Problems solved by technology

[0005] The present invention provides a method and system for uninterrupted business load balancing that overcomes the above-mentioned problems or at least partially solves the above-mentioned problems. Moreover, the newly added backend instance configuration outside the configuration file cannot be dynamically loaded, so that the business cannot be 100% unaffected, and it cannot take effect in real time.

Embodiment Construction

[0045] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] like figure 1 and figure 2 As shown, the figure shows a load balancing method, including:

[0047] S1. Determine whether the service of the backend instance is available in real time, and update the service status of the backend instance to the service availability list stored in the shared memory;

[0048] S2. Write the updated service availability list into the configuration files of each load balancing device in real time, and persist the configuration files;

[0049] S3. When receiving a user request, select an available backend instance to process the user request according to the service availability list.

[0050] In this example, if image 3 As shown, ...

Abstract

The invention provides a service-uninterrupted load balancing method and system, and the method comprises the steps: S1, enabling a load balancing device to judge whether the service of a rear-end instance is available or not in real time, and updating the service state of the rear-end instance to a service availability list stored in a shared memory; S2, the shared memory writes the updated service availability list into a configuration file of each load balancing device in real time, and persistently stores the configuration file; And S3, when the load balancing device receives the user request, selecting an available back-end instance to process the user request according to the service availability list. Updating the service state of the rear-end instance to a service availability liststored in a shared memory in real time; The shared memory writes the service availability list change information into a configuration file in an asynchronous manner, and notifies other load balancing devices to update related configuration files; The load may be dynamically requested to a backend instance absent in the configuration file without restarting the load balancing device.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a load balancing method and system for uninterrupted services. Background technique [0002] Load balancing refers to the allocation of user traffic accessing the same IP address to different servers according to the pre-configured load balancing algorithm. It distributes user traffic to different servers through virtual service technology, server health check technology and flow-by-flow forwarding technology On the multi-step server, the processing capacity of the server is indirectly improved, and the stability and scalability of the server are also indirectly improved. [0003] With the construction of the third-generation business support, the business support system is developing in the direction of multi-centralization, remoteness, and complexity. The number of hosts has doubled, and the complexity of the system has also increased. Ensuring the cont...
