On the other hand, if the corresponding data is not being cached, the cloud server 200 transmits a data request to the connected proxy server 600. The proxy server 600 can receive the data provided by the service interworking system 700 providing the corresponding data and control the entire process of transmitting the data to the client device 100 in a streaming manner.

2, the cloud server 200 of the present invention is implemented as a set of a plurality of cloud servers 200, as shown in FIG. 2 . In addition, each of the cloud servers 200 includes a cloud device 20a, 20b, 20c (hereinafter, referred to as " 20 " if no separate distinction is required) as a device for providing a cloud streaming service, (30a, 30b, 30c, hereinafter, referred to as " 30 " if no further distinction is necessary), and the data stored in the cache device (30) (100).

More specifically, the cloud device 20 constituting the cloud server 10 receives a request from the client device 100, and provides a corresponding result screen to the client device 100 in a cloud streaming manner Role. At this time, the cloud device 20 requests the service interworking system 700 to execute the data via the web server 300 or the proxy server 600 according to the request of the client device 100, Capturing an execution screen of the corresponding data to generate a captured image, encoding the captured image, and transmitting the encoded data to the client device 100.

[ More specifically, when the cloud device 20 is interlocked with one cache device 30 and an execution request for specific data is received from the client device 100, The cloud device 20 executes the corresponding data to the service interworking system 700 via the web server 300 or the proxy server 600 located at a remote location, if it is cached after checking whether the data is cached in the service interworking system 30 It is possible to stream the encoded data to the client device 100 directly after encoding the cached execution picture in the cache device 30, instead of requesting the client device 100 to play the encoded data. At this time, the execution image of the specific data cached in the cache apparatus 30 may exist in the form of a captured image, and if the encoded data is cached, it may be directly transmitted to the client apparatus 100 without any encoding process.

In addition, the cloud device 20 according to an embodiment of the present invention may provide a cloud streaming service to the client device 100 through interworking with an adjacent cloud device 20 in an environment including a plurality of cloud servers 10 It is possible. 2, in an environment including a plurality of cloud servers 10, such as a first cloud server 10a, a second cloud server 10b, and a third cloud server 10c, The first cloud device 20a directly sends the corresponding specific data to the web server 300 or the service interworking system 700 when the specific data requested by the client device 100 is not cached in the first cache device 30a connected to the first The second cloud device 20b and the third cloud device 20c, which are capable of interworking with each other, can inquire whether the specific data is cached or not. At this time, it is possible to sequentially query or query at the same time with another cloud device capable of interlocking. In other words, when the first cloud device 20a receives the execution request of the specific data from the client device 100 but the corresponding data is not cached in the first cache device 30a connected to the first cloud device 20a, The first cloud device 20a first inquires whether or not the corresponding data is cached by the adjacent second cloud device 20b. Upon receiving the data, the second cloud device 20b confirms whether or not the corresponding data of the second cache device 30b connected thereto is cached. If the data is cached, the second cloud device 20b transmits the cached data to the first cloud device 20a . On the other hand, if the second cloud device 20b does not cache the second cache device 30b connected thereto, it notifies the first cloud device 20a that the first cache device 20a is not caching the first cache device 20a. The other cloud device, that is, the third cloud device 20c, queries whether the corresponding data is cached. The third cloud device 20c receives the data and checks whether the data is cached in the third cache device 30c connected to the third cloud device 20c. If the data is cached, the third caching device 20c transmits the data cached in the third cache device 20c, To the device 20a.

On the other hand, the first cloud device 20a may be subjected to the sequential inquiry process as described above, but may be performed on all the adjacent cloud devices, that is, whether the specific data is cached by the second cloud device 20b and the third cloud device 20c Can be queried simultaneously. At this time, when a response indicating that the corresponding data is being cached is received from the second cloud device 20b and the third cloud device 20c, the first cloud device 20a receives the response from the second cloud device 20b and the third cloud device 20b, And may request the device 20c to selectively transmit the corresponding data. At this time, the second cloud device 20a may select a cloud device to receive data according to the distance to each of the other cloud devices in which a response is received.

If the first cache device 20a is not caching data requested by the client device 100 to all the neighboring cloud servers 10 as well as the first cache device 30a connected to the first cache device 20a, And requests the execution of the corresponding data by the service interworking system 700 via the proxy server 600 and / or the proxy server 600 and transmits the corresponding data from the service interworking system 700 via the web server 300 and / or the proxy server 600 The first cloud device 20a captures and encodes it on a browser basis, and then transmits the encoded data to the client device 100 in a streaming manner. At this time, the first cloud device 20a may control the captured image captured by the browser unit to be cached in the first cache device 30a connected to the first cloud device 20a.

The proxy server 600 of the present invention supporting the above process is located between the cloud server 200 and the service interworking system 700 for providing data and is interworking between the cloud server 200 and the service interworking system 700 .

Hereinafter, a main configuration and an operation method of a proxy server according to an embodiment of the present invention will be described.

