4. A method for setting sessions, which is performed by a reception node on a network including a plurality of transmission nodes transmitting data, the reception node receiving the data, and a third node to which the reception node will transmit the data, the method comprising:
receiving at least some of the data through initial sessions;
calculating a number of additional sessions for receiving the data from the transmission node by using a transmission rate from the reception node to the third node and data transmission information between the plurality of transmission nodes and the reception node; and
setting additional sessions as many as the calculated number of additional sessions.
5. The method for setting sessions of claim 4 , wherein the calculating of the number of additional sessions for receiving the data is performed by further using at least one of usable transmission/reception bandwidth information of the reception node and the third node, transmission/reception quality information, and attribute information of the data.
6. A reception node on a network constituted by a plurality of nodes including a plurality of transmission nodes transmitting data and a reception node receiving the data, comprising:
a session setting unit setting sessions with the transmission node; and
a data transmitting/receiving unit transmitting or receiving data through the session set by the session setting unit,
wherein the data transmitting/receiving unit receives at least some of the data including attribute information of the data through initial sessions set by the session setting unit,
the reception node further includes an additional session calculating unit calculating a number of additional sessions for receiving the data by using the attribute information of the data received by the data transmitting/receiving unit and data transmission information between the plurality of transmission nodes and the reception node, and
the session setting unit sets additional sessions with the transmission node as many as the number of additional sessions, which is calculated by the additional session calculating unit.
7. The transmission/reception node of claim 6 , wherein the attribute information of the data is at least one of a size of the data, a file type of the data, and a service method of the data.
8. The transmission/reception node of claim 6 , wherein the calculating of the number of additional sessions for transmitting or receiving the data in the additional session is performed by further using at least one of usable transmission/reception bandwidth information of the transmission node and the reception node and transmission/reception quality information.
9. A reception node on a network including a plurality of transmission nodes transmitting data, the reception node receiving the data, and a third node to which the reception node will transmit the data, comprising:
a session setting unit setting sessions with the transmission node; and
a data transmitting/receiving unit transmitting or receiving data through the session set by the session setting unit,
wherein the data transmitting/receiving unit receives at least some of the data through initial sessions,
the reception node further includes an additional session calculating unit calculating a number of additional sessions for receiving the rest of the data from the transmission node by using a transmission rate to the third node and data transmission information between the plurality of transmission nodes and the reception node, and
the session setting unit sets additional sessions with the transmission node as many as the number of additional sessions, which is calculated by the additional session calculating unit.
10. The transmission/reception node of claim 9 , wherein the calculating of the number of additional sessions for transmitting or receiving the data in the additional session calculating unit is performed by further using at least one of usable transmission/reception bandwidth information of the reception node and the third node, transmission/reception quality information, and attribute information of the data.
