Abstract

The invention relates to a load balancer, a load balancing method and a stratified data center system. The load balancer is used in the stratified data center system which is formed by connecting a plurality of data centers in a stratified mode, and is used for distributing flow of a present data center load which is transmitted to the data centers and corresponds to the load balancer. The load balancer is used for distributing the load flow transmitted to the present data centers according to the resource using state of the present data centers and the resource using state of the lower layer data centers. According to the load balancer, the load balancing method and the stratified data center system, structural diversity and flexibility of the stratified data center system can be improved, the data center with the position close to a user and with spare resources is selected as far as possible to process the request of the user according to the resource using state of the data centers by which the stratified data center system is formed, load of the stratified data center system can be balanced, response speed of a user request is improved, and service efficiency of the stratified data center system is improved.

Description

technical field

[0001] The invention relates to data center load balancing technology, in particular to a load balancer for load balancing between subnets of a layered data center system, a load balancing method, and a layered data center system using the load balancer and the load balancing method. Background technique

[0002] Currently, hierarchical data center systems are widely used in network applications, especially in the growing Internet of Things applications. In order to improve the service efficiency of such a layered system, load balancing among its subnets is required.

[0003] The following technology is mentioned in Patent Document 1, that is, using an aggregator device to provide aggregation and load balancing of branch office devices in a hierarchical manner and in a manner that reduces branch office (ie, hereinafter referred to as site or data center) device configuration . Through the interaction between the aggregator devices, the device information of...
