Embodiment 1

[0038] This embodiment provides a method for providing backup for a software-defined network controller, which is applied to a network system including a switch and multiple controllers. Please refer to figure 1 , showing a flow chart of a method for providing backup for a software-defined network controller, wherein the method for providing backup for a software-defined network controller includes:

[0039] S1. In the initial stage, initialize a network system including a switch and a plurality of controllers, define the plurality of controllers as candidate master controllers, and send a first protocol with a priority attribute among the plurality of candidate master controllers packets, and bind the multiple controllers together to create a virtual controller according to the first protocol, and pre-configure IP addresses and priorities for the multiple controllers and the virtual controller. The first protocol packet is a Virtual Router Redundancy Protocol (VRRP) packet. ...

Embodiment 2

[0052] This embodiment provides a system 1 for providing backup for software-defined network controllers, please refer to figure 2 , showing a physical structure diagram of a system for providing backup for software-defined network controllers. The system 1 for providing backup for software-defined network controllers includes a plurality of controllers 11 and a plurality of switches 12, wherein the plurality of controllers are Controllers 11 are bundled together to create a virtual controller 13. The multiple controllers 11 include a master controller and a backup controller.

[0053] see image 3 , showing a schematic structural diagram of controllers in a system that provides backup for software-defined network controllers, the multiple controllers 11 include a virtual module 110, a sending module 111, a receiving module 112, an extraction module 113, a comparison module 114, and a judgment Module 115.

[0054] Wherein, the sending module 111 is configured to send the f...

Abstract

The invention provides a method for providing backup for a software defined network controller. The method comprises the following steps: in an initial stage, defining a plurality of controllers as candidate master controllers, and transmitting a first protocol message among the candidate master controllers; extracting the priority of the first protocol message; detecting whether the priority of each candidate master controller is higher than that of the first protocol message; if so, defining the candidate master controller as a master controller; transmitting a second protocol message by the master controller; respectively transmitting the first protocol message to each backup controller within a first preset time by the master controller; judging whether each backup controller receives the first protocol message within a second preset time or not; if so, extracting the priority of the message, and continuing to judge whether the priority of each backup controller is higher than that of the first protocol message or not; if not, defining the candidate master controller as the master controller. According to the method and the system, the problems about reliability, expansibility and performance of controllers are solved, and the reliability of network is increased.

Description

technical field [0001] The invention belongs to the field of computer communication networks, and relates to a method and system for providing backup, in particular to a method and system for providing backup for software-defined network controllers. Background technique [0002] SDN (Software Defined Network) network, a new network architecture that separates control and forwarding, makes complex network management much easier. The controller in it is responsible for the centralized control of the entire SDN network. , Improving the delivery of network resources has a very important role. However, as the scale of the network increases, the scalability problems of a single controller become more and more obvious, and the centralization of the control capability of the controller also means that the security and performance of the controller become The bottleneck of the entire network, these single controllers cannot deal with SND network problems across multiple regions, an...
