It relates to a method and a system.

Instance messenger service For example, a plurality of servers are operated to provide KakaoTalk, Line, and the like. The server transmits data such as conversations, photos, videos, and voice files transmitted by each user to other users. The instant messenger service will continue to increase due to the generalization of smart devices and the development of network technology, and the user and usage rate will also increase infinitely.

The data delivered by the server of the instant messenger service is likely to be very personal information due to the nature of the instant messenger service. Therefore, the instant messenger service provider does not always store conversations, photos, videos, and voices transmitted between users, but only retains them for a certain period of time, for example, one to two weeks, and permanently deletes old data. have. In addition, data such as conversations, pictures, videos, and voices to be transmitted may be encrypted, and the data is secured so that the data cannot be accessed unless an authorized user. Here, the allowed user is a chat invite invited to the chat window. In other words, the data in the instant messenger service is not provided to anyone other than the chat partner invited to the chat window.

The instant messenger service has a higher rate of service requests per second than other types of services. However, since the size of the request data is small, the instant messenger service has not suffered any problems.

However, due to the generalization of smart devices, since the size of the request data has increased exponentially and the request rate is higher, the instant messenger service provider continues to expand the high-end server to cope with this. As server expansion increases power consumption as well as maintenance costs, it is very important to manage data efficiently on the server.

Therefore, there is a need for a data management method that can minimize performance degradation and improve efficiency in an instance messenger server.

Figure 5 shows a flow diagram of one embodiment further operation of the method according to the invention.

Figure 6 shows a further operational flow of another embodiment of the method according to the invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the embodiments. Also, like reference numerals in the drawings denote like elements.

The server providing the instant messenger service is responsible for delivering a talker's conversation, picture, video, voice, etc. to a contact or conversation member in the same chat room. At this time, since the number of conversation members is determined, the server rarely transmits data again after transmitting the determined number.

Of course, the user may look up the previously downloaded or sent photos again, but in this case, since the data is retrieved from the cache space of the device without requesting the server, it is irrelevant to the server. That is, after transmitting data as many conversation members, the server stores data only for unusual situations such as retransmission requests due to internal policies and network errors. This data does not have to be stored on a high-performance server, and migration to backup disks does not affect quality of service.

Embodiments of the present invention consider the time at which data is generated in the server providing the instant messenger service (the time the conversation member uploaded the data and received at the server, the request rate (or access rate), the number of conversation members, the number of downloads, etc.). By managing the data, it is possible to minimize the performance degradation of the server and improve the efficiency of resource usage, and to reduce the capital investment cost, maintenance cost, and power consumption of the instant messenger service.

The instant messenger service is an example of a closed data sharing service. The present invention is a closed data sharing service data management method and system, which will be described in detail using the instant messenger service.

Referring to FIG. 1, a system 100 according to the present invention includes a first server 110 and a second server 120.

The first server 110 is a main server that provides an instance messenger service, and may be a high performance server that stores data having a high request rate.

Here, the first server 110 is a main server that provides an instance messenger service, for example, KakaoTalk, Line, etc., and creates a chat room in which users, for example, user A, user B, and user C, are conversation members. Receiving and storing data transmitted or uploaded by a chat member of a chat room, for example, voice, file, video, photo, etc., and providing data sent by the member to another member upon request by another chat member. can do.

The first server 110 creates a chat room for a plurality of chat members, receives and stores the uploaded data when data is transmitted or uploaded by one of the chat members of the chat room, for example, user A, If the stored data has elapsed for a predetermined period of time, e.g. within one to two weeks, for all remaining conversation members, whether downloaded by User B, User C, or downloaded by a member, for example, Move and save the data to the second server and delete the stored data.

That is, the first server 110 determines that the data is the old data (cold data) when all of the conversation members are downloaded by the chat members in a state in which the data is not generated at a point in time when the data is generated, and the second server as the backup server. By moving to the server 120 and storing the data and deleting the data stored in the first server 110, performance degradation of the first server 110 may be minimized and resource efficiency may be improved.

Of course, if the data to be transmitted by the server passes a certain period from the time of generation or if the request rate is greater than or equal to a certain size, the first server 110 determines that this data is also old and moves the corresponding data to the second server 120. The data may be stored and deleted from the first server 110.

