Description

PEER TO PEER SUPPORTING APPARATUS AND PEER TO PEER SUPPORTING METHOD
The present invention relates to a peer to peer (P2P) technology, and more particularly, to a P2P supporting apparatus and a P2P supporting method.
For terminal-to-terminal data transmission, a cloud scheme in which a transmitting terminal uploads a file to a server and a receiving terminal downloads the file from the server may be used. In such a scheme, upload and download speeds may depend on the positioning of the transmitting and receiving terminal or a network condition and such a scheme is vulnerable to security breaches and there are a lot of costs in constructing the server and a line.
In order to solve the problem an end-to-end connection, that is a P2P transmission technology, is required. According to the P2P transmission technology, since data is directly transmitted and received between terminals, the file need not be uploaded to or downloaded from the server. However, since a delay time for the P2P connection is lengthened due to an influence of gradually diversified network environments, there is a problem in which stable transmission is difficult.
The present invention has been made in an effort to provide a P2P supporting apparatus and a P2P supporting method.
An exemplary embodiment of the present invention provides a P2P supporting method of a P2P supporting apparatus including: receiving from a transmitting terminal a P2P request message including information on the transmitting terminal and information on a receiving terminal; selecting a relay node server positioned between the transmitting terminal and the receiving terminal; and transmitting a P2P response message including information on the selected relay node server to the transmitting terminal.
The relay node server may be selected by considering at least one of positions among the transmitting terminal, the receiving terminal, the relay node server, and a transmission speed of the relay node server.
Information on the transmission speed of the relay node server may be extracted by using information collected from each relay node server in advance.
The information collected in advance may include at least one of load information of each relay node server for a predetermined time, whether another server accessing each relay node server is present for a predetermined time, and information on an Internet service provider (ISP) supporting each relay node server.
Another exemplary embodiment of the present invention provides a P2P supporting apparatus including: a receiving unit receiving from a transmitting terminal a P2P request message including information on the transmitting terminal and information on a receiving terminal; a selecting unit selecting a relay node server positioned between the transmitting terminal and the receiving terminal; and a transmitting unit transmitting a P2P response message including information on the selected relay node server to the transmitting terminal.
Yet another exemplary embodiment of the present invention provides a P2P supporting system including: a transmitting terminal transmitting data to a receiving terminal through P2P; a relay node server relaying the data transmitted from the transmitting terminal to the receiving terminal; and a P2P supporting apparatus receiving from the transmitting terminal a P2P request message including information on the transmitting terminal and information on the receiving terminal, selecting the relay node server positioned between the transmitting terminal and the receiving terminal, and transmitting a P2P response message including information on the selected relay node server to the transmitting terminal.
The relay node server may not store the data transmitted from the transmitting terminal to the receiving terminal.
According to exemplary embodiments of the present invention, data can be transmitted at a stable speed through a terminal-to-terminal direct connection. As a result, a server and a line need not separately be constructed for uploading and downloading a file and there is no concern of being exposed to risk in case the server is comprised in a hacking attack.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which like reference numerals refer to like or similar elements regardless of reference numerals and a duplicated description thereof will be omitted.
FIG. 1 is a block diagram illustrating a peer to peer (P2P) supporting system according to an exemplary embodiment of the present invention.
Referring to FIG. 1, the P2P supporting system 10 includes a transmitting terminal 100, a P2P supporting apparatus 200, a plurality of relay node servers 300, and a receiving terminal 400.
The transmitting terminal 100 and the receiving terminal 400 may be a portable terminal, a tablet PC, and the like, which have a wireless communication function and a wireless Internet function. The transmitting terminal 100 transmits data to the receiving terminal 400 through peer to peer (P2P).
To this end, the P2P supporting apparatus 200 receives a P2P request message including information on the transmitting terminal 100 and information on the receiving terminal 400 from the transmitting terminal 100, selects the relay node server 300 positioned between the transmitting terminal 100 and the receiving terminal 400, and transmits a P2P response message including information on the selected relay node server 300 to the transmitting terminal 100.
