Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0039] At present, the existing multi-controller consensus scheme will cause each controller to consume more network resources, and the consensus efficiency will also be reduced. For this reason, the present application provides a multi-controller consensus solution, which can reduce the consumption of network resources and improve consensus efficiency during the consensus process of multi-controllers in the SD-DCN network.

[0040] see figure 1 As shown, the embodiment of this app...

Abstract

The invention discloses a multi-controller consensus method applied to a block chain platform. The multi-controller consensus method comprises the steps: when a consensus request sent by a plurality of controllers in an SD-DCN network is received, selecting a target controller from the plurality of controllers; obtaining a target block sent by a target controller; and performing consensus on the target block, and transmitting the target block passing the consensus to a plurality of controllers to realize the consensus of the plurality of controllers on the target block. Multi-controller consensus in SD-DCN network is achieved by utilizing the block chain platform, and all the controllers only need to carry out data interaction with the blockchain platform, so that the problem of network resource waste caused by frequent communication between different controllers is avoided, and the performance of the controllers, the security of the consensus process and the security of SD-DCN networks are vimproved. The multi-controller consensus device, system and equipment and the readable storage medium also have the above technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a multi-controller consensus method, device, system, equipment and readable storage medium. Background technique [0002] Data Communication Network (DCN) is a distributed network computing environment and multi-level distributed data warehouse. For example, in my country, the General Office of Telecommunications of the Ministry of Posts and Telecommunications is the network center and covers all provinces, cities and autonomous regions in the country. [0003] In order to realize the university management of the DCN network, the flexible control of network traffic is generally realized through the software-defined network SDN (Software Defined Network), which constitutes SD-DCN (Software Defined-Data Communication Network). There are generally multiple controllers in the SD-DCN network, and these multiple controllers need to share data, that is, consensus among multi...
