Industrial backhaul network realizing method and system based on software-defined network

Abstract

The invention discloses an industrial backhaul network realizing method and system based on a software-defined network. The method comprises the strategy distributing/updating stage, the module loading/updating stage and subscription/publication data transmission stage. The system comprises a management server and a data layer device, wherein the management server comprises a user interface unit, a data layer interface unit, a first module updating unit, a first strategy updating unit, a total module library unit, a total strategy library unit, a strategy generation engine unit, a user configuration unit and the like. The data layer device comprises an input information extraction unit, a strategy execution unit, a sub-strategy library unit, a sub-module library unit, a second strategy updating unit, a second module updating unit, a data layer interface unit and the like. By means of the method and system, the subscription/publication network functions can be achieved and updated dynamically and flexibly, and the problems that an existing network is poor in flexibility, high in maintenance cost and hard to update are solved.

Description

technical field [0001] The present invention relates to the field of network technology, and more specifically relates to a software-defined network-based industrial backhaul network implementation method and system. Background technique [0002] Software-Defined Networking (SDN) is currently a new type of network innovation architecture. Since the firmware of traditional network devices (switches, routers) is locked and managed by device manufacturers, SDN hopes to separate network management from physical network topology, thereby getting rid of Hardware constraints on network architecture. In this way, users can modify the network architecture like upgrading and installing software, satisfying enterprises to adjust, expand or upgrade the entire website architecture. The underlying data layer devices, such as switches and routers, do not need to be replaced, which saves a lot of costs and shortens the iteration cycle of the network architecture, providing a good platform ...

AI Technical Summary

Problems solved by technology

When the network scale is large and the number of network devices is large, if it is necessary to change the network or add new functions, it is necessary to manually configure the devices one by one through configuration commands, which is very difficult to operate.

And if the network device itself does not support new functions, it is necessary to replace the device hardware or reprogram the firmware, increasing maintenance costs

Moreover, because the functions of various devices vary widely, batch processing cannot be performed, which increases the difficulty of network maintenance.
