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 content is provided from a Web server to a user terminal via a communication network such as the Internet, from when a user desires to provide content until when the content is provided. The present invention relates to a web service response time measuring system and a measuring server for measuring time.

[0002]

2. Description of the Related Art A system is widely used in which contents such as images, videos, and sounds (hereinafter, also referred to as Web contents) are provided from a Web server to a user terminal via the Internet. In such a system, measuring the time (response time) from when the user operates the web browser on the user terminal to provide the content until when the content is displayed or started to be reproduced on the user terminal. Web that provides content to users via the Internet
Understanding the quality of service is important for the success of Web service business.

The measured response time is as a measurement result,
For example, it is stored in a measurement server that can be connected to the Internet. Then, the measurement result can be used to grasp the tendency of the response time for each content or each content group including a plurality of related contents, or the tendency of the response time for each user or each user group including a plurality of related users. It is used for grasping. A user group consisting of a plurality of related users is, for example, 1
A user operating a user terminal that belongs to one LAN and is connectable to the Internet via a router or the like.

The following two techniques are available for measuring the response time.
Two schemes are known.

(1) A device called a probe for monitoring a packet monitor type packet is connected to a communication network between a Web server and a user terminal, and a response time is calculated from a difference between passing times of a request packet and a reply packet. In this method, the calculated response time is accumulated in the measurement server as the measurement result.

(2) Measurement module type A measurement program for response time measurement is installed in advance in the user terminal. The measurement program is Web
The time when the request data is sent from the browser and the time when the display of the content is completed (in the case of an image) are monitored, and the response time is measured from the difference between the time of sending and the time when the display is completed. Then, the measured response time is transmitted as measurement data from the user terminal to the measurement server via the communication network,
This is a method of accumulating measurement data in a measurement server.

When the packet monitor type system is used, it is necessary to install one or several probes in the communication network, but there is an advantage that new communication traffic is not generated for measuring the response time. is there. However, it is not possible to understand the decrease in responsiveness caused by the processing on the Web browser side such as the display processing.

Therefore, in order to accurately measure the response time in the Web service providing system, it is necessary to use the measurement module type method. FIG. 10 is a flowchart showing a processing example of a conventional measurement module type Web service response time measuring system. A user uses a Web site on a user terminal (hereinafter referred to as a client).
When the browser is activated and an operation for requesting the provision of content is performed (step S100), the web browser transmits request data to the web server that provides the content (step S101). Further, the measurement program starts measuring the response time (step S102).

Upon receiving the request data from the client (step S110), the Web server performs a process of creating the content to be provided to the user (step S111), and transmits the created content to the client (step S113). Upon receiving the content, the client displays the content (when the content is an image: step S103). The measurement program is
When the completion of displaying the content is detected, the response time measurement ends (step S104). Then, the measured response time is transmitted as measurement data to the measurement server (step S107).

Upon receiving the measurement data from the client (step S115), the measurement server stores the measurement data in the database (step S116).

[0011]

As described above, in the conventional web service response time measuring system, each client transmits the measurement data to the measuring server each time the web is accessed. Then, many clients independently
And in an environment where Web service requests are made irregularly,
Measurement data may be simultaneously sent from many clients to the measurement server. When a large amount of measurement data that exceeds the processing capacity of the measurement server arrives at once, congestion occurs in the transmission / reception processing of measurement data, and the communication traffic due to measurement data impedes the traffic for the original data communication. is there. Further, there is a problem that the process of transmitting the measurement data increases the load on the client.

It should be noted that each client transmits measurement data to the measurement server each time it makes a Web access, at a timing different from Web access when a dial-up line or the like exists in the communication network between the client and the measurement server. This is because if the measurement data is transmitted in, a new communication cost for reconnecting the line is generated separately from the web access.

The present invention is an invention for solving the above-mentioned problems, and does not increase communication traffic for measuring response time even if a large number of user terminals simultaneously access the Web, Another object of the present invention is to provide a web service response time measurement system and a measurement server that do not increase the load on the measurement server.

