Hereinafter, a method and a server apparatus for measuring quality of a web service according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of a web service measurement system 100 according to an embodiment of the present invention.

Referring to FIG. 1, the web service measurement system 100 illustrates a client 110 and a server device 120.

A plurality of clients 110a, 110b, 110c,... 110n (hereinafter collectively 110) are each capable of communicating with the server device 120 via a network (eg, the Internet 130). The client may be, for example, a personal computer (PC), PDA, smart phone, other communicable device.

The server device 120 may provide a web service, often referred to as a web server. For example, upon receiving the web page request from the client, the server device 120 provides the web page to the client in response. In this regard, in FIG. 1, the server device 120 is shown as including a receiving module 121, a transmitting module 122, an HTML generating module 123, an analyzing module 124, and a collecting module 125. It is obvious that other configurations related to the provision of web services may be included.

When there is a web page request from the client, the transmitting module 122 transmits web page related data to the client according to the request. In this regard, the server device 120 may receive a web page request from the client through the receiving module 121, and the receiving module 121 will be described in more detail later.

In one embodiment, the web page related data may include main HTML, a flash component, and the like, and may include visual information such as a timestamp, and the sending module 122 may include a main HTML, a flash component, or the like. Web page related data can be sent to the client sequentially.

The HTML generation module 123 generates main HTML including visual information (eg, time stamp) therein. In this regard, the time information indicates a time for generating the main HTML, and the HTML generation module 123 may generate the main HTML by including the time information therein, for example, in a script format. On the other hand, the main HTML returns the visual information (and client-related information such as operating system (OS), web browser information, etc.) at the time when the processing (eg, loading and rendering) of the web page related data is completed in the client 110. Instructions may be included to cause the message to be sent to the server device 120, which may be, for example, in the form of a script.

The receiving module 121 may receive a return message from the client 110, and the return message is transmitted to the server device 120 upon completion of processing of web page related data at the client, and includes time information. Meanwhile, as described above, the reception module 121 may receive a web page request from a client, and the HTTP protocol scheme may be applied to the series of processes.

The analysis module 124 may measure the quality of experience of the corresponding web service of the client using the received return message. In one embodiment, the analysis module 124 may derive the web page processing time by using the time information included in the return message and the time when the return message is received, which will be further described below with reference to FIG. 2. Explain in detail.

In another embodiment, the client 110 may obtain time information from the server device 120 to calculate the time required to provide a web page through a web browser, and the web page providing time information calculated as described above may be returned. It may be included in and delivered to the server device 120. In this case, the analysis module 124 may use the calculated time information included in the return message as a web service provision quality index.

In one example of the invention, server device 120 may include a collection module 125, which collects return messages received from each of a plurality of clients 110.

Meanwhile, in another embodiment of the present invention, the return message from the client 110 may be transmitted to a collection server (not shown) configured separately from the web server providing the web page. In this case, the collection server includes the functions of the reception module 121 and the collection module 125 of the web server, and collects, generates, and manages the indicators for the service quality evaluation of the web server. It may be referred to as a server device 120. This configuration will be described in detail with reference to the other drawings.

2 is a diagram illustrating a flow of data according to an embodiment of the present invention.

Referring to FIG. 2, a flow of data between a server device and a client is shown, and the client may communicate with the server device using a web browser (eg, Internet Explorer, Safari, etc.). have. In addition, A to I indicate a specific time point will be described in detail below.

At point A, the client sends a web page request (eg, a URL request) to the server device. Subsequently, at time B, the server device receives the web page request.

Subsequently, at point C, the server device generates the main HTML, and includes the time information indicating the point C in the main HTML, and the main HTML includes a return message including the time information when the web page related data is processed by the client. Instructions for causing a to be received from the client.

In the above description, the C point of time indicates the start of preparation work of the server device corresponding to the web page request, and may be described as a start time of generating the main HTML for providing the web page. Since the preparatory work corresponding to the web page provision request is immediately started in response to a request from the client, the point C can be understood as the point in time corresponding to the reception of the web page provision request.

Then at point D, the server device sends the main HTML to the client. Then at point E the client receives the main HTML sent. On the other hand, the server device transmits the last component for providing the web page requested at the time point D and after the point D, and the client receives the last component at the time G after the point E. That is, the G point can be understood as the completion point of the web page loading on the client.

On the other hand, the client renders the received data after the E time point, and the rendering is completed at the H time point. That is, time H can be understood as the completion point of the web page rendering in the client, and time H can be understood as the completion point of the web page providing process for the client user.

In one embodiment of the present invention, the client transmits a return message containing time information to the server device at the time G when the web page loading is completed, and then the server device receives the return message at time I. In another embodiment of the present invention, the client transmits a return message including visual information to the server device at the time H when the web page rendering is completed. In one embodiment, the return message may include not only visual information but also information on an operating system (OS) of a client, a web browser, and the like.

The server device may measure the web service quality of experience of the client using the received return message. If the server device can measure the time from when the client requests the web page to the actual view of the web page, this can provide an important criterion for measuring the quality of the web service experience.

That is, in relation to FIG. 2, the time between the time point A when the client requests the web page and the time point H when the rendering of the web page is completed may be a criterion for measuring the quality of the web service experience of the client. The time until can be referred to as 'web page processing time' from the client's point of view.

In order to obtain the result of accurately measuring the 'web page processing time', the server device may require a separate agent program installed on the client, which operates as a major limitation of the prior art.

