Problems solved by technology

In the current technology, two schemes are usually used to check the validity of nodes: one is to perform high-frequency validity checks, which will consume a lot of unnecessary resources and even overwhelm some already busy nodes; Another method is to increase the cycle of health checks. Although this reduces resource consumption, it will lose the timeliness of node checks.

Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0054] figure 2 is a flowchart of a load balancing method provided by an embodiment of the present invention, such as figure 2 As shown, the methods include:

[0055] S1, cyclically check the validity of each node among the plurality of nodes, and identify the node as a valid node or a failed node. The node mentioned here may be a server (server), on which an application is installed, and whether the server node is valid is determined by checking whether the application on the server can successfully provide services. In this embodiment, if the node is detected to be valid for 3 consecutive times, the node is identified as a valid node, and if the node is detected to be invalid for 4 consecutive times, the node is ide...

Abstract

The invention provides a load balancing method and system. After checking the validity of a node each time, the probability that the state of the node is unchanged is calculated when the node is checked next time, and according to the probability, the time interval between this time node checking and next-time node checking is calculated, so that the time interval of node checking can be dynamically changed, therefore, for the nodes with unchanged validity status, the adaptability reduces the checking frequency and reduces the resource consumption required for checking; and for the nodes with changed validity, the adaptability improves the checking frequency and ensures the real-time performance of checking.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a load balancing method and system, which are used to realize the load balancing of flow among multiple nodes. Background technique [0002] In large Internet companies, applications are deployed on many nodes. In order to achieve load balancing among these nodes, it is necessary to distribute traffic to these nodes. Existing technologies such as figure 1 As shown, the load balancing cluster is used for node distribution. The load balancing cluster is composed of multiple load balancers (for example, haproxy, nginx), each load balancer is connected to each node, and the load balancer can forward the user's request To the application on the node, and return the execution result of the application on the node to the user. [0003] The load balancer needs to perform regular validity checks on the backend nodes to ensure that the nodes are valid. In the current techn...
