WIRELESS COMMUNICATION APPARATUS, WIRELESS NETWORK SYSTEM, DATA TRANSFER METHOD, AND RECORDING MEDIUM

摘要

A WMMR (301) is used as a wireless relay node in a wireless network connected to a backbone network including a multicast data packet distribution source. A route control unit (N03) establishes a multicast data packet transfer route based on unicast routes by making reference to an SWGT (20) based on received route control information and adding an entry to a multicast routing table (MRT) (10). A transfer control unit (N04) makes reference to the MRT (10) and makes a transfer to a directly connected transfer destination along the established multicast data packet transfer route by unicasting capable arrival confirmation and retransmission control as a transmission scheme in the data link layer.
