The virtual desktop service is a service in which a virtual desktop service provider provides a virtualized desktop environment to a user in the form of outsourcing.

A user can access a local office that provides a virtual desktop service using a user terminal, and can perform tasks such as executing an application program and storing data through a computing device provided in the local office. That is, an actual application program or the like is not executed or stored in the user's user terminal, but the application program or the like can be executed in the computing device in the local office. Here, the user terminal can display the execution result of the application program through streaming, and the user can check the execution result of the application program through this.

Since the user can execute an application program using a computing device of a local office, the user terminal can have only minimum performance such as decoding a streamed video and transmitting a user's input.

In addition, the user can receive the desired computing capability from the local office without needing to update the performance of the user terminal. That is, it is possible to receive and use as many resources as are necessary for the task to be performed.

In the case of a virtual desktop service, communication between a user terminal and a local office may be important, and depending on an embodiment, a dedicated line or the like may be installed to ensure a communication speed between a user terminal and a local office. For example, when a large number of users are concentrated, such as a company, a dedicated line may be installed between the company and the virtual desktop service provider, and then the service may be provided. Here, the dedicated line may be an optical communication dedicated line supporting 10 Gbps communication.

Meanwhile, in the case of providing a virtual desktop service, each local office corresponding to the location of the user terminal provides the virtual desktop service. In the case of corporations, since the location of corporate headquarters and research institutes is not easily changed, virtual desktop services can be continuously provided from the same regional bureau. That is, the user terminal and the local office may have a 1:1 correspondence relationship.

However, the number of subscribers subscribing to the virtual desktop service may be different for each region, or the computing resource usage of the virtual desktop used for each subscriber may be different. For example, in the case of local office A, 100 user terminals access each day, but in the case of local office B, only about 10 user terminals access each day. In this case, local office A may experience problems such as low service quality due to high traffic, but in the case of regional office B, computing resources provided in the local office may not be utilized and may be wasted. That is, a problem such as overall inefficiency of computing resources may occur.

Here, according to the virtual desktop service providing system according to an embodiment of the present invention, it is possible to efficiently utilize local offices because load balancing between respective regional offices can be performed. Hereinafter, a virtual desktop service providing system according to an embodiment of the present invention will be described in detail.

1 is a schematic diagram showing a virtual desktop service providing system according to an embodiment of the present invention.

Referring to FIG. 1, a virtual desktop service providing system according to an embodiment of the present invention includes a user terminal 1, local offices 10a, 10b, and 10c, a management server 100, and a resource management database 200. can include

Hereinafter, a virtual desktop service providing system according to an embodiment of the present invention will be described with reference to FIG. 1 .

The user terminal 1 is a terminal device used by a user to receive a virtual desktop service, and may be a device supporting wired or wireless communication. The user terminal 1 decodes and displays images received from the local bureaus 10a, 10b, and 10c, and controls signals applied by the user through input devices such as a keyboard, mouse, and touchpad. It can be transmitted to the local offices 10a, 10b, and 10c. Depending on the embodiment, a computer device such as a desktop computer, workstation, or laptop computer, or a communication terminal such as a tablet PC or a mobile phone PDA (Personal Digital Assistance) may be used as the user terminal 1. In addition, a dedicated device manufactured to receive a virtual desktop service may also be included in the user terminal 1 .

The user may perform user registration for use of the virtual desktop service in advance, and then transmit a request for access to the virtual desktop service using the user terminal 1 . When connected to the local bureau in response to the connection request of the user terminal 1, the user can receive a virtual desktop service from the computing resources of the local bureau through the user terminal 1.

The user can apply control input for executing each application program within the virtual desktop service using the user terminal 1, and the output for the operation of the application program can be provided in a streaming form from computing resources. . Accordingly, the user terminal 1 may decode the video streamed from the computing resource and provide it to the user. The user terminal 1 may include at least a display unit that outputs a decoded image, an input unit that receives a user's control input, and a communication unit that performs wired and wireless communication with computing resources or the management server 100 of a local office. there is.

The regional offices 10a, 10b, and 10c may be distributed and located for each region, and computing resources may be installed in each of the regional offices 10a, 10b, and 10c. Local offices (10a, 10b, 10c) may provide a virtual desktop service to the user terminal (1) by utilizing the installed computing resources.