The second server 1210 is a backup server that stores data determined by the first server 110, for example, old data. The second server 1210 has a lower performance than the first server 110, but is not included in the first server 110. It is a server with good efficiency.

The second server 120 may provide the stored data to the first server 110 when requested by the first server 110, and provide downlink information on the stored data to the first server 110 or correspondingly. Data can also be sent to the requesting user device.

As described above, the first server 110 is cold data when the age of the data to be transmitted by the server (time or period elapsed from the time of data generation) passes a certain period or the request rate passes a certain size. In addition to moving to the second server 12 which is a backup disk as well as the number of conversation members, it is determined to be old data regardless of age and request rate, and is moved to the second server 120 for storage. Thus, efficiency can be improved while minimizing performance degradation of the first server 110.

Although FIG. 1 illustrates the case where the instant messenger service system is configured with two servers, an example messenger service system may include a plurality of servers if not limited thereto. That is, FIG. 1 illustrates only two layers using only two servers, but may have two or more layers, and a policy for distributing and storing data in each layer may be a policy.

For example, a first server, which is a main server providing an instance messenger service, and a plurality of backup servers according to the type of transmission data may be configured. That is, the instant messenger service system may be configured to include a backup server according to data type such as a high performance server, a video data backup server, a voice data backup server, a photo data backup server, and the like. Such a system according to an embodiment of the present invention may be applied to a distributed file system. The distributed file system divides and replicates a file or data to be stored and stores the data in multiple storage servers. The storage file system follows a predetermined policy. These policies vary greatly depending on the type of distributed file system, and the policies can affect the performance and efficiency of the server.

Because the instant messenger service is very different from other services, it is advantageous to use a separate policy rather than a general policy. Therefore, by considering the number of conversation members, it is possible to minimize the performance degradation of the server and improve efficiency. .

FIG. 2 shows an embodiment configuration of the first server shown in FIG. 1.

Referring to FIG. 2, the first server 110 includes a generator 210, a storage 220, a determiner 230, a determiner 240, and a provider 250.

The generation unit 210 generates a chat room for the instance messenger service.

Here, the chat room may be created at the request of users using the instant messenger service, and the chat members constituting the chat room may be at least two people. Of course, the chat room may be configured as one person when a plurality of conversation members constituting the chat room leave the chat room.

The storage unit 220 receives and stores data uploaded or transmitted by one of the plurality of conversation members constituting the chat room, and the uploaded data has data having a predetermined size or more, such as voice, video, or photo. Can be.

At this time, the storage unit 220 may store various software, data, etc. for providing an instant messenger service, and may store data for performing the present invention.

The determination unit 230 determines whether the uploaded data has been downloaded by all remaining conversation members within a predetermined period of time, and whether or not it is old data.

For example, the determination unit 230 uses the request rate (or access rate) for downloading data and the number of conversation members, and if the number of downloads is equal to the number of remaining conversation members for a predetermined period from the time of data upload, all remaining conversation members are uploaded. For example, it may be determined that the data has been downloaded.

That is, the determination unit 230 may determine whether the data is downloaded by all the remaining chat members for a predetermined period from the time when the uploaded data is stored, and when the data is downloaded by all the other chat members, the determination unit 230 may determine the corresponding data as old data. have.

If the data is downloaded by all remaining conversation members within a predetermined period of time as a result of the determination by the determination unit 230, the determination unit 240 determines the movement of the uploaded data to a predetermined specific server, that is, the second server.

In this case, the determination unit 240 may delete the data after moving the data to the second server and storing the data at the time when the data is downloaded by all remaining conversation members.

If the data transmitted by the member is not downloaded by the rest of the conversation members for a certain period of time, the determination unit 240 determines the data as old data, thereby moving the data to the second server and storing the data and deleting the data. do.

The provider 250 downloads the data stored in the second server when the data is requested by the chat member while the data is not downloaded by all the other chat members and the data is moved and stored in the second server. In order to do so, it provides downlink information about the data to the conversation members. That is, the member can directly download the data from the second server using the downlink information.

Furthermore, the provider 250 may receive the corresponding data stored in the second server and provide the corresponding data to the corresponding conversation member. For example, the provider 250 sends the data to the second server when the data is requested by the chat member while the data is not downloaded by all the other chat members and the data is moved and stored on the second server. Request and receive from the second server and provide the corresponding data to the conversation member. Of course, when the data is provided to the chat member, the data may be deleted at the first server.

