Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 Shown is a work flow diagram of a cluster load balancing method of the present invention, including:

[0031] Step S101, including: updating the load information of each node in the cluster every preset period, and selecting a scheduling set including multiple light-load nodes in the current period according to the load information of each node in the cluster;

[0032] Step S102, comprising: receiving an access request, analyzing the access request, and determining whether the access request is a dynamic request or a static request;

[0033] Step S103, including: if the access request is a dynamic request, select a node from the scheduling set of the period in which the access request is located through a random algorithm as the processing node of the access request, and if the access request is a static request...

Abstract

The invention discloses a load balancing method and system for a cluster. The method comprises the following steps: updating the load information of each node in the cluster at a preset interval, and selecting a scheduling set including a plurality of light load nodes in a current period; resolving an access request, and determining that the access request is a dynamic request or a static request; if the access request is the dynamic request, selecting a node from the scheduling set of the period in which the access request is positioned through a random algorithm for serving as a processing node of the access request; and if the access request is the static request, inquiring a URL (Uniform Resource Locator) mapping table, taking a node corresponding to the mapping record of a URL corresponding to the access request as the processing node of the access request if the mapping record exists in the URL mapping table, and selecting a node through a random algorithm if the mapping record of the URL corresponding to the access request does not exist in the URL mapping table for serving as the processing node of the access request. Through adoption of the load balancing method and system, load balancing is ensured. Meanwhile, the load of the cluster is adjusted periodically, so that node overload is prevented.

Description

technical field [0001] The invention relates to the technical field related to network clusters, in particular to a cluster load balancing method and system. Background technique [0002] The rapid increase of the scale of Internet users and the form of WEB applications has brought many challenging problems to the servers supporting WEB applications.
