormal state sensing module updates abnormal parameters of the controller; the abnormal state sensing module judges whether the controller is abnormal or not; and the service active scheduling module selects the alternative controller and actively schedules the service of the abnormal controller. The method has high universality and independence, and when the controllers in the heterogeneous controller cluster are abnormal, the abnormal controllers can be timely and accurately discovered, and active scheduling can be carried out on the services of the controllers.

Description

technical field [0001] The present invention belongs to the technical field of communication, and further relates to a system and method for actively transitioning heterogeneous controller cluster services based on abnormal perception in the technical field of network communication. The present invention constructs a service active transition system for heterogeneous controller clusters in a software-defined network SDN (Software Defined Network) environment, so as to realize the abnormal perception of controller nodes and the detection of abnormalities in the heterogeneous controller cluster environment. The service of the controller node changes actively. Background technique [0002] Software Defined Networking (SDN) is a new network innovation architecture proposed by the Clean State research group of Stanford University in 2006, and it is a way to realize network virtualization. Its core technology, OpenFlow, separates the control plane of network equipment from the da...

Problems solved by technology

[0007] The purpose of the present invention is to address the shortcomings of the above-mentioned existing technologies, and propose a system and method for active transition of heterogeneous controller cluster services based on abnormality perception, which is used to solve the problems existing in the prior art between the system and heterogeneous controller clusters The coupling is too high, the exception discovery strategy of the controller reduces the business processing performance of the heterogeneous controller cluster, and the business change strategy destroys the representative security structure of the heterogeneous controller cluster and reduces the reliability of the SDN control layer.