Data management in the first server including such a configuration will be described with reference to FIG. 3 as follows.

As shown in FIG. 3, when data having a predetermined size or more, such as a voice, a photo, a video, or the like is transmitted or uploaded by one of the chat members of a chat room, the data uploading time t1 to a predetermined time period T. Determine if the data uploaded by the remaining members has been downloaded.

When the uploaded data is downloaded by all the remaining members at time t2, the first server determines that the data is old because all the members have downloaded the uploaded data, and at the time t2, the second data is determined. It moves to the server and stores it, and deletes the corresponding data from the first server.

On the other hand, if a predetermined period (T) has elapsed while the uploaded data is not downloaded by all members, the first server determines the data as old data at time t3 and moves the data to the second server for storage. Delete the data from the first server. After a certain period of time, the data stored in the second server may be provided to the chat member by request of the chat member after the corresponding time.

As described above, the system according to the present invention manages data in consideration of the number of conversation members in the first server, which is a high performance server, thereby minimizing performance degradation of the first server and improving efficiency using the second server. In addition, such data management can reduce server maintenance costs, operating costs, and the like.

As described above, the system according to the embodiment of the present invention arranges a file on a first server, which is a high performance server, records the number of times while transferring the file, and if the number of conversation members is equal to or larger than the remaining conversation members, Regardless, use a policy to move and store the second server as a backup server. This allows you to migrate unnecessary files to a more efficient server faster, resulting in high efficiency without compromising performance.

4 is a flowchart illustrating an operation of a method for managing instant messenger service data according to an embodiment of the present invention, which is a flowchart illustrating operations of the first server 110 illustrated in FIGS. 1 and 2.

Referring to FIG. 4, the method according to an embodiment of the present invention creates a chat room for a plurality of chat members by a user request (S410).

When the data is uploaded or transmitted by one of the chat members of the chat room, the uploaded data is received and stored, and it is determined whether the corresponding data is old by determining whether the data is out of date (S420, S430).

Here, the target data for determining whether the old data is data having a size or more than a predetermined capacity may be data such as a voice, a picture, a video, and the like.

At this time, if it is determined in step S430 that the corresponding data has elapsed for a predetermined period of time from when the data is uploaded or when the data is stored, the data is determined to be old data, and the data is determined in advance as a specific server. After moving to the second server 120 of FIG. 1 and storing the data, the corresponding data stored in the first server is deleted (S450 and S460).

If the corresponding data has not passed a certain period by step S430, it is determined whether the corresponding data has been downloaded by all members of the chat room, that is, members other than the members who uploaded or transmitted the data with respect to the corresponding data (S440). .

That is, step S440 is a step for determining whether the corresponding data is old data or not by downloading all the conversation members in a state in which the predetermined time has not elapsed.

If it is determined in step S440 that the data has not been downloaded by all members, the process is fed back to step S430 to determine whether the data has passed a predetermined period. By judging the data as old data, the data is moved to a predetermined server, for example, the second server 120 of FIG. 1 at this point in time and stored, and then the corresponding data stored in the first server is deleted (S450, S460).

FIG. 5 shows a flow chart of an embodiment of further operation of the method according to the present invention, and shows a flow chart of an embodiment of the providing unit 250 shown in FIG. 2.

As shown in Fig. 5, the method according to the present invention requests the download of the data by the chat member while the data is not downloaded by all the rest of the chat members of the chat room and the data is moved and stored on the second server. If received, the downlink information of the corresponding data is provided to the corresponding conversation member so as to download the corresponding data stored in the second server (S510 and S520).

As described above, FIG. 5 is a process of directly downloading the corresponding data from the second server using the downlink information of the corresponding data.

FIG. 6 shows a flow chart of another embodiment of the method according to the present invention, showing an operation flow of another embodiment of the providing unit 250 shown in FIG.

As shown in Fig. 6, the method according to the present invention requests the download of the data by the chat member while the data is not downloaded by all the rest of the chat members of the chat room and the data is moved and stored on the second server. When the received data is received, the corresponding data stored in the second server is requested to the second server so as to download the received data, and the received data is provided to the corresponding conversation members (S610 and S620).

At this time, if the corresponding data is provided to the chat member by step S620, the corresponding data may be deleted from the first server.
