The present invention relates to a method for effectively sharing and transmitting data using a web folder and a P2P system.

A general P2P system is a system in which all participants are suppliers and consumers by directly connecting and searching individual computers without going through an intermediary server. The amount of data shared increases exponentially as users increase. However, it has the disadvantages that the reliability of data (incomplete data) and the stability of the line are inferior to the existing C / S (client / server) system.

The present invention is a problem of the P2P system as described above 1) when the P2P system receiving data to download untrusted data (partitioned and incomplete data) to wait indefinitely to turn on the system, 2) providing data If a computer equipped with a P2P system cannot transmit due to an unexpected reason during data transfer, 3) The computer equipped with the P2P system providing the data cannot access another P2P system due to a firewall or network problem. If you can not provide, such as 3) times to compensate for the problem by uploading (transmitting) the data you want to share in their own web folder to the P2P network,

When searching the data in the P2P system to receive the data, it is classified and provided by the individual (peer, person) or from the web folder of another person. By providing high quality web folder data (data), it solves the problems of 1) and 2).

When downloading data shared on a P2P network, users were given the option to set the path to a web folder rather than their own computer with a P2P system, leaving the personal computer on and waiting for all of the data to be downloaded. It effectively complements the problem.

In general, the Internet refers to the world's largest computer communication network, which originated from the Alphanet (ARPANET). It has evolved from the interconnection of small-scale networks such as LANs, and now it is an aggregation of huge networks all over the world.

This Internet basically developed through the C / S (referred to as C / S below the Client / Server) system (Fig. 1), such a C / S system, collects, stores or processes the service or information provided It is characterized by consisting of a server (Server) and a number of clients (Client) to be provided.

In case of C / S system, all requests are handled by server, so it is easy to manage and maintain, and it can provide stable and reliable communication environment according to line or server performance. It is true that there is a limit to the processing power.

There are two main types of P2P system. One is a hybrid P2P system method that realizes personal connection with the help of a server to some extent, and the other is a pure P2P system method that directly connects without a server by sharing personal information such as an IP address in advance among clients. . In the case of a hybrid P2P system, after the access and search step, individuals share and exchange information directly as in the case of a pure P2P system.

Hybrid P2P system is also referred to as a centralized direct communication P2P system, and has a structure as shown in FIG. In order to efficiently manage and supervise the distributed network of computers equipped with P2P system, the main server is intervened. 3 is an indirect network diagram of this type of hybrid P2P system.

In a hybrid P2P system, the P2P system is connected to the main server at the same time as it is running, and sends information of the computer where the P2P system is installed to the main server.

In the main server, in order to efficiently manage the distributed network to which such P2P system is connected, the information (IP address, etc.) of the computer where the P2P system is installed is stored in DB and stored in the DB. It queries the P2P systems stored in the server DB and sends the result directly to the requested P2P system.

Based on the information, the received P2P system can directly access the P2P system that holds the data (data) to download (transmit) the data (data).

Hybrid P2P system can reduce unnecessary network waste by storing information of computers equipped with P2P system on the main server in database, but the whole service is impossible if the main server is not connected unexpectedly. .

The pure P2P system is also called a distributed distributed network system, and has a structure as shown in FIG. 4. Pure P2P system has no medium to act as broker in the middle, and has complete server and client that can connect network with each other in Pure P2P system program.

Pure P2P system programs connected to the P2P network are connected to each other like the network as shown in FIG. 4 to exchange their own information, and to continuously update and update the information of the pure P2P system programs independently connected to each other. It is possible to have a distributed distributed network by storing and storing it.

Data search and transmission of Pure P2P system are as follows. As soon as the P2P system program is executed, it automatically or manually accesses the P2P system program belonging to the P2P network, and exchanges the information of the P2P system programs included in the P2P network and stores them in their own database.

When a pure P2P system program tries to find data (data), it asks whether it has specific data (data) based on the computer information loaded with the pure P2P system program stored in its own DB. The computer equipped with the received pure P2P system program propagates to another computer by referring to its own DB and searches for the existence of specific data (data) in its shared file. Sends a message for direct access to a P2P system program for download (transmission).

Pure P2P system is characterized by the fact that if there is a computer with Pure P2P system program in P2P network, it can continue to provide the service without depending on the specific device (main server, single user.) It is a method that connects and delivers queries one by one, which results in slow network due to heavy network consumption.

P2P system has the advantage that the shared data (data) increases exponentially as users increase in common, but stability and reliability according to the situation of a computer equipped with a P2P system that provides a line or data (data) There is a drawback that the data is broken because it is divided.

