Disclosed is a relay apparatus for forwarding a received multicast frame to a communication apparatus at a specified communication rate. The relay apparatus converts the received multicast frame to the corresponding unicast frame, sets a relatively higher communication rate than the specified communication rate, and forwards the converted unicast frame to the communication apparatus at the relatively higher communication rate. The relay apparatus determines whether or not the availability of the converted and forwarded unicast frame by an application is ascertained based on a condition, and prohibits conversion to the unicast frame when the availability is negated. This configuration enhances the user's convenience in the relay technique of converting multicast frames to unicast frames and forwarding the converted unicast frames.