[0014]

A response time measuring system for a Web service according to the present invention measures and measures the time from when a user terminal desires to provide Web content through a communication network until it obtains Web content. A response time measurement system for a Web service that transmits data to a measurement server, characterized in that the measurement server includes a regulation unit that regulates simultaneous transmission of measurement data from a plurality of user terminals.

The regulation means in the measurement server is, for example,
If one user terminal wants to provide content,
When the total allowable number of measurement data transmissions already allowed to other user terminals has not reached the predetermined value, the measurement data is controlled to allow one user terminal to transmit the measurement data. It is configured to include a transmission instruction unit. With such a configuration, it is possible to regulate the number of simultaneous transmissions of the measurement data from each user terminal to a predetermined value.

The measurement server registers a transmission instruction list table in which the measurement data transmission allowable number permitted by the user terminal is registered, and a hold instruction list table in which the number of measurement data transmission opportunities not permitted by the user terminal is registered. The measurement data transmission instructing unit has a predetermined predetermined total number of measurement data transmissions permitted by another user terminal when one user terminal desires to provide the content. When the value has reached the value, the number of measurement data transmission opportunities corresponding to one user terminal in the suspension instruction list table may be increased by one. According to such a configuration, the measurement server performs control to cause the user terminal to transmit the measurement data that has been suspended from transmission, based on the number of measurement data transmission opportunities registered in the suspension instruction list table. Will be possible.

When one user terminal desires to provide the content, the measurement data transmission instructing section sets the total number of measurement data transmissions already permitted to other user terminals to a predetermined value. If the measurement data transmission opportunity corresponding to the one user terminal in the suspension instruction list table is registered when the number has not reached, the one user including the number of times corresponding to the number of registered measurement data transmission opportunities It may be configured to allow the terminal to transmit the measurement data. According to such a configuration, the measurement server can cause the user terminal to transmit the measurement data whose transmission has been suspended, and then transmit the measurement data, and the measurement result of the response time measured by the user terminal is not wasted.

The regulation means may be configured to control the user terminal so that information that can specify the allowable number of measurement data transmissions is supplied together with the content. With such a configuration, the user terminal can sequentially recognize whether to transmit or hold the measurement data.

The user terminal has, for example, a response measuring means for measuring the time from when the content is desired to be provided until the content is obtained, and a process of transmitting the response time measured by the response control unit as measurement data to the measurement server. And a measurement data transmission control means for performing the measurement data transmission control means, when the measurement data transmission control means indicates that the measurement data transmission allowable number is 0, the transmission of the measurement data is suspended. When the information that can specify the measurement data transmission allowable number indicates the measurement data transmission allowable number of 2 or more, the suspended measurement data is also transmitted. With such a configuration, the user terminal can suspend the transmission of the measurement data, and can transmit the suspended measurement data after releasing the suspension.

The measurement server according to the present invention is a measurement server that receives from a user terminal, as measurement data, the time from when the user terminal desires to provide the content through the communication network until when the content is obtained,
It is characterized in that a regulation means for regulating the simultaneous transmission of measurement data from a plurality of user terminals is provided.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of the configuration of a response time measuring system for Web services according to the present invention. In the system illustrated in FIG. 1, user terminals (clients) 3a, 3 such as personal computers.

It is possible to connect to the Internet 6 via.

The measurement server 1 and the Web server 2 are LAN
Connected to the Internet 6 via the router 5c.

FIG. 2 is a block diagram showing a configuration example of the clients 3a to 3e, the measurement server 1 and the Web server 2 and a connection relationship. In FIG. 2, clients 3a-3
e is referred to as the client 3. Further, hereinafter, when referring to any one of the clients 3a to 3e, or when referring to all of the clients 3a to 3e, the client 3 is referred to. The clients 3a to 3e
May have the same configuration.