Direct communication between individuals using the web shared backup storage device (Public Patent Application No. 2002-0046410) backs up (stores) all or a part of data to be shared on the P2P network to the web backup device, thereby causing the P2P system to be inevitable due to the P2P system. If you can't access the network, it will automatically switch to the web backup storage device to take over the role.

This method provides a stable communication environment by switching the path to the main server, which is a web backup device based on the C / S system concept.However, all or part of the data (data) shared by the P2P system can be used. It has a limitation of storing data (data) due to copyright law and "limit of server capability" which is a disadvantage of C / S system by sharing (backing) by sharing to main server. In addition, it only provides (shares) data backed up (stored) in its web backup device to the P2P network, and saves data (data) uploaded on the P2P network only on a computer equipped with a P2P system through its own P2P system. Because it cannot be stored in the web backup storage device, it has a disadvantage in that it cannot fulfill its role as an independent auxiliary storage device which is a characteristic of the web backup storage device.

An object of the present invention for solving the above problems is to provide a stable and reliable P2P system effectively using a P2P system and a web folder.

Another object of the present invention is a computer equipped with an indefinite P2P system until all data is transmitted in order to download untrusted data (partitioned and incomplete data) by a P2P system receiving data (data) in a P2P network. If you need to wait for a web folder to act as an independent secondary storage device on behalf of the task, it provides a way to compensate for the existing problem of having to wait for the personal computer to be turned on.

Another object of the present invention is to solve the existing problem that the computer equipped with a P2P system for providing data (data) could not transmit the data (data) due to unexpected reasons, P2P system to receive data (data) When searching for this specific data (data), the list window indicates whether it is provided by a person (peer, person) or another person's web folder. By providing the web folder's data, it provides a way to complement the stability and reliability of the existing P2P system.

Another object of the present invention is to upload and share files in their web folder when a P2P system that provides data (data) is unable to connect to another P2P system because of a firewall or other network problem or when the computer is turned off. By providing a way to continuously share on behalf of your own P2P system.

The present invention combines the advantages of a P2P system and a web folder, and gives the option to share the material to be shared on a computer or web folder equipped with a P2P system, and the computer or the computer equipped with the P2P system By giving you the choice of whether or not to be sent to your web folder, you'll provide a more convenient, stable, and reliable way.

DETAILED DESCRIPTION Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Detailed descriptions of some of the components related to the overall understanding of the present invention will obscure the subject matter of the present invention and will not be described in detail if it is apparent to those skilled in the art.

6 is a diagram illustrating a connection between a P2P system and a web folder.

The P2P system 50 is divided into a server 12, a client 13, and a web client 13, and the server 12 and the client 13 interwork with a P2P network by using a connection interface 11 of the P2P system. In the form of a pure P2P system (FIG. 5) to share data (data) while interlocking with other P2P system 50 with each other in the form of the same, the web client 13 mounted in the present invention is the main server of the web folder After connecting to the web folder storage device 51 of the user through the connection interface 31 of 52, the data (data) to be stored is uploaded (transmitted) or downloaded (transmitted). If the user selects and sets the data (data) to be shared from the web folder to the P2P network network among the data (data) stored in the web folder, the own web folder storage device 51 selects the data (data) selected in the share file 21. ) And the own share list is stored in the DATA management DB 53 managed by the web folder main server 52 for efficient sharing management.

7 is an overall network diagram connecting a P2P system and a web folder.

In FIG. 7, the data request is divided into a P2P system 50a and a data providing P2P system 50b to help understand the data. However, the data is provided in the same system. In the web folder 51b of the P2P system 50b and the data providing P2P system 50b, it is assumed that the data to be shared may be different from each other, but for convenience.

Assuming that the data request P2P system 50a searches for specific data (data) in FIG. 7, the data request P2P system 50a is specified as a server of the data providing P2P system 50b connected to its client 13. The web client 14 of the data request P2P system 50a requests the data search through the web folder main server 52. The requested data providing P2P system 50b and the web folder main server 52 retrieve their shared data (data) and transmit the result message to the data requesting P2P system 50a. At this time, the data providing P2P system 50b searches for data shared by its own computer and sends metadata including IP address, file information, etc. so as to directly access to its own server. The web folder main server 52 searches for the data management DB managed by the web folder main server 52 to check whether the data exists in the share file of the web folder 51b. Metadata containing information, file information, and the like is transmitted to the web client 14 of the data request P2P system 50a.

The data request P2P system 50a, which has received a message from the web folder main server 52 and the data providing P2P system 50b, clearly indicates the source of the data and gives the user the option of where to receive the data.

8 is a flowchart of data (data) of a P2P system and a web folder.

