Abstract
Embodiments of the present disclosure provide a software defined network publish-subscribe system and method. The software defined network publish-subscribe system comprises a controller, an administrator controller, a sequencing subsystem and a message multi-backup cache subsystem. The controller is configured to process publish-subscribe transactions in clusters, and comprises sequencing nodes used for generating ordered serial numbers for messages and cache nodes for caching the messages. The administrator controller is configured to simultaneously perform functions of the controller and manage software-defined network. The sequencing subsystem is configured to realize the cooperative sequencing between the administrator controller and the sequencing nodes. The message multi-backup cache subsystem is configured to realize the consistency of the messages through the administrator controller and the cache nodes. Through the interaction of various modules, the consensus of various subscribers on the messages and the message serial numbers is realized on the software defined network publish-subscribe system.