In the example shown in FIG. 2, the client 3 has
The web browser 31 is installed, and the client 3 includes a measurement module. The measurement module is
A response measurement unit 32 that measures a response time, and a measurement data transmission unit 33 that performs a process of transmitting the response time measured by the response measurement unit 32 as measurement data to the measurement server 1.
Including and The response measurement unit 32 is realized by a program installed in the client 3 in advance. In addition, the measurement data transmission unit 33, for example, a program that determines whether or not to transmit the measurement data,
It is realized by a communication control program and a LAN card.

The Web server 2 includes a Web server processing unit 21 for selecting the content requested by the client 3 from the content database 22 storing various contents and transmitting the selected content to the client 3.

The measurement server 1 includes a measurement data collection unit 11 for receiving the measurement data transmitted by the client 3, a measurement data collection database 12 for storing the measurement data received by the measurement data collection unit 11, and a Web server 2. W
Measurement data transmission instruction unit 1 for instructing the eb server processing unit 21 to transmit measurement data transmission instruction information
3 and a measurement data transmission instruction management table 14 that stores management information. Measurement data transmission instruction management table 1
Reference numeral 4 denotes a storage area formed in the storage means in the measurement server 1, and includes a transmission instruction list table 141 and a hold instruction list table 142. In addition, a plurality of clients 3
The regulation means to regulate the simultaneous transmission of measurement data from
It is realized by the measurement data transmission instruction unit 13 and the measurement data transmission instruction management table 14.

Next, the operation of the response time measuring system for the Web service will be described with reference to the flowcharts of FIGS. The Web browser 31 installed in the client 3 requests the Web server 2 to transmit the content corresponding to the URL indicated by the link information, for example, when the user selects and operates the link information. That is, the request is transmitted (steps S100 and S101).

When the response measuring unit 32 in the client 3 detects that the Web browser 31 has transmitted a request to the Web server 2, the response measuring unit 32 starts measuring the response time (step S102). For example, a response time measuring timer is started. In addition, W of the Web server 2
Upon receiving the request transmission (step S110), the eb server processing unit 21 searches the content database 22 for the requested content (step S11).
1) Input the retrieved content from the content database 22.

Furthermore, the Web server processing unit 21
The measurement server 1 is accessed via N, and the measurement data transmission instruction unit 13 of the measurement server 1 is requested to execute the measurement data transmission instruction determination process. The measurement data transmission instruction unit 13 executes the measurement data transmission instruction determination process in response to the request, and returns the execution result to the Web server 2 (steps S112 and S114). The measurement data transmission instruction determination process is a process of determining whether or not to permit the transmission of the response time measurement result (measurement data) in the client 3, and the execution result is the allowable number of transmissions of the measurement data.

The measurement data transmission instruction determination processing will be described with reference to the flowchart of FIG. The measurement data transmission instruction determination process is a process of determining whether or not the client 3 is allowed to transmit the measurement data. Is a process that regulates the number of measurement data items transmitted at the same time in a situation where is expected to be transmitted. Note that “transmitted at the same time” means that the measurement data reception processing periods in the measurement server 1 overlap.

In the measurement data transmission instruction determination process, the measurement data transmission instruction unit 13 of the measurement server 1 determines from the Web server 2 the identifier of the client 3 who has accessed the Web server 2 and requested the content, as shown in FIG. It is acquired (step S201). Next, the total sum of the numbers of transmission data items registered in the transmission instruction list table 141 is calculated (step S202). In the transmission instruction list table 141, the identifiers of the clients 3 that are permitted to transmit the measurement data and the measurement data transmission permission number (transmission data) indicating how many measurement data each of these clients 3 may transmit. The number) is registered.

When the total sum of the transmission data numbers corresponding to the total allowable number of transmissions of the measurement data is smaller than the predetermined maximum simultaneous transmission number, the measurement data transmission instructing unit 13 stores the transmission instruction list table 141 in the transmission instruction list table 141. The identifier of the client 3 acquired from the Web server 2 is registered, and "1" is registered as the number of pieces of transmission data corresponding to the client (steps S203 and S208).

