Abstract
Data communication method and system for transmitting a large amount of data via a network such as LAN to which a plurality of stations or terminals are connected, through a simplified processing procedure with high reliability and high efficiency while suppressing influence to other communications. The large amount of data is transmitted from a sender station to a plurality of receiver stations by utilizing a connectionless communication service, while inter-station reception acknowledging/retransmitting processings are performed by using a connection-oriented communication service. The large amount of data to be transmitted is divided into a plurality of blocks, and inter-block delay time is set on the basis of station status factors such as a permissible load increase rate of the CPU of the individual stations.
