Abstract

When communication data is delivered, the communication data can be distributed to each terminal without loss even if a failure occurs during communication data delivery or a data distribution terminal is interrupted, while ensuring the sequentiality of the communication data. A sender terminal transmits, to a data distribution terminal, communication data to be delivered to a receiver terminal. The receiver terminal holds information of both the data delivery terminal and a data delivery backup terminal and receives the communication data from the data delivery terminal or the data delivery backup terminal. The data delivery terminal receives the communication data transmitted from the sender terminal, copies the communication data into the data delivery backup terminal, and transfers the communication data to the receiver terminal. The data delivery backup terminal performs error checking on a data transfer process in the data delivery terminal and, if an error is detected, transfers the communication data temporarily stored in a retransmission buffer to the receiver terminal.
