The present invention relates to a method and system for providing wired / wireless unified storage service using peer-to-peer communication (P2P). More specifically, in order to provide a unified storage service that can be used together with a wired user terminal and a wireless mobile communication terminal, a virtual peer for a wired or wireless peer such as a mobile communication terminal and a user terminal is created and virtualized. The present invention relates to a method and system for providing a wired / wireless integrated storage service for allowing a peer to store, retrieve, request, and download data using P2P and ultimately perform P2P between peers on a wired or wireless network.

Due to the development of the Internet, services that use a large amount of content and data such as a multimedia broadcasting service (MBS), a video telephony service, and an online game service using the Internet have been spotlighted by Internet users. . These high-capacity content and data services require a lot of storage space and cause high specification of users' terminals. A service to overcome this limitation is storage service.

1 is a block diagram schematically illustrating a storage service system on the Internet.

The storage service system on the Internet includes a user computer 110, the Internet 120, a storage server 130, and a storage space 140.

The user computer 110 refers to a plurality of desktop computers or notebook computers with a built-in web browser capable of accessing the Internet. The user computer 110 searches for data, downloads data, and stores data. The Internet 120 refers to a global open computer network architecture that provides the TCP / IP protocol and various services that exist at the upper layer. The storage server 130 stores and provides data such as applications and multimedia at the request of the user computer 110. The storage space 140 stores data such as an application and multimedia received from the user computer 110 under the control of the storage server 130.

Internet users do not back up large amounts of data using portable storage devices, but use storage services to access the storage server 130 through the Internet 120, and then transfer and store large amounts of data. Move it or access the storage server 130 again in the required time to download a large amount of data to perform the task. That is, the Internet user accesses the storage server 130 through the Internet 120 using the user computer 110. The user computer 110 connected to the storage server 130 requests storage while transmitting a large amount of data, and the storage server 130 stores the received large amount of data in the storage space 140. In addition, the storage server 130 transmits a large amount of data stored in the storage space 140 to the user computer 110 when a request is received from the user computer 110.

On the other hand, since these storage services mainly use the server (Server) and client (Client) method, the role of the server has been emphasized in a server-centric manner. However, the server and the client method has a disadvantage in that traffic is concentrated on the server. That is, as the number of clients increases, the load, bandwidth, storage capacity, etc. requested by the server increases, and in some cases, the client may not be able to access the server. Attempts have been made to address these shortcomings and continued to evolve, eventually leading to peer to peer (P2P).

P2P is a person-to-person file sharing technology and behavior on the Internet. Peer-to-peer is a technology and behavior that makes symmetrical interactions happening on the network, allowing all computers connected to the network to share data and peripherals in the same peer position.

Systems for P2P can be classified into three types: central control system, hierarchical system, and distributed system. Here, the central control system has a server in the center and operates in a cooperative relationship among a plurality of peers. In other words, the peer attempts to connect to a central server, obtains information on which peer the data is, and downloads the data from the target peer. The system provided by Napster is a representative example of a central control system. The hierarchical system is a system in which all or part of the control authority is delegated to the lower controller. In a hierarchical system, each peer forms a group around a controller higher than itself, and all peers in that group are controlled by the controllers in that group. In addition, a distributed system is a system that guarantees free connection between all peers without control. In other words, in a distributed system, communication between peers is complementary, so that each peer can receive data through another peer even if one peer is disconnected at one place. Freenet and Gnutella are examples of distributed systems.

Recently, the explosive increase in the use of mobile communication terminals such as cellular phones and personal digital assistants (PDAs) and the demand for mobile communication services are increasing. For this reason, various studies are being actively conducted to apply various services in the existing wired environment in the mobile communication environment. However, since the data size of multimedia content or various applications used in a wired environment is large, there is a limitation of storage space for using such a large amount of data in a mobile communication terminal. In particular, the usage environment of the mobile communication terminal is gradually developed in a form similar to the desktop computer, which means that most applications and data currently used in the desktop computer can be used in the mobile communication terminal. In view of these developments, if the storage space limitation of the mobile communication terminal is overcome, the range of application will be wider, and the economical efficiency of adding expensive memory to secure the storage space will be solved.

Therefore, while activating wireless storage services to overcome the limitations of storage space in a mobile communication environment, technologies and services are needed for interworking with wired environments and efficiently providing wireless storage services. It is not.

The internet 230 connects the mobile communication network 220 and the content provider 240 to relay data transmitted and received between each other.

3 is a block diagram schematically showing an MP2P system according to a preferred embodiment of the present invention.

