Highly available load balancing method, system and computer-readable storage medium

Abstract

The invention discloses a high-availability load balancing method, a system and a computer-readable storage medium, which belong to the technical field of communication control. The method includes: a core switch searches for corresponding routing information according to an IP data packet of an access user and a preset routing rule; the core switch determines a corresponding aggregation group according to priority selection conditions between different aggregation groups and the routing information down the routing path pointed to by the route, and send the packet of the user to the routing path, and the aggregation group includes at least one aggregation switch; the aggregation group sends the packet to the corresponding load balancing cluster; the The load balancing cluster sends the packet to the corresponding server and returns the access result according to the user IP, the VIP of the load balancing cluster, and the preset forwarding rule, and the preset forwarding rule includes: inbound and outbound according to preset sources Data structure information is forwarded. The invention improves the reliability of network services, the safety and reliability of equipment.

Description

technical field [0001] The present invention relates to the technical field of communication control, and in particular, to a highly available load balancing method, system and computer-readable storage medium. Background technique [0002] Due to the wide application of various online office, shopping, leisure and entertainment APPs, the Internet and cloud computing have become one of the most popular directions today, and load balancing (LB, Load Balance) has become a key part of the cloud platform network architecture. Taking a typical PTZ architecture in the prior art as an example, as figure 1 As shown, the role of load balancing is to share a large number of client requests to multiple back-end servers for simultaneous processing to improve the performance of cloud services. Early load balancing devices were used by specialized hardware devices, such as F5, A10, Citrix, etc. These devices have high performance and throughput. Most of the deployments adopt the high-av...

Problems solved by technology

Early load balancing devices were made of specialized hardware devices, such as F5, A10, Citrix, etc. These devices have high performance and throughput, and most of them are deployed with active and standby high-availability solutions. When the active is working, the backup device is idle and resources Waste; cluster deployment also appeared later, but not used much
