Abstract

PROBLEM TO BE SOLVED: To provide a better response to a specific priority user than to general users in a system to be accessed by many and unspecified users through a network. SOLUTION: The system is provided with a device for detecting entering/ leaving of the priority user to/from a store and instructing the registration/ deletion of a condition for preferentially processing the user to a priority controlling mechanism. The priority processing is performed according to small number of conditions for distinguishing the priority user to be given priority processing presently from other general users. This system has a constitution different from conventional techniques where many conditions concerning the user to be handled as the priority user are previously and fixedly registered to perform the priority processing based on them. Thus, even when many and unspecified users access to the system, a better response is provided to the specific priority user than to the general users.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system in which an unspecified number of users access via a network, such as an electronic commerce system, and more particularly to a system in which server resources are preferentially allocated to specific priority users. The present invention relates to a system that can provide a service to a specific priority user with a better response than a general user.

[0002]

2. Description of the Related Art In an e-commerce service for an unspecified number of Internet users as currently performed, unexpected sudden access is concentrated, and competition of server resources such as computer resources and network bandwidth occurs. As a result, there is a problem that the response as viewed from the user is deteriorated and the business is hindered.

The response from the viewpoint of the user of the electronic commerce service is governed by a plurality of factors such as the congestion of server equipment and the Internet, and the state of the client terminal.
The most likely bottleneck as a result of the sudden concentration of access to one site is the computer resources that provide the service. For example, I /
An increase in the CPU usage rate due to the O or CGI process causes a decrease in response.

Another resource that is likely to be a bottleneck is a server connection line for connecting server equipment to the Internet. When there is a server that provides content having a large amount of information such as an image, the bandwidth of a network for sending the content to the Internet may be insufficient, which may lead to deterioration of a response as viewed from a user.

[0005] There has conventionally been a mechanism for preferentially allocating computer resources and network bandwidth to transactions and communications under specific conditions. For example, regarding the network bandwidth, there is a C band controller such as the Access Point series provided by Lucent Technologies.

In this apparatus, the conditions of the communication to be prioritized are fixedly described in advance in the apparatus. These conditions include the IP address, domain name, and protocol type of the transmitting / receiving terminal. These communication conditions are fixedly written in an internal memory of the apparatus by an administrator.

[0007] If such a band control device is used, for example, a server A, a server B, and a server C are added to a server farm.
If there are two servers, it is possible to evenly allocate the network bandwidth among these servers. this is,
This is useful for hosting services.

A problem in applying such a priority control technique to an electronic commerce service is that it is difficult to register the conditions of the priority user in advance. Because B2C for unspecified number of Internet users
This is because in the type of e-commerce service, the number of potential users is almost infinite, and it is impossible to permanently store the conditions of the priority users in the band control device in advance.

For example, it is assumed that the IP address of the priority user is used to identify the priority user in the above-mentioned Access Point series bandwidth control device. However, in a band control device, the number of classes describing communication conditions is several hundred at the maximum, and it is not possible to register all priority users.

There is a similar problem with computer resources.
A nice command in UNIX (registered trademark) or a setpriority () system call exists, and the priority of a process can be designated. By using this mechanism, it is possible to give a specific priority to a process satisfying a specific condition.

However, when this mechanism is applied to an electronic commerce service, the same problem as that of the above-mentioned band control device occurs. That is, it is almost impossible to register the conditions of the priority user in advance and give priority to the process activated by the user because the number of priority users is potentially infinite.

As described above, it is difficult to apply the conventional priority control technology to an e-commerce service for an unspecified number of users as it is and to perform priority control by identifying a priority user on a user-by-user basis. is there.

The most important reason is that these priority control devices have a large overhead when performing priority processing while storing a large number of priority conditions, which makes priority processing practically impossible. is there.

In the example of the band control device, if 2000 priority users are registered, the user who has just come
Checking, on a packet-by-packet basis, which of the 000 matches would significantly reduce the performance of the device. Moreover, the number of packets issued in one electronic transaction requested by the user is usually several hundreds or more, which further exacerbates this problem.

[0015]

SUMMARY OF THE INVENTION The present invention relates to a system in which an unspecified number of users access via a network such as an electronic commerce service, when a priority is given to a specific priority user. This is to solve the above-mentioned problems.

That is, like a conventional priority processing device,
In a system in which the conditions for identifying priority users are fixedly stored inside the device, priority processing is implemented in e-commerce services for Internet users targeting an unspecified number of users. I can't.

The present invention solves the above-mentioned problems, and in a system where an unspecified number of users access via a network such as an e-commerce service, a specific priority user is better than a general user. The purpose is to provide technology that can provide a response.

