PROBLEM TO BE SOLVED: To improve efficiency in link utilization by multiplexing flows, without incurring buffer overflow, in a packet transfer device which implements 1+1 protection to traffic that has a variable length and is received irregularly. SOLUTION: In a data transfer device, in a case where third data to which a third sequence number is given that is a sequence number next to a second sequence number are received from a first communication path before receiving second data to which the second sequence number is given, the received third data are stored in a buffer. In a case where the second data to which the second sequence number is given are received from a second communication path, the second data and the third data are sequentially transmitted. In a case where the third data to which the third sequence number is given are received from the second communication path before receiving the second data to which the second sequence number is given, the third data are transmitted. After the lapse of a predetermined waiting time, the third data are transmitted. COPYRIGHT: (C)2009,JPO&INPIT |
