Abstract
The present invention aims to realize a system and method of reliably performing multicast communication via a bandwidth-guaranteed network, and provides a multicast communication system for performing multicast communication via a bandwidth-guaranteed network, the system including: a multicast proxy response device added with a group address destination identifier; and a multicast client, wherein the multicast proxy response device transmits a session connection request to the group address destination identifier of the multicast proxy response device when starting reception, the multicast proxy response device which has received said session connection request transmits a session connection response to said multicast client, and the multicast client receives multicast data through a bandwidth secured in the bandwidth-guaranteed network by the session connection response.
