Abstract

The invention provides a blockchain-based multi-controller synchronization method and device in a software defined network, and the method comprises the steps: transmitting consensus acknowledgement information to a target controller of an acquired access blockchain system so that the target controller transmits a first block including the local information of the target controller to a blockchainsystem according to the consensus acknowledgement information; transmitting a second block including the local information to each controller, so that each controller updates its stored network viewaccording to the local information, thereby achieving the synchronization of the information of multiple controllers. The method and device provided by the invention realize information synchronization between multiple controllers through a license chain, reduce unnecessary information interaction, and improve the efficiency of the controller, and improve the safety and reliability of the controller.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a blockchain-based multi-controller synchronization method and device in a software-defined network. Background technique [0002] Software Defined Network (SDN) has become an important future network architecture, which decouples the control plane and data plane, and realizes the abstract mapping of the underlying resources. However, as the scale of the network continues to increase, a single controller can no longer meet the needs of the network, and it has become an inevitable trend to realize a logically centralized and physically distributed multi-controller architecture. However, how to realize the information synchronization of multiple controllers is an urgent problem to be solved. [0003] In the prior art, information synchronization methods for multiple controllers mainly include: HyperFlow multi-control architecture utilizes a subscription-publishing model ...
