Problems solved by technology

First, in the case of connecting each branch through an aggregator device and collecting the device information of each branch, the diversity and flexibility of the network hierarchical structure are limited
In addition, as a site selection method, the business type is not considered, but the newly arrived connection request is only processed according to the state of the existing connection and session
This leads to the fact that even though the business types may be different, the load balancing treatment they receive is indistinguishable
For example, services that generate a large amount of network traffic may be allocated to sites that are far away from users, thereby occupying network resources, causing increased network delay, and reducing the service efficiency of the entire hierarchical structure.

Embodiment approach

[0048] 1.1. The overall structure of the hierarchical data center system

[0049] The following comparison figure 1 The overall configuration of the hierarchical data center system according to this embodiment will be described in detail. figure 1 It is a configuration diagram of the hierarchical data center system according to the first embodiment.

[0050] In this embodiment, the hierarchical data center system is composed of a plurality of data centers (ie, sites) connected in a hierarchical manner. Wherein, the connection here only needs to be able to communicate between data centers, and includes various communication connection methods such as wired connection and wireless connection. For example, in figure 1 In , the hierarchical data center system consists of 7 data centers, namely data center 11 101, data center 21 102, data center 22 103, data center 31 104, data center 32 105, data center 33 106 and data center 34 107. They are connected together in a tree topol...

no. 3 approach

[0118] The third embodiment of the present invention will be specifically described below.

[0119] 3.1. Features of the third embodiment

[0120] On the basis of the first embodiment, this embodiment distributes the load traffic not only according to the resource usage status of the data center, but also according to the protocol type of the data packets constituting the load traffic. Hereinafter, only the differences between the present embodiment and the first embodiment will be described in detail, and for the similarities between the present embodiment and the first embodiment, please refer to the description of the first embodiment.

[0121] The structures of the layered data center system and the data center involved in this embodiment are the same as those in the first embodiment, and will not be repeated here.

[0122] Compared with the load balancer involved in the first embodiment, the load balancer in this embodiment further distributes the load traffic transmitte...

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...
