<p><P>PROBLEM TO BE SOLVED: To provide a multi-address packet transmission system and a multi-address packet reception system enabling a reception side to perform normal reception without making the reception side request the retransmission of abandoned multi-address packets even in the case that a part of the multi-address packets are abandoned. <P>SOLUTION: A radio LAN base station 100 multicasts the multi-address packets to which sequence numbers are attached to a LAN packet 300 for two or more times (301, 302). At the time of receiving the same multi-address packet for two or more times, a radio LAN terminal 230 abandons redundant multi-address packets and leaves only one multi-address packet. Since the multi-address packet is multicasted for two or more times, unless all the same multi-address packets are lost, the radio LAN terminal can receive the multi-address packet. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
