Description

TECHNICAL FIELD [0001] The present invention relates to a server testing method for a cloud streaming service,

The present invention relates to a test system for a server, and more particularly, to a server testing method for a cloud streaming service capable of stabilizing a service by checking a server that provides data in a cloud system in advance and checking for a failure, And more particularly, to a system and an apparatus.

A cloud system is an Internet-based computer technology, in which the cloud is a complex infrastructure hidden on a computer network, the Internet. Cloud computing is an environment in which users can use the Internet at any time and easily share data with various information and communication devices without installing the necessary software on their computers. In other words, an individual can access the Web and work on programs such as Photoshop and Office, and the work is stored on the Web. Ultimately, you can have only one server (computer) in the virtual space, and that many people can do their jobs through these computers. APM of bank, real-time seat reservation system of aircraft and train is representative.

As the IT technology develops, the application market grows, and the SNS market becomes more active, the amount of data such as user content is surging. And now, the data becomes supersaturated, and it becomes a situation that it is difficult to deal with each terminal. This situation can be completely solved by the cloud system. And this cloud system will be the foundation for building a tiny device environment. For example, in executing a service or a function requiring a large amount of image processing, the service or function may be executed through a server based on cloud computing, and only the executed result screen may be transmitted to the user's terminal So that the user can utilize services or functions requiring high-performance or high functionality through the terminal. A technology that enables a user terminal to use various services or functions through a screen virtualization technology that executes a specific service or function according to a request of the user terminal and transmits the result to the user terminal is called a cloud streaming service.

In particular, the service provision technology based on cloud streaming is intended to constitute a large-scale cloud node and to execute a computer game performed in a game console (Consol) or a high-performance PC on each cloud node, And the user input generated in the user terminal can be immediately received by the cloud node and reflected in the game.

This cloud-streaming technology enables high-quality 3D applications on mobile handsets and digital TVs without the need for additional equipment. In addition, since the 3D application is not installed in the terminal or the update is not executed, it can be used immediately. In addition, the development cost can be reduced because a single platform can be developed and serviced on a plurality of platforms. In addition, since the usage pattern of the user can be stored in the server, it can be analyzed and applied to the implementation of better game play, and the execution error of the application can be stored in the server and used for error correction. In addition, patches and upgrades are easy because game patches and upgrades are made on servers in the data center. In addition, there is no risk of piracy because the game code does not leak out of the data center where the server is located.

However, the requirements for providing such a cloud streaming-based service include high responsiveness, high image quality, and quality of the image as well as the quality of the image and the service system can be driven at a low cost You need technology. In addition, it is required to develop a technology to detect whether the server operation is obstructed in advance and to maintain the stability of the service.

It should be interpreted as meaning and concept consistent with the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It is to be understood that equivalents and modifications are possible.

In the present invention, description will be made of a technique for testing a server so as to stabilize a service in a cloud system. In particular, the present invention compares data received from each server at the request of a test apparatus, and performs a test to check whether the operation of the server, such as performance and function, has failed.

First, a test system of a server for a cloud service for testing a server according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of a test system of a server for a cloud streaming service according to an embodiment of the present invention.

Referring to FIG. 1, a test system of a server for a cloud streaming service includes a plurality of clients 100, 101, and 102 connected through a communication network 110, (120) and a plurality of servers (130, 140, 150). In the embodiment of the present invention, three clients are assumed and three virtual client modules included in the test apparatus 120 are described.

A plurality of clients 100, 101 and 102 is a terminal capable of transmitting and receiving various data via the communication network 110 and includes a tablet PC, a laptop, a personal computer (PC) A smart phone, a personal digital assistant (PDA), a smart TV, a mobile communication terminal, and a set-top box.

The clients 100, 101, and 102 may also include a browser for communicating with the servers 130, 140, and 150 via the communication network 110, a memory for storing programs and protocols, A microprocessor, and the like. That is, the clients 100, 101, and 102 may be any terminal as long as they can communicate with the servers 130, 140, and 150 and may be a broad concept including a communication computer such as a notebook computer, a mobile communication terminal, to be.

The communication network 110 refers to a network capable of transmitting and receiving data using an Internet protocol using various wired and wireless communication technologies such as an Internet network, an intranet network, a mobile communication network, and a satellite communication network. The communication network 110 may be a closed network such as a LAN (Local Area Network) or a WAN (Wide Area Network), an open network such as the Internet, a CDMA (Code Division Multiple Access), a WCDMA The concept is called the next generation network and computing network that will be implemented next, such as Multiple Access, Global System for Mobile Communications (GSM), Long Term Evolution (LTE) and Evolved Packet Core (EPC) Meanwhile, the communication network 110 is not limited to the above-described communication method, and may include any other known or later-developed communication methods in addition to the communication methods described above.

The test apparatus 120 is a server for testing the servers 130, 140 and 150. The test apparatus 120 includes a virtual client module in the test apparatus 120 that performs the same operations as the clients 100, 101, and 102. At this time, the number of virtual client modules is equal to the number of actual clients.