Here, a virtual desktop service can be provided by local offices 10a, 10b, and 10c adjacent to the user terminal 1, and specifically, local offices included within a preset distance range based on the location of the user terminal 1 It can be set to adjacent local bureaus (10a, 10b, 10c).

When providing the virtual desktop service, the local bureaus 10a, 10b, and 10c provide images through streaming to the user terminal 1, and at this time, the distance between the user terminal 1 and the local bureaus 10a, 10b, and 10c The delay time may increase in proportion to . In this case, the quality of the virtual desktop service provided by the users receiving the virtual desktop service from the remote local office may deteriorate due to the delay time.

Accordingly, it is possible to limit the virtual desktop service to be provided to the user terminal 1 from neighboring local offices 10a, 10b, and 10c included within a preset distance range based on the location of the user terminal 1. Although FIG. 1 illustrates a case in which three adjacent local governors 10a, 10b, and 10c exist, it is not limited thereto.

Meanwhile, referring to FIG. 2 , the computing resources of the local offices 10a, 10b, and 10c may include a PC farm 11, a master image 12, and a dedicated storage 13.

The PC farm 11 is a plurality of integrated computing devices including a CPU (Central Processing Unit), memory, graphics card, etc., and each computing device performs operations such as various calculations or running application programs according to a user's request. can do.

The master image 12 may be a disk device including an operating system applied to drive each computing device integrated in the PC farm 11 . Here, the master image may combine various types of operating systems with a computing device according to a user's request, and depending on an embodiment, it is possible to include and provide a basic program such as a document editor in the master image.

The dedicated storage 13 is a data storage space corresponding to each user terminal 1, and data generated or downloaded by a user's operation may be stored. Here, the dedicated storage may be provided exclusively to correspond to each user.

When the local bureaus 10a, 10b, and 10c and the user terminal 1 are connected, the local bureaus 10a, 10b, and 10c use the computing device, master image 12, and dedicated storage 13 of the PC farm 11. By combining, a virtual desktop for the user terminal 1 can be formed, through which a virtual desktop service can be provided to the user terminal 1 .

Additionally, each of the regional offices 10a, 10b, and 10c can calculate a resource utilization rate, which is the ratio of computing resources in use among all available computing resources, and the calculated resource utilization rate to the management server 100 or the resource management database ( 200) and the like.

The management server 100 may connect each user terminal 1 to the corresponding local offices 10a, 10b, and 10c in response to the access request of the user terminal 1. At this time, depending on the number of user terminals 1 connected to the local offices 10a, 10b, and 10c, deviations in resource utilization rates may occur for each local office. Therefore, in the management server 100, a user terminal connected to each of the regional offices 10a, 10b, and 10c according to the resource utilization rate so that the deviation of the resource utilization rate between the regional offices 10a, 10b, and 10c does not occur significantly (1) can be adjusted.

Specifically, as shown in FIG. 4 , first, the management server 100 may receive a request for access to the virtual desktop service from the user terminal 1 . In this case, the management server 100 extracts the neighboring local bureaus 10a, 10b, and 10c included within a preset distance range from the location of the user terminal 1, and then extracts the resources of the neighboring local bureaus 10a, 10b, and 10c. Utilization rates can be retrieved. Thereafter, the local office 10a having the lowest resource utilization rate among the neighboring offices may be extracted, and the access address of the corresponding office 10a may be transmitted to the user terminal 1. Upon receiving the access address of the local bureau 10a, the user terminal 1 can access the corresponding local bureau 10a using the access address and receive a virtual desktop service from the local bureau 10a. That is, since the management server 100 can select a regional bureau to which the user terminal 1 accesses in consideration of the resource utilization rate between each regional bureau, the management server 100 provides the user terminal 1 to a specific regional bureau. ) can be prevented from converging, and the resource utilization rate can be evenly distributed among regional bureaus in the region.

However, if the resource utilization rate between the local offices 10a, 10b, and 10c is the same or the difference in resource utilization rate is less than a preset threshold value, the local offices 10a and 10b to be connected according to the distance to the user terminal 1 , 10c) can be set. As described above, the streaming used when providing the virtual desktop service increases the delay time in proportion to the distance from the user terminal 1 . Therefore, when the resource utilization rates among local stations are similar, it is also possible to minimize the delay time by connecting the user terminal 1 to the local office having the closest distance to the user terminal 1.

