摘要

PROBLEM TO BE SOLVED: To provide a data distribution management device that prevents a transmission reception buffer from being overflowed, eliminates congestion on a channel with a large delay, reduces time required for re-transmission and maintains the reliability and high-speed performance of communication. SOLUTION: Each of the data distribution management devices 10, 20 is provided with a reception buffer 7 that temporarily stores data sent from a terminal C1, a transmission buffer 6, a distribution management table 1 that stores a reception window size of a terminal C2, and an SG distribution management section 16 regulates a transfer speed of data temporarily stored in the reception buffer 7 and the transmission buffer 6 corresponding to the received window size as its control.
