摘要

An management system comprises: a transceiver unit which receives transmission terminal identification information of a plurality of transmission terminals used in transmission and receiving of content data; a relay device extraction unit (56b) which, on the basis of the received transmission terminal identification information, specifies relay device identification information of a relay device which a plurality of transmission terminals is respectably capable of using in common, among relay device identification information which is managed by a relay device selection management unit; and a selection unit (56c) which, among the specified relay device identification information, selects the relay device based on the relay device identification information, and among which acceptability information which is managed by the relay device management unit denotes acceptability, as a relay device which relays the transmission and receiving of the content data.