On the other hand, when the management server 100 sets the local bureaus 10a, 10b, and 10c to which each user terminal 1 accesses according to the resource utilization rate, the local bureaus 10a, 10b, and 10c are dedicated storage You need to share the data stored in For example, when the user terminal (1) accesses the virtual desktop service on November 14, it can be connected to the local bureau A (10a), and the user terminal (1) generates a document file X to obtain the local bureau A (10a). ) can be stored in dedicated storage. Then, on November 15, the user terminal 1 can access the virtual desktop service again, and at this time, the user terminal 1 can be connected to the local bureau B 10b. In this case, if the data between the dedicated storages of the local office A (10a) and the regional office B (10b) is not shared or synchronized, users who want to work on the document file X on November 15th will experience great inconvenience. can suffer

In order to solve this problem, the management server 100 may extract incremental data stored in the corresponding local bureau and transmit it to neighboring local bureaus 10a, 10b, and 10c when the user terminal 1 terminates the virtual desktop service. Here, dedicated storage corresponding to the user terminal 1 may be set in the plurality of neighboring local offices 10a, 10b, and 10c included within a preset distance range from the user terminal 1. Accordingly, when the user terminal 1 terminates the virtual desktop service, it is possible to transmit incremental data to the dedicated storage of a plurality of adjacent regional offices so as to be updated. Through this, the dedicated storage corresponding to the user terminal 1 of a plurality of adjacent local offices can always maintain a synchronized state, and the user terminal 1 always has the same dedicated storage even when connected to any local office in the region. can be provided.

Specifically, as shown in FIG. 2, the user terminal 1 may be connected to the local office A 10a to receive a virtual desktop service, and additionally generated between the time the virtual desktop service starts and the time it ends. The incremental data S may be stored in the dedicated storage 13. Thereafter, when the user terminal 1 stops accessing the virtual desktop service, local office A 10a transmits incremental data (S) to neighboring local office B 10b and C 10c, The dedicated storages 13 may be synchronized with each other. At this time, the management server 100 provides the local bureau A 10a with access addresses for each neighboring local bureaus, etc., and can control the local bureau A 10a to transmit incremental data (s). .

Also, depending on embodiments, it is also possible to synchronize incremental data in a manner as shown in FIG. 3 . That is, when the user terminal 1 stops accessing the virtual desktop service, the management server 100 may first receive and store the incremental data s. Thereafter, the management server 100 searches for access addresses of each neighboring local bureaus, and transmits incremental data (S) to the corresponding access addresses to synchronize the dedicated storage of each neighboring local bureaus.

The resource management database 200 may store a list of neighboring local bureaus, and may provide a list of neighboring local bureaus corresponding to each user terminal 1 according to a request of the management server 100 .

Here, in the list of neighboring local bureaus, for each user terminal 1, identification numbers of local bureaus 10a, 10b, and 10c located within a preset distance range from the user terminal and respective local bureaus 10a, 10b, and 10c ) may be stored. The access addresses of the local offices 10a, 10b, and 10c may be IP addresses, and depending on the embodiment, the resource utilization rate of each of the local offices 10a, 10b, and 10c may be updated and stored at predetermined intervals. . On the other hand, an embodiment in which a preset distance range is differently applied to each user terminal 1 is also possible.

The neighboring local bureau list can check the location information of the user terminal 1 through the GPS information or IP address of the user terminal 1, for example, the local bureau included within a radius of 10 km from the user terminal 1 ( 10a, 10b, 10c) can be set as neighboring region bureaus.

In addition, depending on the embodiment, the administrative district in which the user terminal 1 is located may be collected as location information, and then, the local government office 10a included in the same administrative district as the user terminal 1 or an adjacent administrative district. , 10b, 10c) is also possible to set as neighboring regional offices. For example, in the case of the user terminal 1 located in Gwanak-gu, Seoul, local government offices located in Gwanak-gu and Dongjak-gu, Seocho-gu, Geumcheon-gu, and Yeongdeungpo-gu adjacent to Gwanak-gu may be set as neighboring regional offices.