[0018]

SUMMARY OF THE INVENTION The present invention has a function of allocating resources preferentially in a system accessed by an unspecified number of users via a network, and using the function to provide services to users. Control means for controlling provision; storage means for storing priority information assigned to the user; and, according to the priority information stored in the storage means, whether or not the user of the access request is a priority user. When judging that the user is the priority user, the first instruction means instructing the control means to perform the priority processing of the user, and detecting whether or not the service provision to the user performing the priority processing is ended. When detecting the end of the service provision, the control unit instructs the control means to stop the priority processing for the user. Configured to include an indicating means.

According to the present invention having the above-described configuration, the first instructing means determines that the user of the access request determines that the user is a priority user when logging in.
The second instruction means instructs the control means to give priority to the user, and when the second instruction means detects the end of service provision to the user to be given priority processing, the second instruction means instructs the control means to give priority to the user. Instruct them to stop.

In response to the instructions from the first and second instructing means, the controlling means determines based on only the dynamically instructed conditions for the priority user who must perform the current priority processing.
Priority processing for the priority user (priority processing such as priority / non-priority, priority processing according to priority, etc.) is executed.

As described above, according to the present invention, in order to realize priority control of an unspecified number of users, based on a small number of conditions for distinguishing a priority user who must currently perform priority processing from another general user. A configuration in which a very large number of conditions regarding a user to be treated as a priority user are fixedly registered in advance as in the prior art, and a very large number of fixedly registered Priority processing is not performed based on the above conditions, so that in a system accessed by an unspecified number of users, it is possible to provide a better response than a general user to a specific priority user. become able to.

Next, the present invention will be described in more detail with a specific example applied to a system for realizing an electronic commerce service.

When realizing an electronic commerce service according to the present invention, in addition to a device for providing a series of functions for providing a basic electronic commerce service such as a WWW server, a customer DB, and a product DB, the priority of each registered user is given. A customer database (corresponding to the storage means described above) that records the degree of access, determines whether the accessing user is a registered priority user, and, if the user is a priority user, notifies the scheduler of the priority user. A priority user authentication unit (corresponding to the above-described first instruction means) for instructing the scheduler to perform priority processing, detecting that the priority user has finished using the service and leaving, and instructing the scheduler to give priority to the priority user. A priority user condition deletion unit (corresponding to the above-mentioned second instruction means) for notifying the user of the priority, when a server resource conflict occurs, An electronic commerce service is provided by a system including a scheduler (corresponding to the above-described control means) that determines a service execution order in accordance with the service execution order and executes the service according to the execution order.

Here, the scheduler is provided with a "list of priority users existing in the system at each point in time" which is held and managed in a memory.

When the electronic commerce service is realized by the present invention, the most important thing is to provide a device for detecting arrival / departure of a priority user and instructing a priority control mechanism to register / delete a condition for preferentially processing the user. Features. The difference from the prior art is that the condition for identifying the priority user is dynamically set in the priority control mechanism.

In the e-commerce service realized by the present invention configured as described above, the scheduler that controls the server resources gives priority to the priority user according to the condition notified from the priority user authentication unit. Therefore, the priority user can preferentially use the server resources.

On the other hand, the priority user authentication unit and the priority user condition deletion unit detect the arrival / departure of the priority user and dynamically register or delete a condition for giving priority to the user to the scheduler.

Accordingly, the priority control mechanism in the system can execute the priority processing based on the minimum number of conditions at each time.

As a result, the scheduler can substantially perform priority processing for an unspecified number of users, and the object of the present invention is to provide electronic commerce for an unspecified number of users. , Priority control can be performed.

To reiterate, according to the prior art, in order to control the priority of an unspecified number of users, it is necessary to register a very large number of conditions in the scheduler in advance. However, there is a problem that the performance of the priority control mechanism itself deteriorates when processing is performed based on this condition.

On the other hand, according to the present invention, the priority control mechanism sets the priority user based on a small number of conditions for distinguishing the priority user (priority user currently visiting the store) at each time from other general users. Since the processing can be performed, the priority processing can be performed without deteriorating the performance of the priority processing.

For example, according to a conventional technique, as shown in FIG. 1A, according to a conventional technique, as shown in FIG. 1A, based on a very large number of fixedly registered conditions, According to the present invention, as shown in FIG. 1B, a very small number of conditions for dynamically registered preferential users who are currently visiting the store are required. , It is sufficient to perform the priority control of the bandwidth control, so that the priority control for an unspecified number of users can be performed.

Although the priorities described above are two levels of priority or non-priority, the scope of the present invention is not limited to two levels of priorities. As shown in FIG. 1, it is possible to provide a plurality of priority classes, for example, three levels, and perform exactly the same processing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail according to embodiments.

FIG. 2 shows a first embodiment of the present invention.

In the first embodiment, "priority processing by network bandwidth control" in the electronic commerce service is assumed.

In the figure, 1 is an electronic commerce system equipped with the present invention, 2 is a terminal operated by a priority user or a general user,
Reference numeral 3 denotes the Internet connecting the electronic commerce system 1 and the terminal 2.