In FIG. 8, the data request P2P system 50a and the data providing P2P system 50b are divided to provide an understanding, but are actually the same system, and the provision and request of the data are determined according to the user's request and the state of the system. In the web folder 51b of the provided P2P system 50b and the data providing P2P system 50b, the data to be shared may be different, but it is assumed that they are the same for convenience.

In FIG. 8, when the data request P2P system 50a makes a data search request to the data providing P2P system 50b and the web folder main server 52 to search for specific data (data), the data providing P2P system 50b is provided. Search the shared list in his system, the web folder main server 52 searches the share file of the web folder 51b that provides data through the DATA management DB managed by the main server 52 Each result is transmitted to the data providing P2P system 50a.

When the data request P2P system 50b tries to download (transfer) data (data) of the data providing P2P system 50b with reference to the received information, the data request P2P system 50a receives the data providing P2P system ( 50b) direct access to the server 12 can be downloaded (transfer) to the computer equipped with his own data request P2P system (50a), such as in the form of 1a, or his web folder storage ( 51a) may be downloaded (transmitted). In the case of downloading (transmitting) to the web folder 51a of its own in the form of 1b, the computer equipped with the data request P2P system 50a is represented by the web folder 51a on behalf of the specified material even if the P2P system is turned off. Data) is downloaded (transmitted). After completing the transmission, the user can download (transfer) the data transmitted from his web folder through the web client mounted in the P2P system 50a.

If you download (transfer) data from the web folder 51a of another person, you can download (transfer) it to the computer equipped with the data request P2P system 50a as in the form of 2a, You can also download (send) data to your web folder. In the case of the 2b form, since the work is performed on the web folder main server 52, it is true that the data is copied rather than called down (transfer). After the transfer is completed, the user requests a data request from his web folder. Can be downloaded (transmitted) through the web client.

9 is a flowchart of storing and sharing data (data) of a web folder.

The P2P system must first connect to the main server and log in 1001 to store and share data in its web folder. Through this process, it acquires the right to save and share data (data) in the web folder, and obtains information (IP address, etc.) of P2P systems belonging to the P2P network, connects to the P2P network, and searches for data by itself. You can share. The P2P system authenticated by logging in may upload (transmit) 1002 a specific folder or file to its web folder.

Only data uploaded (transmitted) is completed, and the user directly selects data (data) to share in the P2P network and sets the sharing setting (1003). The web folder storage device adds the data (data) selected for sharing to the data management DB managed by the web folder main server (1004). When the data request P2P system requests the data search, the web folder main server searches the DB managed by the main server through the data management interface and transmits the result.

10 is a flowchart of data (data) sharing in a P2P system.

At the same time as the P2P system starts, the client of the P2P system uses the information of P2P systems (IP address, etc.) belonging to the P2P network obtained from the web folder main server or the accumulated P2P systems (IP address, etc.). Connect to the network 1101. Through this process, the authority to share data (data) of a computer equipped with a P2P system is given.

The user directly selects the data to be shared among the data (data) of the computer equipped with the P2P system and sets the share 1110 to add it to the share list through the data management interface of the P2P system (1103). The P2P system waits (1106) while the server of the P2P system is running (1105), and if there is a P2P system requesting data, the P2P system receives the data retrieval request through the running server and searches its shared list. The result is sent as a message to the requesting P2P system.

11 is a flowchart of data (data) search and download (transmission) of a P2P system.

The P2P system accesses the web folder main server and the P2P network in order to retrieve and transmit specific data (data), and then goes through an authentication process through logins 1201 and 1202. In fact, the user goes through the login process only once, but it should be noted that it is shown separately to help understand the independent execution of the web folder and P2P system. Through this process, the P2P system accesses the web folder main server 1201 using the web folder of the P2P system, and acquires the right to store and share data (data) in its web folder. In addition, the P2P system independently connects to a computer equipped with another P2P system, exchanges information with each other, and connects to each other to share data (data) existing in a computer equipped with a P2P system in a P2P network formed in the same form as a pure P2P system. You can do it.

After completing the connection and authentication process, the P2P system searches for necessary data (1203) and makes a search request to the web folder main server and other P2P systems belonging to the P2P network (1203). The web folder main server that received the search request searches the data management DB managed by the user and searches the shared data (data). If the data exists, it transmits metadata containing the information (data), owner, etc. P2P system belonging to the P2P network that is independently requested to search and search for its own shared data (data) and, if present, the information about the data and the information of the computer equipped with the P2P system (IP address, etc.). The metadata is transmitted to the P2P system that requested the search (1204). In the search result list of the P2P system requested for searching in the above manner, whether the data (data) to be searched exists in the web folder of another person or in another P2P system belonging to the P2P network is clearly distinguished and displayed (search of FIG. 16). The list pane will help you understand it (it's attached here to help you understand it, so I won't explain it in detail).