The MP2P system 230 according to the preferred embodiment of the present invention includes a virtual peer providing server 310, a virtual peer unit 320, and a storage unit 330.

The virtual peer provision server 310 is implemented with a conventional network server. A network server is a computer system and computer that is connected to a subordinate device capable of communicating with other network servers through a computer network, such as a private intranet or the Internet, to receive a request to perform a task and perform a task to provide a result of the execution. It means software (network server program). However, in addition to such a network server program, it should be understood as a broad concept including a series of applications running on a network server and in some cases various databases built therein. Such a network server may be implemented using a network server program that is variously provided according to an operating system such as DOS, Windows, Linux, UNIX, or Macintosh.

In addition, the virtual peer providing server 310 generates a first virtual peer 322, which is a virtual peer to the first peer 210, at the request of the first peer 210, and creates the first virtual peer 322. The storage service is performed by receiving data from the first peer 210, transmitting the data to the storage unit 330, and storing the data. In addition, the virtual peer providing server 310 allocates the same IP (Internet Protocol) as the first peer 210 to the generated first virtual peer 322.

In the present invention, the virtual peer (first virtual peer 322, second virtual peer 324) is a virtual peer to enable peer (first peer 210, second peer 250) to perform P2P. As a virtual peer logically generated by the provisioning server 310, the peer stores data in the storage unit 330 using the virtual peer and performs P2P with each other. The first peer 210 cannot perform P2P with the second peer 250 because the first peer 210 is a wireless terminal that cannot maintain an on-line state as in the aforementioned home. In order to solve this problem, in the present invention, a virtual peer for the first peer 210, such as the first virtual peer 322, is always created on a wired end that is always online, thereby enabling the first peer 210 and the wired environment of the wireless environment. To perform P2P between the second peers 250.

The virtual peer unit 320 is a set of virtual peers generated by the virtual peer provision server 310 and logically implemented by the virtual peer provision server 310. The first virtual peer 322 and the second virtual peer 324 of the virtual peer unit 320 each have the same IP as the first peer 210 and the second peer 250, and are always online. The data is stored in the storage unit 330 under the control of the first peer 210 and the second peer 250, and the first peer 210 and the second peer are searched, requested, and received based on P2P. Transmit to 2 peer 250.

This series of tasks is accomplished using JXTA Endpoint Messages and JXTA Resolver Messages, which are based on the JXTA protocol. That is, between the first peer 210 or the second peer 250 and the first virtual peer 322 or the second virtual peer 324 using the JXTA endpoint message to request the storage of data or to retrieve the data. And notify the result. JXTA between the first virtual peer 322 or the second virtual peer 324 and a Rendezvous peer (not shown) for message delivery, or between the first virtual peer 322 and the second virtual peer 324. Request and send and receive data using resolver messages.

Here, the JXTA endpoint message is a message that determines a path to an endpoint between peers in a P2P network. That is, in P2P networks, a unique random characteristic requires a mechanism for delivering messages between peers along a path, and a message providing such a mechanism is a JXTA endpoint message. JXTA resolver messages are also messages that provide a generic form of request and response that one peer uses in a peer-to-peer network to communicate with another peer, and then send the message to another peer for processing after the peer retrieves it. It is used to receive a message from another peer that contains the result.

The storage unit 330 includes a storage server 332, a database 334, and a storage 336, and data from the first peer 210 and the second peer 250 under the control of the virtual peer unit 320. Receive and save.

The storage server 332 is implemented as a network server, such as the virtual peer providing server 310, and receives data from the first peer 210 and the second peer 250 by receiving a control signal from the virtual peer unit 320. The received data is analyzed to generate information related to data such as file information, file size information, directory information of a stored file, file owner information, and the like, and store the data in the database 334. The file is stored in storage 336.

Here, the database 334 and the storage 336 refer to a data structure implemented in a storage space of a computer system using a database management system (DBMS) program, and search, delete, edit, and add data. It means a data storage type that can freely perform. Such a database uses a relational database management system (RDBMS) such as Oracle, Informix, Sybase, Microsoft Structured Query Language (MS SQL) or DB2 for the purpose of the present invention. It can be implemented to suit the needs and has appropriate fields or elements to perform functions such as storing, searching, deleting, editing and adding data.

In the present invention, the storage server 332 forms a directory for each virtual peer to store data, and stores information related to the data by classification such as file information, file size, file directory information, file owner, and the like. In addition, the storage server 332 uses the information related to the content stored in the database 334 to provide a search result for the data search request of the virtual peer unit 320 and, upon receiving a request to transmit specific data, to the storage 336. The stored corresponding data is transmitted to the virtual peer unit 320.