As shown in FIG. 1, the resource management database 200 may be provided separately from the management server 100, but may be included in the management server 100 according to embodiments.

5 is a flowchart illustrating a virtual desktop service providing method according to an embodiment of the present invention.

Referring to FIG. 5, the method for providing a virtual desktop service according to an embodiment of the present invention includes a step of receiving a connection request (S10), a step of connecting a local office (S20), an incremental data extraction step (S30), and an incremental data sharing step (S40). ) may be included.

Hereinafter, a method for providing a virtual desktop service in a management server according to an embodiment of the present invention will be described with reference to FIG. 5 .

In the access request receiving step (S10), the management server may receive an access request for the virtual desktop service from the user terminal. The user may transmit an access request through the user terminal in order to use the virtual desktop service. At this time, the access request of the user terminal may be transmitted to the management server.

In the local office connection step (S20), the management server may connect the user terminal to the computing resource of the corresponding local office according to the access request of the user terminals. The access request transmitted by the user terminal may include identification information corresponding to each user terminal. Therefore, the management server can distinguish each user terminal by using the identification information, extract a local bureau corresponding to the user terminal, and connect it to the computing resources of the corresponding local bureau.

Specifically, the management server may extract neighboring area bureaus of the user terminal from a list of neighboring area bureaus, and may connect the user terminal to the extracted neighboring area bureaus. Here, the neighboring area offices may be area stations included within a preset distance range from the user terminal.

Depending on the embodiment, it is also possible to allocate a local office to be accessed by the user terminal according to the extracted resource utilization rates of neighboring regional offices. That is, when the management server receives an access request from the user terminal, first, it can check the resource utilization rate of each neighboring regional bureau in real time, and connect the user terminal to the neighboring local bureau with the lowest resource utilization rate. Through this, it is possible to balance loads between neighboring regional offices.

In the incremental data extraction step (S30), when the user terminal terminates access to the virtual desktop service, the management server may extract incremental data added to the dedicated storage of the user terminal included in the computing resources. The same virtual desktop service must be provided even when the local offices to which the user terminal accesses are changed. That is, in order to synchronize the dedicated storage between a plurality of regional bureaus, in the incremental data extraction step (S30), incremental data added to the dedicated storage can be extracted when the connection to the virtual desktop service is terminated. Here, the incremental data may be data additionally stored in the exclusive storage between when the user terminal accesses the virtual desktop service and when the connection is terminated.

In the incremental data sharing step (S40), the management server may transmit incremental data to each neighboring local bureau included in the neighboring local bureau list corresponding to the user terminal. Through this, the dedicated storage of adjacent regional offices can be synchronized.

Specifically, the incremental data sharing step (S40) can be implemented in two embodiments, as shown in FIG.

As shown in FIG. 6(a), first, the management server may receive and store incremental data from the local bureau (S411), and the management server may request a list of neighboring local bureaus from the resource management database (S412). The list of neighboring local bureaus may include identification information of neighboring local bureaus located within a preset distance range from the user terminal, access addresses of the neighboring local bureaus, and the like. Accordingly, the management server can identify neighboring regional bureaus to transmit incremental data to through the list of neighboring regional bureaus, and can also identify access addresses for them.

Thereafter, the management server may extract access addresses corresponding to respective neighboring local bureaus from the list of neighboring local bureaus (S413), and may transmit incremental data to neighboring local bureaus using the access addresses (S414). Each of the neighboring local bureaus that have received the incremental data can update the incremental data in the dedicated storage corresponding to the user terminal using the received incremental data.

In addition, as shown in FIG. 6(b), the management server first requests a list of neighboring local bureaus from the resource management database (S421), and extracts access addresses corresponding to respective neighboring local bureaus from the list of neighboring local bureaus. It can (S422). Thereafter, the management server provides access addresses of neighboring bureaus to the local bureau where the user terminated the virtual desktop service, so that the local bureau can directly transmit incremental data to the neighboring bureau (S423).

The present invention is not limited by the foregoing embodiments and accompanying drawings. It will be clear to those skilled in the art that the components according to the present invention can be substituted, modified, and changed without departing from the technical spirit of the present invention.