The relay node server 300 selected by the P2P supporting apparatus 200 among the plurality of relay node servers 300 relays data transmission and reception between the transmitting terminal 100 and the receiving terminal 400. In this case, the relay node server 300 does not store the data transmitted from the transmitting terminal 100 to the receiving terminal 400.
FIG. 2 is a block diagram of a P2P supporting apparatus according to an exemplary embodiment of the present invention.
Referring to FIG. 2, the P2P supporting apparatus 200 includes a receiving unit 210, a selecting unit 220, a storing unit 230, and a transmitting unit 240.
The receiving unit 210 receives the P2P request message including the information on the transmitting terminal 100 and the information on the receiving terminal 400 from the transmitting terminal 100. Herein, the transmitting terminal 100 is a terminal that is intended to transmit data through P2P and the receiving terminal 400 is a target terminal that the transmitting terminal 100 intends to transmit data through P2P. The information on the transmitting terminal 100 and the information on the receiving terminal 400 may include identification information of the transmitting terminal 100 and identification information of the receiving terminal 400, respectively. The identification information of the transmitting terminal 100 and the identification information of the receiving terminal 400 may include identifications (ID) uniquely allocated to the transmitting terminal 100 and the receiving terminal 400, respectively. The IDs of the transmitting terminal 100 and the receiving terminal 400 may be allocated by the P2P supporting apparatus.
The selecting unit 220 selects the relay node server 300 that will relay P2P transmission of the transmitting terminal 100 based on the information on the transmitting terminal 100 and the information on the receiving terminal 200. In this case, the selecting unit 200 may select the relay node server 300 by considering positions among the transmitting terminal 100, the receiving terminal 200, and the relay node server 300. For example, the selecting unit 220 may select the relay node server 300 positioned on a path between the transmitting terminal 100 and the receiving terminal 400.
The selecting unit 220 may further select the relay node server 300 by further considering a transmission speed of the relay node server 300.
For example, the selecting unit 400 may select a plurality of candidate relay node servers by considering the positions among the transmitting terminal 100, the receiving terminal 200, and the relay node server 300 and select a relay node server having a highest transmission speed among the plurality of candidate relay node servers.
Alternatively, the selecting unit 220 may set distances up to the transmitting terminal 100, the relay node server 400, and the receiving terminal 400 as one variable D, set the transmission speed of the relay node server as another variable V, and select the relay node server by applying weighted values to both variables, respectively. Table 1 shows one example in which the selecting unit 220 selects the relay node server 400. Herein, it is assumed that as a distance degree D is small, a distance from the transmitting terminal to the receiving terminal through the relay node server is short and as a speed degree V is small, the transmission speed of the relay node server is high. In addition, it is assumed that each of weighted values of the distance degree D and the speed degree V is 0.5.
Table 1
Relay node sever No. Distance degree D Speed degree V Final degree
1 1 3 2
2 2 1 1.5
3 3 2 2.5
Referring to Table 1, it can be seen that the distance from the transmitting terminal to the receiving terminal through the relay node server is shortest in relay node server 1, but relay node server 2 is selected by further considering the transmission speed.
To this end, the storing unit 230 may store identification information and positional information for each terminal, identification information, positional information, transmission speed information for each relay node server in advance.
The positional information for each terminal may be statistical data extracted by using a plurality of pieces of Internet protocol (IP) information collected from a terminal which is moving. Herein, the statistical data may be estimated positional information for each time zone which is extracted from latitudinal and longitudinal information from each IPs information and temporal information when the IP information is collected. Herein, the IP information may be from a fixed router accessed by the terminal which is moving.
The transmission speed information for each relay node server may be statistical data extracted by using information collected from the relay node server in advance. Herein, the information collected from the relay node server in advance may include at least one of load information of each relay node server for a predetermined time, whether another server accessing each relay node server is present for a predetermined time, and a type of Internet service provider (ISP) supporting each relay node server. It may be estimated that as a load of the relay node server is smaller, the number of other servers accessing the relay node server is smaller, and the speed of the ISP supporting the relay node server is higher, the relay node server has a higher transmission speed.
