System, method and program for P2P file transfer

1. A peer-to-peer (P2P) transfer method comprising:

receiving, at a server, first identification information of a search access point from a transmission client and a reception client;

in response to the transmission client and the reception client searching for a first access point as the same search access point or connects to the first access point being the same search access point, setting the first access point to a transfer path;

determining whether the first access point is blocked; and

matching whether the first access point is blocked with the first identification information and storing whether the first access point is blocked or not, the first identification information and a result of the matching in an accumulation database,

wherein the setting includes:

in response to the transmission client and the reception client searching for one or more search access points being the same, requesting connection of the transmission client and the reception client from a specific search access point providing a highest transfer speed, based on an upload speed of the transmission client and a download speed of the reception client.

2. The P2P transfer method of claim 1 , wherein the determining includes:

recognizing the first access point as being blocked, in response to a transfer time of a file sent from the transmission client exceeds a reference time, and

wherein that the first access point is blocked indicates blocking connection between clients through the first access point.

3. The P2P transfer method of claim 1 , wherein the determining includes:

checking the accumulation database to determine whether the first identification information corresponds to identification information matched as being blocked.

4. The P2P transfer method of claim 3 , further comprising:

selecting another transfer path except for a transfer path through the first access point in response to the first identification information corresponding to identification information matched as being blocked and stored in the accumulation database.

5. A peer-to-peer (P2P) transfer method comprising:

receiving, at a server, first identification information of a search access point from a transmission client and a reception client;

in response to the transmission client and the reception client searching for a first access point as the same search access point or connects to the first access point being the same search access point, setting the first access point to a transfer path;

determining whether the first access point is blocked by checking an accumulation database to determine whether the first identification information corresponds to identification information matched as being blocked;

matching whether the first access point is blocked with the first identification information and storing whether the first access point is blocked or not, the first identification information and a result of the matching in the accumulation database;

selecting another transfer path except for a transfer path through the first access point in response to the first identification information corresponding to identification information matched as being blocked and stored in the accumulation database,

wherein the selecting includes:

determining, at the server, whether a second access point except for the first access point is identically found at the transmission client and the reception client; and

requesting the transmission client to transfer a file to the reception client through the second access point, in response to the second access point being found, and

wherein the storing includes:

matching whether the second access point is blocked with second identification information and storing whether the second access point is blocked or not, the second identification information and a result of the matching associated with the second access point in the accumulation database.

6. The P2P transfer method of claim 1 , further comprising:

downgrading a priority upon setting a transfer path of the first access point.

7. The P2P transfer method of claim 1 , wherein the receiving includes:

receiving location information, through which the first identification information is recognized, from the transmission client or the reception client together; and

matching the first identification information with the location information, wherein the first identification information, the location information and the result of the matching the first identification information with the location information is stored in the accumulation database.

8. A peer-to-peer (P2P) transfer method comprising:

receiving, at a server, first identification information of a search access point from a transmission client and a reception client;

in response to the transmission client and the reception client searching for a first access point as the same search access point or connects to the first access point being the same search access point, setting the first access point to a transfer path;

determining whether the first access point is blocked;

matching whether the first access point is blocked with the first identification information and storing whether the first access point is blocked or not, the first identification information and a result of the matching in an accumulation database;

in response to a wireless communication function through an access point of the transmission client or the reception client being restricted, receiving respective location information recognized by the transmission client and the reception client, determining whether an access point covering a range, in which the respective location information is included, is present in the accumulation database, and activating the wireless communication function through the access point of the transmission client or the reception client in response to the access point being present.

9. The P2P transfer method of claim 1 , further comprising: receiving setting data associated with whether to perform a file transfer through the access point from the transmission client or the reception client.

10. A non-transitory computer-readable recording medium storing a program for a P2P transfer, and configured to be coupled to a computer being hardware, the program includes instructions to execute the method of claim 1 .