In FIG. 6, when the maximum number of simultaneous transmissions is "3" and the client 3b accesses the Web server 2, the client 3b is displayed in the transmission instruction list table 141.
The situation where the identifier of a and the number of transmission data "1" are registered is shown. In that case, the measurement data transmission instruction unit 13 registers the identifier of the client 3b acquired from the Web server 2 in the transmission instruction list table 141, and also registers “1” as the number of transmission data corresponding to the client 3b.

When the measurement data transmission instruction section 13 registers the identifier of the new client 3 in the transmission instruction list table 141, whether the client identifier exists in the suspension instruction list table 142. It is confirmed whether or not (step S209). If it exists, the transmission instruction list table 14 for the client 3
The number of transmission data registered in the suspension instruction list table 142 is added to the number of transmission data 1 (step S2
10) Delete the identifier of the client 3 and the number of transmission data in the hold instruction list table 142 (step S211). That is, the entry of the client 3 is deleted from the hold instruction list table 142.

For other plural clients 3,
When the transmission of the measurement data up to the maximum number of simultaneous transmissions is permitted in total, a certain client 3 determines that the Web server 2
When is accessed, the permission to send the measurement data to the client 3 is suspended, and the number of suspensions is registered in the suspension instruction list table 142. That is, in the hold instruction list table 142, the number of occurrences (holding number) of the situation in which the client 3 cannot access the measurement data despite the client 3 accessing the Web server 2 is registered. In other words, the number of unacceptable measurement data transmission opportunities is registered in the client 3.

As will be described later, the transmission instruction list table 1
The number of pieces of transmission data registered in 41 is transmitted to the client 3 as the permitted number of transmissions of measurement data to the client 3. By the processing of steps S209 to S211, when a client 3 accesses the Web server 2, if transmission of measurement data can be permitted for that client 3, that is, transmission in the transmission instruction list table 141 at that time point. If the total number of data items does not reach the maximum simultaneous transmission number, the number of transmission data items registered in the suspension instruction list table 142 (the permitted number of transmissions of measurement data) is also included in the client 3. It is transmitted as the number of permitted transmissions of measurement data.

FIG. 7 shows that the total number of pieces of transmission data in the transmission instruction list table 141 has not reached the maximum simultaneous transmission number, the client 3c newly accesses the Web server 2, and the identifier of the client 3c is the suspension instruction list table. An example in the case of existing in 142 is shown. In that case, the measurement data transmission instruction unit 13 registers the identifier of the client 3c in the transmission instruction list table 141, and transmits the number of pieces of transmission data registered in the hold instruction list table 142 in the transmission instruction list table 141. Add to the number of data. Further, in the hold instruction list table 142, the identifier of the client 3c and the number of transmission data items are deleted.

Then, the measurement data transmission instructing section 13 determines the number of transmission data in the transmission instruction list table 141 by
The measurement data transmission instruction determination processing is returned to the Web server 2 as an execution result (step S212).

In step S203, the measurement data transmission instructing unit 13 confirms that the total number of transmission data is equal to or more than the predetermined maximum simultaneous transmission number, and then the client 3 corresponding to the identifier acquired in step S201. It is confirmed whether or not this identifier exists in the hold instruction list table 142 (step S204). If it exists, the number of transmission data corresponding to the client 3 is incremented by 1 (step S205). If it does not exist, in the hold instruction list table 142,
After registering the identifier of the client 3 (step S
206), and the number of transmission data corresponding to the client 3 is incremented by 1 (step S205). After that, as the execution result of the measurement data transmission instruction determination processing, the transmission data number “0” is returned to the Web server 2 (step S20).
7).

As will be described later, when the Web server 2 receives the transmission number data from the measurement server 1, the Web server 2 transmits the transmission number data to the client 3 together with the content. Therefore, when one client 3 desires to provide the content, the measurement data transmission instructing unit 13 sets the total number of measurement data transmissions already permitted to other clients 3 to a predetermined value. When it has not reached, it means that the control for permitting the one client 3 to transmit the measurement data is performed.

