Abstract: A relay apparatus for relaying communication between a plurality of wireless terminals and a wired network includes a priority data recording part for recording communication identification data and required bandwidth data, a priority control part for relaying, by priority, the communication recorded in the priority data recording part, a request receiving part for receiving communication identification data and multimedia type data, a selecting part for selecting a multimedia type to be relayed by priority, an updating part for additionally recording data that represents a bandwidth required for relaying a stream of the selected multimedia type and the communication identification data, and a responding part for transmitting a response. The selecting part selects the multimedia type so that a sum of bandwidths represented by the required bandwidth data does not exceed a predetermined upper limit value.
