Data distribution management device and data distribution management method

摘要

A data distribution management device (10) is provided on a transmission route between a transmission device (C1) that requires a delivery acknowledgement corresponding to data transmitted and a receiving device (C2) in which a transmission delay in a circuit (2) is smaller than a transmission delay in a circuit (3), and comprises a transfer unit that transfers the data from the transmission device (C1) to the receiving device (C2), a returning unit that prepares a delivery acknowledgement corresponding to the data transferred and send the delivery acknowledgement to the transmission device. The data distribution management device (10) also comprises a SG distribution control section (16) that decides whether the data transmitted by the transmission device (C1) is a protocol dependent on transmission delays and that orchestrates the returning unit to prepare a delivery acknowledgement and send the delivery acknowledgement when it is decided that the data is the delay dependent protocol.
