Abstract
Even in a network system including a transmission line of which dominant cause of delay is a transmission line delay, controlling communication speed of the network system as a whole efficiently and suppressing the delay is made possible.A communication data transmission equipment which performs sending and receiving of data with opposite transmission equipment connected via a long-distance optical fiber circuit, includes a data sending and receiving unit which, after sending a connection establishment request to the opposite transmission equipment, sends data before arrival of an acknowledgement reply, a circuit state monitoring unit which estimates data loss occurrence probability from data loss occurrence state in sending and receiving of data with the opposite transmission equipment or acquires data loss occurrence probability which the opposite transmission equipment estimated and a unit performing controls which, until the data loss occurrence probability exceeds a predetermined value, do not restrict a data size per each sending of data, and in case the data loss occurrence probability exceeds the predetermined value, reduce the data size per each sending of data according t…