With reference to this result, the user selects 1207 whether to transmit the retrieved data (data) to a computer equipped with his or her own P2P system or a web folder of the P2P system, as shown by the solid and dashed arrows in FIG. 16.

When saving the data (data) retrieved in the above operation to the web folder of the P2P system, the web folder is an independent auxiliary device of the computer with the P2P system installed, and the web folder main server transfers the data (data) on behalf of the computer with the P2P system installed. It is possible to turn off the computer or the P2P system with the P2P system is installed (1208). After the data transfer is complete, you can download it from your web folder.

On the other hand, when storing data to a computer equipped with a P2P system, the client of the P2P system requesting the data directly connects to the server of the P2P system providing the data and transmits the data (data) to the computer equipped with the P2P system. In this case, according to the system situation of the P2P system providing the data, the P2P system should wait 1210 until the transmission is completed. If the P2P system that provides the data is unable to transmit due to unexpected events during the data transmission, the same data (data) among the data (data) shared in the P2P network is automatically searched for and transferred. The P2P system that provided the service is restored and takes over the data (data) provided by waiting for reconnection to the P2P network.

12 is a search flowchart of a P2P system when a data (data) search query request is made.

Data request P2P system uses its client to inquire 1302 whether P2P systems connected to it 1130 exist, and the requested P2P systems propagate to other P2P systems to the P2P network. All P2P systems at will be queried. P2P systems that have been requested to search for data retrieve the shared list through the data management interface of the P2P system on the computer equipped with the P2P system (1303) and if the data is present (1404), the P2P system loads its own P2P system to the first data request P2P system. Metadata including information of a computer (IP address, etc.) and data (data) is transmitted (1305).

13 is a flowchart illustrating a search of a web folder when a data (data) search query request is made.

Data request P2P system connects to the web folder main server (1401) using its web client and inquires (1402) whether the data to be searched for exists in the web folder main server. If the data exists (1404) by searching (1403) the data management DB (a set of data included in the share file of the web folder with the user's shared setting), the P2P system requesting the data search is requested. Metadata containing information about the owner of the (1405) is transmitted.

14 is a flow chart of a web folder (web auxiliary storage device) when a data (data) request is sent.

The data request P2P system assumes that the data (data) provided from the web folder of another person is downloaded (transmitted) by referring to the result obtained by searching for the desired data in the same manner as in FIGS. 13 and 14. The P2P system accesses the web folder main server 1501 by using the web client of the P2P system and requests data.

The web folder main server searches its own managed data management DB (a set of data included in the share file of the web folder that the user has set up for sharing) (1502), and the web folder main server can transmit data (data). Check whether the data to be transmitted exists (1503), and then transmit the data to the P2P system that requested the data. If the transmission is unavoidably interrupted due to an unexpected situation of a computer equipped with a P2P system during the data transmission, the data transmission can be completed later using the resume function.

15 is a transmission flowchart of a P2P system when a data (data) request is sent.

Data Request P2P system assumes that the data (data) provided by the P2P system belonging to the P2P network is downloaded (transmitted) by referring to the result obtained by searching for the desired data in the same manner as in FIG. 13 and FIG. 14. The requesting P2P system uses the client of the P2P system to make a connection permission request 1601 to the server of the data providing P2P system. Data Provision The P2P system grants permission (1602) in consideration of its system situation (excess number of clients, line overload, etc.), and the data request from the P2P system is shared through its data management interface. The search for a list of the data to be found (1603). Based on the search result, the data request P2P system checks whether the data (data) required, if any, exists and is available for data transmission (1604), and starts the data transmission (1605) using the client of the data request P2P system. Done.

As described above, according to the present invention, 1) the P2P system, which is a problem of the P2P system, needs to wait for the system to be indefinitely in order to download untrusted data (partitioned and incomplete data). 3) If a computer equipped with a P2P system that can provide data cannot be transmitted for an unexpected reason during data transmission, 3) A computer with a P2P system that provides data may access another P2P system due to a firewall or network problem. If you can't provide data because you can't provide data, you can upload (transfer) the data you want to share to your web folder and share it on a P2P network as a substitute.

When searching the data in the P2P system to receive the data, it is classified and provided by the individual (peer, person) or from the web folder of another person. By providing high quality web folder data (data), it solves the problems of 1) and 2).

 When downloading data shared on a P2P network, users were given the option to set the path to a web folder rather than their own computer with a P2P system, leaving the personal computer on and waiting for all of the data to be downloaded. It can effectively solve the problem.