When the test data transmitted from each of the servers 130, 140 and 150 is received by each of the virtual client modules, the test apparatus 120 compares the synchronization information of the received test data with preset reference synchronization information, Or whether it is within the predetermined error range. For example, if it is determined that the synchronization information of the test data received from the server 130 is out of the predetermined error range, the server 130 determines that the server is a failed server.

Here, the comparison of the sync information is to compare information such as data amount and data latency with each other. Although the sync information of the test data may be 100% coincident with the reference sync information, if the error amount of the sync information falls within a preset error range, it can be determined that there is no failure of the server.

As described above, in the present invention, the virtual client modules each receive test data from different servers. At least one of the virtual client modules receives test data from different servers, and the sink data of the test data received from the virtual client module With the reference sync information, and determines whether the corresponding server has failed according to the comparison result.

In addition, the test apparatus 120 according to another embodiment of the present invention requests each of the servers 130, 140, and 150 to transmit test data for testing. At this time, the test apparatus 120 can request the respective servers 130, 140 and 150 to transmit test data at the same time. Each server 130, 140, 150 transmits test data to the test apparatus 120 at the requested time according to the request of the test apparatus 120. [ Then, the test apparatus 120 confirms the reception time of the test data received for each server. For example, the test apparatus 120 may receive the test data from the server 130 at a time t1 when the test data is first received from the server 130, at the time t2 when the test data is first received from the server 140, The first received time t3 is checked, and the time at which the test data is received for each server is compared. That is, the test apparatus 120 assumes that the time t1 at which the test data is received from the server 130 and the time t2 at which the test data is received from the server 140 are received within the predetermined error range at the same time When the time t3 when the test data is received from the server 150 and the times t1 and t2 when the test data is received from the servers 130 and 140 are in different ranges, It can be determined that a failure has occurred in the server 150.

On the other hand, the test apparatus 20 can repeatedly receive the test data repeatedly at predetermined intervals for more reliable testing.

When the number of virtual client modules included in the test apparatus 120 is smaller than the number of the servers 130, 140, and 150 and each of the virtual client modules does not correspond to each other on a one-to-one basis, , And executes the test so that the aggregated servers correspond to the virtual client modules.

The virtual client modules 250, 252, and 254 transmit the received test data to the comparison unit 220 according to the reception test data delivery request of the comparison unit 220. [ The internal configuration of the virtual client modules 250, 252, and 254 may be as shown in FIG. Since the configuration of each virtual client module 250, 252, 254 is the same, the internal configuration of the virtual client module 250 will be described in the description of FIG.

That is, the server 130 transmits the test data to the virtual client module 250, the server 140 transmits the test data to the virtual client module 252, and the server 150 transmits the test data to the virtual client module 254 Test data is transmitted.

The test control unit 200 of the test apparatus 120 receiving the test data requests the comparison unit 220 to compare the test data according to the test request (S408, S410).

The comparison unit 220 of the test apparatus 120 requests transfer of the test data received from the servers 130, 140 and 150 to the respective virtual client modules 250, 252 and 254 (S412, S414 and S418).

Each of the virtual client modules 250, 252, and 254 transmits the received test data to the comparison unit 220 according to the request of the comparison unit 220 (S414, S418, and S422).

After that, the comparing unit 220 compares the sync information of each received test data with preset reference synchronization information, and then transmits the comparison result to the test controller 200 (S424, S426).

If the comparison result indicates that the synchronization information matches the preset reference synchronization information or falls within the set error range, the test control unit 200 determines that the server has no failure, If the set error range is exceeded, it is determined that there is a failure in the server (S428). At this time, the comparison result is transmitted to the test control unit 200 for each of the servers 130, 140, and 150, and the test control unit 200 determines whether or not the respective servers have failed according to the comparison result.

At this time, all the virtual client modules receive test data from different servers, and the test device 120 compares the received test data.

If the comparison result indicates that the synchronization information matches the preset reference synchronization information or falls within the set error range, the server determines that there is no failure, and if the synchronization information falls outside the set error range, it determines that the server has a failure. This determination process is performed on the synchronization information of test data received in all the virtual client modules (S506 to S510).

In addition, the test control unit 200 according to another embodiment of the present invention requests each of the servers 130, 140 and 150 to transmit test data for testing. At this time, the test control unit 200 can request the respective servers 130, 140 and 150 to transmit test data at the same time. Each server 130, 140, 150 transmits test data to the test apparatus 120 at the requested time according to the request of the test apparatus 120. [ Then, the test control unit 200 checks the reception time of the test data received for each server. For example, the test control unit 200 may receive the test data from the server 130 at a time t1 when the test data is initially received from the server 130, at the time t2 when the test data is first received from the server 140, The first received time t3 is checked, and the time at which the test data is received for each server is compared. That is, the test control unit 200 assumes that the time t1 at which the test data is received from the server 130 and the time t2 at which the test data is received from the server 140 are received within the predetermined error range at the same time When the time t3 when the test data is received from the server 150 and the times t1 and t2 when the test data are received from the servers 130 and 140 are in different ranges, the servers 130 and 140 operate normally , It can be determined that a failure has occurred in the server 150.