5 is a block diagram illustrating a main configuration of a proxy server according to an embodiment of the present invention.

1 and 5, the proxy server 600 according to the embodiment of the present invention may include a data processing module 61, a storage module 62, and a communication module 60. Here, 'module' is a component that performs a predetermined function, and may be implemented by hardware, software, or a combination of hardware and software. For example, the 'module' may refer to a program module, which may be software components executed by a processor to perform certain functions, object-oriented software components, class components, Data, databases, data structures, tables, arrays, data structures, and the like, such as, for example, , And variables. In addition, the functions provided in the components and 'modules' may be combined into a smaller number of components and '~ modules' or further separated into additional components and 'modules'.

Hereinafter, each configuration of the present invention will be described in more detail. First, the data processing module 61 refers to a module for controlling the overall operation of the proxy server 600 according to the embodiment of the present invention. The data processing module 61 can receive a request for specific data requested by the client device 100 from the connected one of the cloud servers 200 via the communication module 60 and receive the request. Then, the data processing module 61 confirms the service interworking system 700 including the corresponding data, and requests the data to the confirmed interworking system 700 to receive the data. At this time, the data processing module 61 does not transmit the data received from the service interworking system 700 to the cloud server 200 as soon as it receives the data, but first determines whether the received data is cacheable in the cloud server 200 . At this time, the data processing module 61 can determine whether caching is possible by comparing with the previously stored setting information. At this time, the types and formats of data that can be cached for each of the cloud servers 200 may be different. Accordingly, the data processing module 61 compares the previously stored configuration information corresponding to the corresponding cloud server 200, and determines whether or not it is cacheable. For example, when the data provided by the service interworking system 700 does not support the HTTP protocol while the cloud server 200 caches data based on the HTTP protocol, the data processing module 61 transmits the data It is determined that caching is impossible in the cloud server 200, and the data is converted so that the cloud server 200 can cache it.

The information to be converted may be either a cache control value included in the header information of the data, an expiration time, or a last modified time. In addition, the data processing module 61 may modify or insert any one of the cache control value, the valid period, and the latest modification time included in the header information according to the type of the data. For example, in the case of data for user interface processing, in which frequent changes are made periodically, the data processing module 61 may change the valid period to match the period. On the other hand, in the case of data that does not need to be periodically changed, the data processing module 61 can set the validity period to be short.

In addition, the data processing module 61 inserts a key required by the back office in the request when requesting data to the service interworking system 700 for data conversion processing, and transmits a data request with a key requested by the back office Service interworking system 700. Thereafter, when the data is received from the service interworking system 700, the previously inserted request key is deleted, and the header can be modified so that the cache can be performed. For example, in the case of data that does not support the HTTP protocol, the data can be converted to support the HTTP protocol.

The data processing module 61 can immediately provide the data to the cloud server 200 without any conversion processing if the data transferred from the service interworking system 700 can be cached in the cloud server 200. [

The storage module 62 is a module for storing data necessary for the operation of the proxy server 600. In particular, the storage module 62 according to the present invention stores the setting information DB 62a. At this time, the setting information DB is information to be a reference for judging whether or not it is cacheable data.

Hereinafter, a method of providing a cloud streaming service using a cache apparatus according to an embodiment of the present invention will be described.

6 is a flowchart illustrating a method of providing a cloud streaming service in a cloud server according to an embodiment of the present invention.

1 and 6, a method for providing a cloud streaming service in a cloud server according to an exemplary embodiment of the present invention is performed by a cloud server 200, and in particular, .

That is, the cloud device 10 receives a specific data execution request from the client device 100 (S101). Here, the specific data may be a web application such as a user interface application. However, the present invention is not limited to this, and may be a set of a plurality of data such as a specific content such as a moving image or an image accessible through a user interface application.

The cloud server 10 receives the specific data and determines whether or not the specific data is cached in the cache apparatus 20 that can be interlocked with the cache server 20. If the cache server 20 does not cache the specific data, The service interworking system 700 requests the execution of the data through the server 600 in operation S105 and executes the execution of the data transmitted from the service interworking system 700 via the web server 300 or the proxy server 600 (S107), encodes (S109) a result screen according to the streaming request, and provides streaming to the client apparatus 100 to provide it.

On the other hand, if the corresponding data is being cached in step S103, the cloud server 10 can directly encode the cached data and perform streaming to the client device 100 without going through steps S105 and S107. As described above, the present invention can provide a more rapid cloud streaming service to the client device 100 through interworking with the cache device 20.

The above process will be described step by step with reference to FIG.

7 is a data flow diagram for more specifically illustrating a method of providing a cloud streaming service according to an embodiment of the present invention.

