Abstract:
1. A communication apparatus, comprising: a wireless station conversion determiner that determines, on reception of a unicast frame, whether the received unicast frame is a converted unicast frame from a multicast frame, based on conversion information attached to the unicast frame by a relay apparatus configured to forward the unicast frame; a wireless station application determiner that determines whether the converted unicast frame is transferrable to an application installed in the communication apparatus to utilize a multicast frame; and a wireless station reconverter that reconverts, when the conversion determiner determines that the received unicast frame is the converted unicast frame and the wireless station application determiner determines that the converted unicast frame is not transferrable to the application, the received unicast frame to a multicast frame and transfers the reconverted multicast frame to the application wherein the wireless station reconverter does not perform the reconversion when the wireless station application determiner determines that the unicast frame is transferable to the application.