When the selecting unit 220 selects the relay node server 300, the transmitting unit 240 of the P2P supporting apparatus 200 transmits the P2P response message including the information on the selected relay node server 300 to the transmitting terminal 100. Herein, the information on the relay node server 300 may include the identification information of the relay node server 300.
FIG. 3 is a flowchart illustrating a P2P supporting method of a P2P supporting system according to another exemplary embodiment of the present invention.
Referring to FIG. 3, when the transmitting terminal 100 intends to transmit the data to the receiving terminal 400 through P2P, the transmitting terminal 100 transmits the P2P request message including the information on the transmitting terminal 100 and the information on the receiving terminal 400 to the P2P supporting apparatus 200 (S300).
The P2P supporting apparatus 200 selects the relay node server 300 positioned between the transmitting terminal 100 and the receiving terminal 200 (S310). In this case, the relay node server 300 may be selected by considering the positions among the transmitting terminal 100, the receiving terminal 400, and the relay node server 300 and the transmission speed of the relay node server 300. In this case, the information on the transmission speed of the relay node server 300 may be extracted by using the information collected from each relay node server 300 in advance. Herein, the information collected in advance may include at least one of the load information of each relay node server for a predetermined time, whether another server accessing each relay node server is present for a predetermined time, and information on the Internet service provider (ISP) supporting each relay node server.
The P2P supporting apparatus 200 transmits the P2P response message including the information on the selected relay node server 300 to the transmitting terminal 100 (S320). Herein, the information on the relay node server 300 may include the identification information of the relay node server 300.
The transmitting terminal 100 that receives the information on the selected relay node server 300 from the P2P supporting apparatus 200 transmits the data to the receiving terminal 400 through the selected relay node server 300 through P2P(S330). In this case, the relay node server 300 just transmits the data transmitted from the transmitting terminal 100 to the receiving terminal 400 and does not store corresponding data.
FIG. 4 illustrates an example in which the P2P supporting apparatus selects a relay node server according to the exemplary embodiment of the present invention.
Referring to FIG. 4, the P2P supporting apparatus 200 may select a candidate relay node server of which a distance from the transmitting terminal 100 to the receiving terminal 400 through the relay node server 300 is shorter among the plurality of relay node servers 300 positioned between the transmitting terminal 100 and the receiving terminal 400. Herein, it is assumed that three candidate relay node servers (relay node server 1, relay node server 2, and relay node server 3) are selected, another server has already accessed relay node server 2, and relay node server 1 and relay node server 2 receive a support from a 3G mode ISP, but relay node server 3 receives a support from an LTE-mode ISP.
According to the exemplary embodiment of the present invention, although a path through relay node server 2 among the candidate relay node servers is shortest, relay node server 3 may be selected by considering the transmission speed of the relay node server.
Term "~unit" used in the exemplary embodiment means a software or hardware component such as a field-programmable gate array (FPGA) or ASIC, and "~unit" performs predetermined roles. However, "~unit" is not a meaning limited to software or hardware. "~unit" may be configured to be positioned in an addressable storage medium and configured to replay one or more processors. Therefore, as one example, 'unit' includes components such as software components, object oriented software components, class components, and task components, processes, functions, attributes, procedures, subroutines, segments of a program code, drivers, firmware, a microcode, a circuit, data, a database, data structures, tables, arrays, and variables. Functions provided in the components and 'units' may be joined as a smaller number of components and 'units' or further separated into additional components and 'units'. In addition, the components and "~units" may be implemented to replay one or more CPUs within a device or a security multimedia card.
The present invention has been described in detail with reference to the preferred embodiments. However, it will be appreciated by those skilled in the art that various modifications and changes of the present invention can be made within the scope without departing from the spirit and the area which are defined in the appended claims and their equivalents.