Referring to FIG. 7, the client device 100 requests data execution from the plurality of cloud servers to the cloud device 20 of the cloud server 200 adjacent to the client device 100 (S201). The cloud device 20 receives the request and inquires whether the data is cached by the cache device 30 connected thereto (S203), and the cache device 30 determines whether or not the data is being cached. At this time, the cache apparatus 30 can determine using the header information of the data. If it is determined in step S205 that the cache apparatus 30 has cached the corresponding data in step S205, the cache apparatus 30 transmits the cached data to the cloud apparatus 20 in step S207. The cloud device 20a encodes the data (S209) and transmits the encoded data to the client device 100 in a streaming manner.

The client apparatus 100 that has received the streaming data can decode and play back streaming data (S213).

On the other hand, if the corresponding data is not cached in the cache device 30 connected to the cloud device 20 in step S205, the cache device 30 guides the cache device 30 to the cloud device 20, The server 600 can request data.

The above process will be described with reference to FIG.

8 is a data flow diagram for further illustrating a method of providing a cloud streaming service according to an embodiment of the present invention.

That is, to explain the operation when the cache apparatus 30 is not caching data in step S205 of FIG. 7, the cloud device 20 of the cloud server 200 transmits data to the connected proxy server 600 (S301). Then, the proxy server 600 requests data from the service interworking system 700 providing the data (S303), and receives and receives data from the service interworking system 700 (S305).

The proxy server 600 receiving the data transmits the data to the cloud device 20 of the cloud server 200 at step S307 and the cloud device 20 receiving the data transmits the data to the client device 100 , The result screen is captured (S309) and encoded (S311). The cloud device 20 transmits the encoded data to the client device 100 in a streaming manner (S313), and at the same time supports the corresponding data to be cached in the cache device 30 connected thereto (S315 to S317). Here, the cached data can be cached by capturing the result screen according to the execution, and the encoded data may be cached according to the implementation method.

In addition, when the streaming data is received from the cloud device 20 of the cloud server 200, the client device 100 can decode and reproduce the streaming data (S319).

The proxy server 600 according to the embodiment of the present invention firstly transmits data to the cloud server 200 when the data is transferred from the service interworking system 700 to the cloud device 20 at step S305, The cloud device 20 can determine whether the corresponding data is cacheable.

The above process will be described with reference to FIG.

9 is a flowchart illustrating a method of providing a cloud streaming service in a proxy server according to an embodiment of the present invention.

Referring to FIG. 9, the proxy server 600 receives a data request from the client device 100 from the cloud server 200 (S401). Here, when the proxy server 600 is connected to the plurality of cloud servers 200, the proxy server 600 may receive data requests from any one of the cloud servers 200. At this time, the request may identify the cloud server 200 Information may be included.

The proxy server 600 receiving the data confirms the service interworking system 700 providing the corresponding data. Here, a plurality of service interworking systems 700 to which the proxy server 600 is connected may exist, and the proxy server 600 may store and manage information on data held by the plurality of service interworking systems 700 .

After confirming the service interworking system 700 providing the data, the proxy server 600 can request and receive data from the service interworking system 700 (S403). The proxy server 600 does not transmit the data to the cloud device 20 of the cloud server 200 as soon as the data is received but transmits the data to the cache device 30 of the corresponding cloud server 200, It is possible to determine whether or not it is cacheable. Since the type and format of data that can be cached may be different for each of the cloud servers 200, the proxy server 600 may compare the pre- It is possible to determine whether caching is possible by comparing with the preset information corresponding to the server 200 (S405). If it is determined that the corresponding data is not cached in the cache device 30 of the cloud server 200, the proxy server 600 transforms the data to enable caching (S407).

For example, if the data provided by the service interworking system 700 does not support the HTTP protocol while the cloud server 200 caches data based on the HTTP protocol, the proxy server 600 transmits the corresponding data The cloud server 200 determines that caching is not possible, and the cloud server 200 transforms the data so that the cloud server 200 can cache the data.

The information to be converted may be either a cache control value included in the header information of the data, an expiration time, or a last modified time. In addition, the proxy server 600 may modify or insert any one of the cache control value, the valid period, and the latest modification time included in the header information according to the type of the data. For example, in the case of data for user interface processing in which periodic frequent changes are made, the proxy server 600 may change the expiration period according to the period. On the other hand, in the case of data that need not be periodically changed, the proxy server 600 can set the validity period to be short.

In addition, the proxy server 600 inserts a key requested by the back office in the request when requesting data to the service interworking system 700 for data conversion processing, and transmits the data request inserted with the key requested by the back office to the service To the interworking system 700. Thereafter, when data is received from the service interworking system 700, the previously inserted request key is deleted, and the header can be modified to enable caching. For example, in the case of data that does not support the HTTP protocol, the data can be converted to support the HTTP protocol.

After that, the proxy server 600 delivers the converted data to the cloud server 200, and the cloud device 20 of the cloud server 200 receives the converted data, and then, as described with reference to FIG. 8, The execution screen is captured and encoded, the encoded data is streamed and transmitted to the client apparatus 100, and at the same time, it is controlled to be cached in the cache apparatus 30.