The electronic commerce system 1 having the present invention includes a business server 10, a customer authentication server 11, a bandwidth control mechanism 12, a priority user authentication unit 13, and a priority user condition deletion unit 14.

The business server 10 includes a WWW server, a decision making server, and a search engine to provide an electronic commerce service. The customer authentication server 11 includes a customer database 15 that manages user information of each registered user, and executes a process of authenticating a user who has made an access request.

This customer database 15 manages the priorities assigned to each registered user as shown in FIG. 3 in order to realize the present invention. The priority may be a value indicating no priority or a value indicating the degree of priority.

The bandwidth control mechanism 12 is provided in the middle of the line connecting the server equipment to the Internet, and implements the CBQ algorithm to guarantee the minimum bandwidth to the priority user. In this CBQ algorithm,
A class can be defined according to communication conditions (for example, the address of a sender / receiver), and a minimum bandwidth can be guaranteed for communication belonging to the class.

The bandwidth control mechanism 12 functions as a scheduler for determining the service execution order according to the priority of each user when server resources conflict, and executes the service in accordance with the determined execution order. It has a function as a priority control mechanism.

The priority user authentication section 13 is provided with the band control mechanism 1
For 2, the user dynamically sets the user who visits the store as a priority user and the priority method to be given to the priority user (determined according to the priority managed in the customer database 15). That is, as shown in FIG. 4, a user who comes to the store is treated as a priority user, and a priority method for the priority user is set.

The priority user condition deletion unit 14 dynamically deletes the priority condition information for the priority user from the bandwidth control mechanism 12 when the priority user registered in the bandwidth control mechanism 12 leaves. That is, as shown in FIG.
When the priority user leaves, the priority condition information for the priority user set by the priority user authentication unit 13 is dynamically deleted.

(1) The customer authentication server 11 refers to the customer database 15 when a user logs in, and the user is a priority user (a user having a priority indicating the assignment of priority processing). If it is determined that the user is the priority user, the priority user authentication unit 13 is notified of the fact that the priority user has visited the store and the priority of the priority user.

(2) Upon knowing that the priority user has visited the store according to the notification from the customer authentication server 11, the priority user authentication unit 13 acquires the IP address of the user from the WWW server.

That is, the user accesses the WWW server, inputs an IP address and a password, and
It is transmitted to the server, and upon receiving this, the CGI program that receives it starts on the WWW server.
At that time, the IP address of the user is obtained from the WWW server process.

(3) The priority user authentication unit 13
For example, the bandwidth specified by the priority notified from the customer authentication server 11 is specified such that 128 kbps is assigned to the priority A, 32 kbps is assigned to the priority B, and 8 kbps is assigned to the priority C.

The priority user authentication unit 13 creates one class for the communication defined by the pair of the IP address of the priority user and the IP address of the server, and sends a class to the bandwidth control mechanism 12. The created class is notified to guarantee the specified band. Specifically, the priority user authentication unit 13 sends the bandwidth control
This process is performed by establishing a session using a protocol such as P and transmitting a command for setting a priority class.

(4) In response to the instruction from the priority user authentication unit 13, the bandwidth control mechanism 12 creates a class relating to the priority user who has logged in, and performs priority processing.

(5) The priority user condition deletion unit 14 detects that the priority user has finished using the service and has left, by receiving a notification from the business server 10.

Specifically, the priority user clicks a logout button on the browser to leave the store. By clicking this button, the CGI program starts on the WWW server side, and informs the priority user condition deletion unit 14 that the user will leave, so that the priority user condition deletion unit 14 It detects that you are leaving.

(6) The priority user condition deletion unit 14 subsequently notifies the band control mechanism 12 to delete the class for the departed priority user created in the above (4). More specifically, this processing is performed by establishing a session to the bandwidth control mechanism 12 using a protocol such as TCP and transmitting a command for deleting a priority class.

(7) Upon receiving the instruction from the priority user condition deleting unit 14, the band control mechanism 12 deletes the class.

FIG. 5 shows a schematic processing flow of the processing performed in the first embodiment.

As shown in this processing flow, in the first embodiment, when the user who comes to the store is a priority user, the priority user authentication unit 13 performs class processing on the communication of the priority user according to the processing of the priority user authentication unit 13. Is dynamically set in the bandwidth control mechanism 12 so as to guarantee a bandwidth according to the priority of the priority user, and when the priority user leaves, the priority user condition deletion unit 14 The communication class set for the priority user is dynamically deleted from the band control mechanism 12 according to the processing of the band control mechanism 12 so that the band control mechanism 12 determines the band based on the priority control information assigned only to the priority user who is currently visiting the store. Processing is performed so that priority processing of control can be performed.

As described above, according to the first embodiment, priority control for an unspecified number of users can be realized when executing priority processing by network bandwidth control in the electronic commerce service. .
