DATA TRANSFER DEVICE, DATA TRANSFER METHOD, AND DATA TRANSFER SYSTEM

摘要

A data acquirer (101) acquires data from the other device and stores the data in a buffer (102). A communicator (103) transmits the data stored in the buffer (102) to a data collection server (20). A line state acquirer (104) acquires information on a line (line state data) and accumulates and stores the acquired line state data in a line state storer (105). A transmission data amount determiner (108) determines a data amount transmittable by one connection to the data collection server (20) based on the line state data stored in the line state storer (105). A transmission schedule generator (109) generates a transmission schedule for data based on a total amount of data stored in the buffer (102) and the data amount transmittable by one connection. The communicator (103) transmits data according to the transmission schedule.