On the other hand, the present invention is characterized in that the web page processing time can be indirectly measured without installing a separate agent program on the client, for this purpose, we propose the following improved method.

The server apparatus receives the web page request sent at time A at time B, and then generates main HTML including time information corresponding to time C at time C. Thereafter, the server apparatus receives a return message including the time information at time I. Accordingly, the server apparatus may derive the time between the time when the main HTML is generated (view point C in FIG. 2) and the time when the return message is received (view point I in FIG. 2) using the received return message. In this regard, an equation relating to a web page processing time, that is, a time between A and H can be calculated as follows.

T _HA = T _BA + T _IB -T _IH = T _BA + T _IC + T _CB -T _IH

Here, T _HA is the time between time A and H, T _BA is the time between time A and B, T _IB is the time between time B and I, and T _IH is between time H and I It's time. Of the T _BA, T _IC, T _CB, T _IH items related to the T _HA, items having a relatively long period of time under normal conditions is a T _IC directly related to the loading and rendering of the web page related data, compared with T _IC Therefore, the remaining T _BA , T _CB , T _IH etc. are small enough to be ignored. Accordingly, the T _HA is substantially the same as the T _IC, and the time from the time point A to the time point H, that is, the time from the time point C to the time point I to obtain the web page processing time, unless it requires a few milliseconds of precision. It is possible to obtain a sufficiently satisfactory result only by obtaining, and the time from the time point C to the time point I can be derived using the return message as described above.

In other words, the T _CB is small enough to be ignored (in this sense, the point C can be understood as the point of time corresponding to the receipt of a web page presentation request) and the T _BA and T _IH perform substantially similar operations. Under the premise of having the same value, the time from time A to time H, that is, the web page processing time may be approximated to the time between time C and time I. Accordingly, in one embodiment of the present invention, the web page processing time in the client is indirectly based on the time information corresponding to the completion of the reception of the request for providing the web page and the time information corresponding to the completion of the reception of the return message according to the completion of the rendering of the web page. It can be measured by

This indirect measurement method may be performed based on visual information corresponding to completion of reception of a web page provision request and visual information corresponding to completion of reception of a return message upon completion of web page loading (complete transmission of a component of a requested web page). Can be.

In some cases, the reference time point of time measurement as an indicator for measuring web page provision quality may be changed. For example, the time between point E and point G can be used as such an indicator, which can be used as a performance indicator for the time spent by a web browser on the client.

In addition, the return message may include not only visual information but also information on the OS, web browser, etc. of the client, so that the server device goes beyond a simple collection of web page processing time of each client, and thus the type of OS. The processing time of the web page and the processing time of the web page according to the type of the web browser can be known, which can enable the server device to more accurately measure the web service experience quality of the clients.

That is, in addition to the time indicators for some or all of the web page processing process, other indicators that may be characteristic of the client may be included together in the return message, or may be obtained through other paths. It can be used for more specific web service quality measurement.

3 is a diagram illustrating a flow of data according to another embodiment of the present invention. Meanwhile, since the server device of FIG. 2 includes the web server and the collection server of FIG. 3, the server device of FIG. 2 will be described below with reference to FIG. 3 with reference to FIG. 3 to avoid overlapping descriptions.

In FIG. 3, a web server and a separate collection server that can be distinguished from each other are illustrated, and perform a function equivalent to that of the collection module 125 of the server device of FIG. 2. Meanwhile, although a separate web server and a collection server are illustrated in FIG. 3 so as to be distinguished from each other, a server device including the functions of the web server and the collection server in various ways according to the technical level of the related art and the technical common knowledge of those skilled in the art. It can be appreciated that it can be implemented. Meanwhile, when there is a web server and a separate collection server that can be distinguished from each other as shown in FIG. 3, the web server may use the same time server for time synchronization with the collection server or periodically perform time synchronization. Can be.

The collection server collects the return message received from each client. Accordingly, the future collection server may be used to calculate the web service haptic quality for a predetermined period.

In one embodiment of the present invention, time information at various points that may be utilized for web service performance measurement may be included in the return message and transmitted. When this information is delivered in a single return message at a time, the server device or collection server receiving the return message can derive an indicator for the web page serving from the return message alone, without having to look at other logs for the client. It has the advantage that it is.

That is, by including the time information (points B, C, E, and the like mentioned above) related to the start of web service provision in a return message corresponding to the completion of the web service provision, the web page is provided. It is advantageous in that it is possible to calculate various service quality evaluation indices for the provided web page based on the received return message without complicated analysis of the log.

Referring to FIG. 4, in step 410, the server device receives a web page request from a client.

Thereafter, in step 420, the server device sequentially sends web page related data, such as main HTML, and related components to the client. In addition, although not shown in FIG. 4, step 420 may include generating main HTML including visual information. As described above, main HTML may include processing (eg, loading) web page related data. And the visual information (which may include visual information of various viewpoints such as viewpoints B, C, and E of FIGS. 2 to 3) and additionally client-related information such as operating system (OS) and web browser information at the completion of rendering). It may also include a command to cause the return message to be sent to the server device.

Thereafter, in step 430, the server device indicates the completion of the processing of the web page related data, and receives a return message from the client that includes the time information or also includes the client related information.

Subsequently, in step 440, the server device may derive the haptic quality information of the web page by using the received return message, which has been described above with reference to FIGS. 2 and 3.
