Problems solved by technology

The browser directly accesses the WEB server according to the IP address entered in the URL address bar. If the current load of this server is high, the access request of the foreground browser will not be processed in time, resulting in slow browser access. The delay is serious, but currently other WEB servers with low load cannot play a role, resulting in a waste of resources

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] A load balancing mechanism for WEB servers in a power dispatching system. A load balancing server is set between the browser group and the WEB server group. Its network topology is as follows figure 1 As shown, it is responsible for monitoring the web server load and balancing the browser access requests, and sending the current access requests to the server with the lowest load for processing, so as to avoid a certain web server with a particularly high load and others to be particularly idle .

[0023] The load balancing mechanism is carried out as follows:

[0024] (1) if figure 2 As shown, the load monitoring module on each WEB server regularly and periodically detects the load of the current WEB server, calculates the load, and transmits the load to the load balancing server. When transmitting the load to the load balancing server, check whether the con...

Abstract

The invention discloses a load balancing mechanism for a Web server in an electric power scheduling system. The load balancing mechanism adopts the steps as follows: (1) periodically detecting load condition of the current WEB server by a load monitoring module of every WEB server, and calculating the load capacity; (2) receiving and comparing the current load capacities of servers by a load balancing server, selecting the server with lowest server as a to-be-visited Web server, and writing the IP address of the selected server into a shared memory file; and (3) receiving an access request of a browser by the load balancing server, reading the IP address of the to-be-visited Web server in the shared memory file, if the read IP address exists, sending the access request to the to-be-visited Web server for processing, and if the read address does not exist, sending the access request to a default server for processing. The load balancing mechanism provided by the invention has the advantages of high reliability and usability, network resource conservation, and strong universality.

Description

technical field [0001] The invention relates to a load balancing mechanism of a WEB server, more specifically, relates to a load balancing mechanism of a WEB server in a power dispatching system, and belongs to the technical field of computer networks. Background technique [0002] The three-zone WEB servers configured in the current power dispatching D5000 system generally have two or more WEB servers configured to provide WEB services to the outside world in a peer-to-peer manner. The browser directly accesses the WEB server according to the IP address entered in the URL address bar. If the current load of this server is high, the access request of the foreground browser will not be processed in time, resulting in slow browser access. The delay is relatively serious, but currently other WEB servers with lower loads cannot play a role, resulting in waste of resources. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in th...
