Title:
SOFTWARE-DEFINED NETWORK PUBLISH-SUBSCRIBE SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/212726
Kind Code:
A1
Abstract:
Provided in the present invention are a publish-subscribe system and method for a software-defined network. The system comprises: a controller, an administrator controller, a sequencing subsystem, and a message multi-backup cache subsystem. The controller is used for processing publish-subscribe transactions in a cluster, comprising a sequencing node used for generating sequential serial numbers for messages and a caching node used for caching the messages. The administrator controller is used for simultaneously undertaking the functions of the controller and used for managing the software-defined network. The sequencing subsystem is used for implementing collaborative sequencing between the administrator controller and the sequencing node. The message multi-backup cache subsystem is used for maintaining the consistency between messages going through the administrator controller and messages of the cache node. The present invention, by means of interactions between various modules, implements the consensus and consistency of subscribers with respect to messages and message serial numbers on a publish-subscribe system of an SDN.
