In connection management by a conventional server apparatus using IDs, a client apparatus cannot know an attribute of a connection corresponding to an ID. A server apparatus (10) is an AV server apparatus that distributes content to a client apparatus requesting content data. A communication unit (11) receives a logical connection establishment request or a physical connection establishment request from the client apparatus. A content data distribution unit (14) establishes a physical connection for distributing the content data to the client apparatus, when the physical connection establishment request is received. A connection information management unit (15) establishes a logical connection, when the logical connection establishment request is received or as a result of the establishment of the physical connection. The connection information management unit (15) further generates an ID (connection ID) that corresponds to the logical connection and belongs to a value range associated with a logical connection category (type).
