The present invention relates to a software streaming service model. In particular, by separating the software to be provided as a streaming service for each module, the CDN (Contents Delivery Network) based S / Ｗ streaming service that provides various levels of software desired by the user in a streaming manner. System and method. The modules may be chunks of varying levels, such as individual products of a product in which one software constitutes a unit or family of functions separated by function.

On-demand software streaming technology is a technology that executes an application image on a server through a streaming technique on the client. The client needs to download the application to its storage device or execute the application. Only parts can be sent from the server via the network and run without installation. Foreign companies that hold patents and technologies related to on-demand S / W streaming or have released their products include AppStream, Softricity, and Stream Theory. On the other hand, SoftOnNet is the only domestic company.

However, such on-demand S / W streaming service converts one software into one streaming package file and is provided to all users equally. If all users use all the features of the software, this approach should not be a problem, but given the fact that each user uses the software differently and uses only a part of it instead of the whole, it cannot be charged properly.

In addition, we cannot provide infrastructure such as network speed problem and billing problem for nationwide S / W streaming service. There is no national service.

Separately, CDN technology is a content distribution technology for regional distributed services through caching and mirroring, which is a method of resolving the centralized server and reducing network traffic. . However, this technology is still applied only to services for media data such as images, video, HTML, and the like.

The present invention has been proposed to solve the above problems, and to provide a CDN-based S / W streaming service system and method having the following object.

■ Provide differentiated software streaming services by user level.

■ Offer software at various price points.

■ Provides differentiated software streaming service by user authority.

■ CDN technology provides wide area software streaming service based on local software streaming server.

■ Allows copyright holders and copyright owners to add legitimate licenses to varying levels of differentiated software provided in a streaming fashion.

The present invention for achieving the above object is a CDN-based S / streaming service system that the global server transmits the software content to the local server using the CDN technology to provide a software streaming service to the client, the global server to itself A content distribution module for distributing the stored streaming software package to the local server; The local server may further include a S / W package receiving daemon for receiving the streaming software package distributed from the content distribution module of the global server.

The streaming software package is produced by separating one piece of software into modules and combining the separated modules into various combinations, and are given a separate license.

Upon distribution and reception of the streaming software package, license information for each streaming software package used for charging in the local server is transmitted together.

In addition, the present invention comprises the steps of separating the software into several modules to generate a software package file for a streaming service of various levels; Granting a license for each of the generated software package files; Distributing the generated software package file and license information from a global server to a local server using CDN technology; A client accessing the local server and performing an authentication process to receive a streaming service; And after the authentication process, the client provides a CDN-based S / Ｗ streaming service method comprising the step of receiving a software streaming service.

While the client is receiving the software streaming service, the local server further includes the step of recording log data, calculating billing based on the log data, and recording the calculation result as billing data, wherein the log data is user Include ID, name of the software used, license type, and usage time.

The following is a detailed description with reference to the accompanying drawings for a CDN-based S / W streaming service method according to the present invention.

1 is a schematic diagram of a CDN based streaming system according to the present invention. The global server 110 transmits the software content to the local server 120 using CDN technology to provide a software streaming service to the client 130. The client 130 receives the desired software from the local server 120.

FIG. 2 is a schematic diagram of creating a differential streaming software package 230 by separating one piece of software into modules. First, the software 210 is separated into modules 220. The separated modules 220 are bundled into various combinations to produce streaming software packages 230, 231, and 232.

3 is a schematic diagram of distributing the streaming software package 352 and the licensing information 330 for each streaming software package to the local server 310 by using CDN technology, and is differentiated software stored in the global server 350. The packages 352 and the license information 330 are distributed using the content distribution module 351 of the global server 350 and the S / W package receiving daemon 311 of the local server 310. The storage device 312 of the local server 310 also stores license information 330 together with the streaming software package 313. License information 330 is used by each regional server 310 for billing.

4 is a flowchart illustrating the overall flow of a streaming service embodiment according to the present invention. The client 130 goes through the authentication process 402 to access the local server 310 to receive the streaming service. If you do not register as a member asks whether you want to join (403), if you want to join the membership registration process (405) is performed. If you do not want to join the service is terminated (409). The client 130 that has successfully completed the membership registration process 405 or the authentication process 402 checks whether the S / W package 313 of the desired level exists in the local server 310 (404). If not, it is asked whether to terminate the service (408). If the S / W package 313 of the desired level is present in the local server 310, data is requested from the local server 310 (406). The client 130 receives the requested data and records 408 log data at the local server 310. The client 130 may terminate the service 409 at a desired time while using the S / W as the received data.

FIG. 5 is a flowchart illustrating a process of recording charging data by the local server 310 when the client 130 uses the CDN-based S / W streaming service. When the local server 310 receives the S / W streaming service request from the client 130 (502), the local server 310 starts to record the log data (503). When the client 130 stops using the software or disconnects the client 130 from the local server 310 (504), the local server 310 uses the S / W name, license type, and usage time in the log data. Based on the calculation of the fee (505). After the calculation, the local server 310 stores the result with the user ID in the DB (506) and terminates the charging module (507).

According to the present invention, the software is configured and billed according to the various needs of the user so that service providers and users can provide and use the service legitimately, and copyright holders and neighboring rights holders have an effect of receiving a royalty fee appropriate for the streaming service. .

In addition, the present invention can be divided into a single software, for example, basic functions, advanced functions, special functions, etc. to provide and use various levels of software for the user, or to use only some of the software of the product family composed of several products Various service product composition and the fee for use can be determined.

In addition, the present invention has the effect of promoting a wide area software streaming service based on a local software streaming server software streaming service that was made only in a narrow range, such as a company, school, institution, organization.
