JPH11224235A - How to reduce server load when downloading hypertext data - Google Patents

Abstract

(57) [Summary] An object of the present invention is to perform control from the viewpoint of reducing server load. Upon receiving a request to acquire hypertext data from a client program, a server program interprets a server interpretation language described in advance by a hypertext data creator in the requested hypertext data, and The arrival rate acquired from the arrival rate monitoring program 204 for monitoring the arrival rate of requests to the server program 205 is the server program 2
If the arrival rate exceeds the upper limit of the arrival rate set in advance in the definition of H.05, the description excluding the minimum required image data is removed from the hypertext data. In other cases, all the description capturing the image data is left. The hypertext data is transferred to the client program 203 without changing.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer for providing hypertext data and a method for reducing the load on the computer.

[0002]

2. Description of the Related Art The configuration and operation of a conventional computer system for providing hypertext data will be described with reference to FIG.

In the conventional computer system for providing hypertext data shown in FIG. 1, reference numeral 102 denotes a computer having hypertext data obtained by capturing image data, and 101 denotes a computer which constitutes a server / client environment using 102 as a server. , 103 are application programs capable of downloading / displaying hypertext data, and 104 are
This is an application program that holds / transmits hypertext data that has captured image data.

[0004] Upon receiving a request for obtaining hypertext data from 103, 104 transmits the requested hypertext data to 103, and after interpreting the transmitted hypertext data, 103 takes in the hypertext data. A request for acquiring some image data to be made is made to 104, and 104 has received some requests and transmitted some image data to 103.

Further, as a mechanism for reducing requests to the server, it has been possible to specify not to take in image data by setting a client-side application program in accordance with the convenience of the client-side user.

[0006]

Although the prior art described above may reduce the amount of requests to the server-side application program as a result, it is only a matter of the preference of the client program user, and the server load is reduced. There was a problem that control from a viewpoint was not performed.

An object of the present invention is to reduce the amount of data transmission requests to the server in conjunction with the arrival rate of connection establishment requests to the server from the viewpoint of reducing the load on the server, and at the same time, to minimize the information required on the client side. Is to be transmitted without dropping and to continue to provide necessary information to the client user.

[0008]

According to the present invention, an object of the present invention is to provide an arrival rate monitoring program for monitoring an arrival rate in a server, wherein a creator of the harper text data makes the monitored arrival rate a constant value. When the number of images exceeds the minimum value, it can be achieved by describing in the hypertext data using a server interpretation language so that the image other than the minimum necessary image is not taken in the hypertext data.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 2 is a block diagram for explaining the configuration and operation under a high load in one embodiment of the present invention.

FIG. 3 is a flow chart for explaining the flow of the transmission image data reduction determining process in one embodiment of the present invention.

In FIG. 2, reference numeral 202 denotes a computer having hypertext data obtained by capturing image data; 201, a computer constituting a server / client environment using 202 as a server;
An application program 205 capable of downloading / displaying hypertext data, an application program 205 holding / sending hypertext data having image data taken in, and an application program 204 monitoring the arrival rate of connection establishment requests from an unspecified number of clients to 205 Is an arrival rate monitoring program.

Here, the flow of the transmission image data reduction determining process in this embodiment will be described with reference to FIGS.

An upper limit of the arrival rate of the arrival rate is defined in advance 205 based on the experience value. In addition, the creator of the hypertext data must use the server interpretation language to read the image data necessary for the client-side user to reference the hypertext data. If it exceeds, write it so that it is removed.

Upon receiving the hypertext data acquisition request from the server 203, the server 205 interprets the server interpretation language, and the arrival rate of the connection establishment request monitored by the server 204 exceeds the arrival rate upper limit defined in 205. If it is (307), the description of the unnecessary image capturing part is removed (305), and the hypertext data is transmitted to 203 (306). If there is image data to be taken into the hypertext data by interpreting the transmitted hypertext data 203 (308), the acquisition request is made to 205 and 20
5 receives the request and transmits some image data to 203 (309). If the arrival rate of the connection establishment request monitored by 204 does not exceed the arrival rate upper limit defined in 205 (301), the requested hypertext data is transmitted to 203 as in the conventional processing. Then, the interpreter 203 interpreting the transmitted hypertext data makes a request to 205 to acquire some image data to be taken into the hypertext data, and 205 Send some image data.
(303, 304) Further, examples of images of the hypertext data in the normal state and the load state in one embodiment of the present invention are as shown in FIG.

In FIG. 4, reference numeral 401 denotes an example of an image of hypertext data transmitted to the client when the arrival rate does not exceed the upper limit, and 402 denotes a hypertext transmitted to the client when the arrival rate exceeds the upper limit. It is an image example of data. Image data 403, 404, 405, such as buttons and burners, captured in 401,
Of the 406 and 407, the portion 402 of the hypertext data other than the information 406 (button for linking to a Japanese page in this example), which is indispensable at least, is removed. It should be noted that the determination as to whether or not the image data information is indispensable to the minimum is the determination of the hypertext data creator.

[0017]

According to the present invention, when the load on the resource server is high, the load can be reduced and the required minimum information can be provided to the requester of the hypertext data acquisition.

Claims (1)

[Claims] In a computer having hypertext data loaded with image data and a computer network forming a server / client environment using the computer as a server, the server continuously monitors the arrival rate of a connection establishment request to the server. When monitoring and receiving an acquisition request from a client, the server interprets the description of the server interpretation language written in advance by the creator of the hypertext data in the requested hypertext data and monitors the latest. If the arrival rate is greater than the arrival rate upper limit defined by the server beforehand,
At the point before the server enters the congestion state, the captured part other than the image pasting part, which is the minimum necessary for the user on the client side to interpret the acquired information, is deleted and sent to the client. Mitigation method.
