Embodiment Construction

[0017] Please refer to figure 1 , figure 1 A schematic diagram of a system architecture of a dual-controller system operated by the load balancing method of the dual-controller system of the present invention. like figure 1 As shown, since the present invention adds a traffic statistics module 10, a load distribution module 20 and a communication module 30 between the two controllers C0 and C1 of the same dual-controller node, when accepting a task, the system will first compare the two The load status on the two controllers C0 and C1, and then perform load balancing processing and synchronize information.

[0018] In a dual-controller system, both controllers C0 and C1 have their own MAC addresses. Even under the separate control of the same controller, more than one MAC address is allowed due to different binding modes. Therefore, one of the purposes of the present invention is to firstly solve the conflict problem of different MAC addresses and the same IP address.

Abstract

The invention discloses a load balancing method for a dual-controller system, particularly the load balancing method for the dual-controller system using a public Internet protocol (IP) address. By the method, the load conditions of two controllers are compared at first, load balancing processing is performed and information is synchronized, so the problems of conflicts formed by different media access control (MAC) addresses and an identical IP address in the dual-controller system in the prior art can be solved, and failover also can be partially performed according to the central processing unit (CPU) occupancy rate of a network for each controller and the CPU vacancy rate of each controller to realize the high-efficiency virtualization service of the dual-controller system.

Description

technical field [0001] The invention relates to a load balancing method of a dual controller system, in particular to a load balancing method of a dual controller system using public IP addresses. Background technique [0002] A computer cluster, referred to as a cluster (Cluster), is a collection of many servers that work together to provide high-availability resources. Just as redundant components can protect users from hardware failures, clustering technology can protect users from the breakdown of the entire system and failures at the operating system and application levels. A server cluster includes multiple servers with shared data storage space. Each server is usually called a node, and the servers are connected to each other through a local area network; when one of the servers fails, the application it runs The program will be automatically taken over by the server connected to it. Clustering isn't just about providing longer uptime, it's also important in minimiz...
