Therefore, when server receives when receiving request from the file of user's terminal, if user's terminal request be Local Area Network (for example, the computer room) in by the management server manage the terminal inventory time, can search easily the other-end that is connected with user's terminal via Local Area Network.
At this moment, the terminal inventory that searches comprises the IP address of terminal, that is is used for the identification information of access terminal.
Search via after Local Area Network and the other-end that user's terminal is connected at step S1, in step S2 and S3, whether the other-end that searches in the network of inspection area has the file that user's terminal wish receives.
That is, when user's terminal wish receives file, at first will judge whether and can receive file from Local Area Network.By this, if receive file via Local Area Network, then user's terminal can be come download file at a terrific speed.
IPC is representative Local Area Network example, means the line between the processor in the Local Area Network.At this moment, need to have can be for the shortcut of two processor lines.For instance, IPC uses between two processors and shares at a high speed memory body as shortcut, and can be used as both connection modes in Local Area Network.
Compare with Wide Area Network, can ensure the data transmission bauds that is exceedingly fast because Local Area Network is stated in the situation of connection mode in the use, so file will receive via Local Area Network at first.
Thus, if judge that in step S2 and S3 terminal has the file destination that wish receives, then in step S4, make the documentary end of user's terminal tool from Local Area Network receive file control.
At this moment, can there be a plurality of terminals to have file among step S2 and the S3.That is, will select at least one terminal among step S2 and the S3.At this moment, will be controlled in setting P2P network between at least one terminal that is searched and the user's terminal among the step S4.
That is, because another terminal can receive in the block of a plurality of configuration files each, thus when searching the terminal that at least one searches, if use P2P connection mode then file transfer speed can speed much.
Thus, will between another terminal that searches and user's terminal, set the P2P network among the step S4, and control makes user's terminal receive file via the P2P network that sets with the P2P connection mode.By this, can in Local Area Network, obtain faster data transmission bauds.
According to the judged result among step S2 and the S3, if the documentary terminal of tool is not arranged, user's terminal arrives Wide Area Network with the transfer files request signals, and the terminal from external network receives file in step S5.That is user's terminal will receive file via outside Wide Area Network.At this moment, as mentioned above, user's terminal will receive file via itself and outside P2P network or the line of downloading server.
