System and method for transferring data over a network

(-- 57) summary -- the method for transmitting the data aggregate through a network is offered by monitoring an actual network bandwidth use level. This method includes two enforcement forms using a different algorithm. With the 1st enforcement form, this method identifies the maximum by which the actual usage rate was monitored, and calculates the threshold level of a usage rate as an interrelative element of the maximum in which the usage rate was monitored. A threshold level expresses the level which can transmit or download a set of the data of a software update etc. Through a network, without barring other network activities in a network interface, if less than it. When the actual level of the usage rate is less than the threshold level, at least 1 portion of data, i. E. , a segment, is received through a network. With the 2nd enforcement form, this method identifies the maximum by which the actual usage rate was monitored, and calculates the size of the data block which should be transmitted as an interrelative element of the level maximum in which the usage rate was monitored. A data block expresses the segment of a set of the data of a software update etc. Which can be transmitted or downloaded through a network without barring other network activities in a network interface.
