<p><P>PROBLEM TO BE SOLVED: To provide a method and device for wireless relay, as well as its computer program, capable of preventing a packet loss rate of the entire network system from being affected by a high packet loss rate at multicast transmission of wireless LAN. <P>SOLUTION: A wireless LAN relay device 1 receives an IP multicast packet from an audio motion picture multicast transmitter 2 through a wide area network 3. Then, it converts the IP multicast packet into an MAC unicast packet, and transmits the MAC unicast packet to terminals 4-1 to 4-2 that participate in an IP multicast group using wireless LAN. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