In FIG. 8, the client 3f accesses the Web server 2, and at that time, the total number of pieces of transmission data in the transmission instruction list table 141 has reached the maximum number of simultaneous transmissions, and the identifier of the client 3f indicates a suspension instruction. An example of the case where the list table 142 exists is shown. In that case, the measurement data transmission instruction unit 13 registers the identifier of the client 3f in the transmission instruction list table 141 and adds 1 to the transmission data number in the hold instruction list table 142.

Web server processing unit 21 of Web server 2
When the execution result of the measurement data transmission instruction determination process, that is, the transmission number data is received from the measurement server 1, the transmission number data is embedded in a predetermined location in the content as information indicating the allowable number (measurement data transmission instruction information) (step S112). In addition, the predetermined location is a location that is predetermined as a location to be referred to by the measurement data transmission control unit 33 in the client 3. Then We
The b server processing unit 21 transmits the content to the client 3 (step S113).

Upon receiving the content from the Web server 2, the client 3 displays the content on the content (if the content is an image: step S103). When the response measurement unit 32 in the client 3 detects that the Web browser 31 has completed displaying the content, the response measurement unit 32 ends the measurement of the response time (step S10).
4). For example, the response time measuring timer is stopped. Then, the measurement data indicating the measured response time is stored in the storage means in the client 3. A plurality of areas are secured in the storage means as areas for storing the measurement data. Then, when the measurement data is already stored in the storage means, the measurement data is stored in the next area.

Then, the measurement data transmission control unit 33 in the client 3 confirms the information indicating the allowable number embedded in the predetermined portion of the content (step S1).
05). When the information indicating the allowable number is 0, the transmission of the measurement data indicating the measured response time is suspended (step S106). If the information indicating the allowable number is not 0, all the measurement data stored in the storage unit is transmitted to the measurement server 1.

If there is measurement data for which transmission has been suspended in addition to the measurement data obtained by the process of step S104 by the client 3, the Web server 2 permits the number of suspended measurement data + 1. The number should be transmitted (see steps S208, S210, S212).
Therefore, the permissible number (the number of measurement data instructed to be sent) is set to 1
While subtracting (step S108), the measurement data stored in the storage means is sequentially transmitted to the measurement server 1 until the value of the number of measurement data becomes 0 (step S109) (step S107). It is possible to send the measurement data obtained in step 1 and the held measurement data to the measurement server 1. Here, the measurement data transmission control unit 33 transmits, for example, the latest measurement data in order. If a dial-up line or the like exists in the communication network between the client 3 and the measurement server 1, the line connection can be maintained until the processes of steps S100 to S109 are completed.

As described above, the client 3 suspends the transmission of the measurement data when the information capable of specifying the measurement data transmission allowable number indicates the measurement data transmission allowable number 0, and the measurement data transmission allowable number is set. In the case where the information that can specify “1” indicates the allowable number of transmissions of the measurement data of 2 or more, the suspended measurement data is also transmitted to the measurement server 1.

When the measurement data collection unit 11 of the measurement server 1 receives the measurement data (step S115),
Measurement data collection database 1 for received measurement data
2 (step S116). Further, the fact that the measurement data has been received and the information indicating the transmission source of the measurement data are output to the measurement data transmission instruction unit 13. The measurement data transmission instruction unit 13 updates the measurement data transmission instruction management table 14 based on the information output by the measurement data collection unit 11 (step S117).

Specifically, the measurement data transmission instruction unit 13
When the information indicating the transmission source of the measurement data is output from the measurement data collection unit 11, the client 3 that has transmitted the measurement data based on the information, as shown in FIG.
Is acquired (step S301), and the transmission data number of the corresponding client 3 in the transmission instruction list table 141 in the measurement data transmission instruction management table 14 is decremented by 1 (step S302). Then, when the number of transmission data becomes “0”, the identifier of the client 3 is deleted from the transmission instruction list table 141 (steps S303 and S304). That is, the entry of the client 3 is deleted.

