In order to understand the technical features, content and advantages of this creation and its achievable effects, this creation is combined with the diagrams, and detailed descriptions are given in the form of embodiments as follows, and the diagrams used therein have only To illustrate and supplement the manual, it may not be the true proportions and precise configuration after the implementation of this creation. Therefore, the proportion and configuration relationship of the attached drawings should not be interpreted or limited to the scope of rights of the creation in actual implementation. In addition, in order to facilitate understanding, the same elements in the following embodiments are denoted by the same symbols.

The web server load balancing method of this creation includes the following technical means:

(1) The core of a dynamic web page is to use a database to store web page data, and the web page is sent to the browser through the real-time "interpretation" process on the host side. The method is converted into standard HTML grammar and sent to the user’s browser, so the load of dynamic web pages on the web host will be relatively large, because the host does not only send HTML files, but needs to do a lot of processing before sending the HTML Send out.

In website design, webpages in pure HTML (an application under the standard Universal Markup Language) format are usually called "static webpages". Static webpages are standard HTML files whose file extensions are .htm and .html. Contains text, image, sound, FLASH animation, client script and ActiveX control items and JAVA applets. Static web pages are the basis of website construction. Early websites were generally made from static web pages. Static webpages are relative to dynamic webpages. They refer to webpages that have no back-end database, no programs, and no interaction.

Static web pages are sometimes called flat pages. The URL form of a static webpage usually ends with htm (hypertext markup language), and also ends with hypertext markup language (.htm, .html), .shtml, .xml (extensible markup language), etc. On hypertext markup language format webpages, various dynamic effects can also appear, such as animation in .GIF format, FLASH, rolling subtitles, etc. These "dynamic effects" are only visual, and are different from the dynamic webpages that will be introduced below. the concept of. A static web page is usually a hypertext markup language document stored as a file in the file system, and the web server can be accessed via HTTP.

(2) The user group browses or queries the company website, and the web interface processor divides the work requirements into static work and dynamic work and enters the work queue.

(3) The allocator will enter information from three parties, 1 is the work queue requirement, 2 is the load balancing algorithm, and 3 workstation information for the allocator to select and enter the workstation for processing.

(4) The load balancing algorithm is based on the work group (static or dynamic, with high static weight) (or with high dynamic weight) and the queue time (the longer the weight, the greater the weight). Make the whole system work better.

(5) The workstation group will have information showing whether the workstation is busy or idle. The busy workstation will internally assign another workstation to help with the work requirements.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of the web server load balancing method of the present invention. As shown in FIG. 1, the load balancing method for a web server of the present invention includes: using a web interface processor 10 to classify a plurality of jobs A (work A, job B...work N) into static jobs or dynamic jobs, and enter dynamic jobs Work queue or static work queue; load balancing algorithm is used to perform weight calculation based on the work group to which the work A belongs and the time in the dynamic work queue and the static work queue to obtain the work A plurality of weighted requirements; and according to the weighted requirements of the tasks A and the plurality of workstation information, the distributor 20 assigns the tasks A to the plurality of workstations 30 (Workstation 1, Workstation 2, Workstation 3...Workstation N) .

The workstation information includes a plurality of status information of the workstations 30.

The status information indicates that the workstations 30 are in a busy state or an idle state.

The allocator 20 first receives the needs of the jobs A in the dynamic job queues and the static job queues, and then uses the load balancing algorithm according to the job group to which the jobs A belong and in the dynamic jobs The time in the queue and the static work queues are weighted to obtain the weighted demands of the work A.

The weights of the tasks A in the dynamic task queues are preferably higher than the weights in the static task queues. Alternatively, the weights of the jobs A in the static job queues may also be higher than the weights in the dynamic job queues.

The longer the time of the jobs A in the dynamic job queues and the static job queues, the greater the weight.

A plurality of users browse or query a website, so as to generate the requirements of the tasks A to the web interface processor 10.

The static task is to browse or query web pages without a back-end database, without programs, and without interactivity. The dynamic task is to browse or query web pages with background databases, programs, and interactions.

In summary, according to the web server load balancing method of the present invention, it can have one or more of the following advantages: (1) With the web interface processor, work requirements can be divided into static work and dynamic work, and enter Work queue. (2) The allocator can select work into the workstation for processing according to the work queue requirements, load balancing algorithm and workstation information.