4 is a flowchart illustrating a data storage method in a wired / wireless integrated storage service providing method using P2P according to an exemplary embodiment of the present invention.

The first peer 210 temporarily or semi-permanently accesses a large amount of data to the MP2P system 230 using the storage JXTA application (S410). The first peer 210 connects to the MP2P system 230 using the mobile communication network 220, and the second peer 250 connects to the MP2P system 230 through the Internet 240. Here, the storage JXTA application is manufactured for mobile communication and wired communication, so that the first peer 210 uses the mobile communication storage JXTA application and the second peer 250 uses the wired communication storage JXTA application to the MP2P system 230. Connect.

The peer connected to the MP2P system 230 logs in to the storage service peer group using an authentication function provided by the storage JXTA application (S420). A peer must log in to a storage service peer group to use a wired / wireless unified storage service using P2P according to a preferred embodiment of the present invention. To this end, the storage JXTA application allows a peer to connect to the MP2P system 230 and a peer that connects to the MP2P system 230, that is, the first peer 210 or the second peer 250 and the MP2P system although not shown in FIG. A storage service peer group is formed between one or more peers (not shown) connected to the 230 or between the first peer 210 and the second peer 250 and a login procedure is performed according to a predetermined algorithm.

The first peer 210 logged into the storage service peer group may use the wired / wireless integrated storage service using P2P. The first peer 210 requests storage by transmitting data to the MP2P system 230 (S430). The MP2P system 230 that is requested to store data from the first peer 210 generates the first virtual peer 322 by using the virtual peer providing server 310 (S440). As described with reference to FIG. 3, the first virtual peer 322 is a logically created virtual peer having the same IP as the first peer 210, and is always online in the MP2P system 230. P2P is performed with the second virtual peer 324 with the same qualification.

The first virtual peer 322 transmits the data received from the first peer 210 to the storage server 332 by the MP2P system 230 and controls the storage server 332 to store the data (S450). ). When the storage server 332 receives the data from the first virtual peer 322, the storage server 332 analyzes the received data and stores data such as file information, file size, directory information of the stored file, file owner, and the like. The relevant information is generated and stored in the database 334, and a file which is actual data is stored in the storage 336. In the present invention, the storage server 332 forms a directory for each virtual peer to store data, and stores information related to the data by classification such as file information, file size, file directory information, file owner, and the like.

5 is a flowchart illustrating a data search and download method in a wired / wireless integrated storage service providing method using P2P according to an exemplary embodiment of the present invention.

Since the procedure of steps S510 to S520 in which the first peer 210 accesses the MP2P system 230 to log in to the storage service peer group is the same as the procedure of steps S410 to S420 described with reference to FIG. 4, a detailed description thereof will be omitted. . In operation S520, the first peer 210 logging in to the storage service peer group transmits a query to the MP2P system 230 and requests a search for data (S530). After receiving the query, the MP2P system 230 generates a first virtual peer 322 using the virtual peer providing server 310 (S540). Since the method of generating the first virtual peer 322 by the MP2P system 230 is the same as described in operation S440 of FIG. 4, a detailed description thereof will be omitted. Here, the query refers to a search condition for searching for data according to the requested instructions. That is, the storage server 322 compares the character string included in the query with the character string included in the information about the data stored in the database 334 to determine whether the same character string exists and whether information matching the requested data is stored. Check whether or not.

The created first virtual peer 322 forwards the query to the storage server 332. The storage server 332 receiving the query from the first virtual peer 322 retrieves the requested data through the query (S550). In retrieving the requested data, the storage server 332 checks whether information corresponding to the requested data is stored from the information about the data stored in the database 334.

As a result of the search in step S550, the storage server 332 notifies the first virtual peer 322 of the search failure. The first virtual peer 322 notified of the search failure notifies the first peer 210 of the search failure (S552). In addition, the storage server 332 searches for the virtual peer (the second virtual peer 324 in FIG. 2) that stores the data requested by the first virtual peer 322 when the search is successful as a result of the search in step S550. Send a search result containing the information. Upon receiving the search result from the storage server 332, the first virtual peer 322 checks the information about the second virtual peer 324 included in the search result and transmits the data to the second virtual peer 324 based on P2P. A request for transmission of data is received from the second virtual peer 324 (S560).

The first virtual peer 322, which has received data from the second virtual peer 324, transmits the received data to the first peer 210 using the mobile communication network 220, and the first peer 210 receives the first data. 1 Receive data from virtual peer 322.