As described above, in this embodiment, the measurement server 1 permits each client 3 capable of transmitting measurement data to transmit the measurement data up to the maximum number of simultaneous transmissions at the same time. Then, in a situation where the allowable number of transmissions of measurement data has reached the maximum number of simultaneous transmissions, the client 3 (We) that may newly transmit measurement data
b When a client 3) who requests content from the server 2 occurs, the client 3 is notified of the number 0 of transmission data, and transmission of measurement data is suspended for the client 3, and the suspension number is stored in the suspension instruction list table. It manages by 142 (step S204, S2
05, S206). Also, in a situation where the allowable number of transmissions of measurement data has reached the maximum number of simultaneous transmissions, even when the client 3 already notified of the suspension of transmission of measurement data requests content from the Web server 2,
Transmission of the measurement data is suspended for the client 3 by notifying the client 3 of the transmission data number 0, and the suspension number is stored in the suspension instruction list table 142.
Management (see steps S204 and S206).

Then, when the client 3 notified of the suspension of the transmission of the measurement data requests the Web server 2 for the content after the allowable number of the transmission of the measurement data does not reach the maximum simultaneous transmission number. , The suspension is released, and the transmission of the measurement data based on the access of the Web server 2 at that time and the measurement data for which the transmission is suspended is permitted (steps S203, S208, S209, S2).
10). Therefore, the client 3 is
The measurement data based on the access of the Web server 2 at that time and the measurement data whose transmission has been suspended are transmitted to the measurement server 1.

By such control, as shown in FIG. 9 (A), when the number of simultaneous accesses to the Web server 2 increases conventionally, the number of simultaneous transmissions of the measurement data 1 also increases. In contrast to the increase in traffic, in this embodiment, as shown in FIG. 9B, even if the number of simultaneous accesses to the Web server 2 increases, the number of simultaneous transmissions of measurement data is kept low. To be

In this embodiment, when the number of holds for a certain client 3 increases, the allowable number of transmissions of measurement data may temporarily exceed the maximum number of simultaneous transmissions when the hold is released. Possible (see FIG. 7). However, in general, one client 3
Measurement server 1 rather than the time interval for requesting content to
Since the time required for the measurement data reception process of 1 is short, the number of reservations for a certain client 3 does not increase so much. As a result, even if the allowable number of transmissions of measurement data exceeds the maximum number of simultaneous transmissions, the number of transmissions is not so high. Therefore, the number of transmissions of measurement data at the same time does not increase so much.

Further, in this embodiment, the hold is released on condition that a certain client 3 accesses the Web server 2, and the transmission of the measurement data whose transmission has been held becomes possible. Therefore, when the client 3 notified of the suspension of the transmission of the measurement data does not subsequently request the content from the Web server 2, the suspension state is not released. In that case, when the predetermined time has elapsed after the hold occurred, the entry of the client 3 may be deleted from the hold instruction list table 142.

In the above embodiment, the system shown in FIG. 1 is illustrated as the web service response time measuring system, but the web service response time measuring system according to the present invention is shown in FIG. It is not limited to the configuration. For example, the client 3 may access the Internet 6 without going through the routers 5a and 5b,
Any configuration may be used as long as the client 3 can request the content from the Web server 2 and can transmit the measurement data to the measurement server 1. Further, the measurement server 1 may not be directly accessible by the client 3 via the Internet 6, and may be configured to transmit the measurement data to the measurement server 1 via the Web server 2, for example. Furthermore, the Web server 2 and the measurement server 1 may be constructed by one server.

Further, although one Web server 2 is shown in the system shown in FIG. 1, there may be a plurality of Web servers 2 in the system.

[0056]

As described above, according to the present invention, the Web
Service response time measurement system and measurement server
Since the measurement server is provided with the regulation means for regulating the simultaneous transmission of the measurement data from a plurality of user terminals, the response time is measured even if a large number of user terminals simultaneously access the Web. It is possible to prevent an increase in the communication traffic of the device and an increase in the load on the measurement server.
