Node device, packet control device, radio communication device, and transmission control method

摘要

A network system comprises (i) a node device (3) which comprises a reception unit (255) for receiving a first packet according to a first protocol, a transmission unit (250) for transmitting a second packet according to a second protocol, and a controller (252), (ii) a packet control device (4) connected to the node device (3), and (iii) an access point (5) connected to the packet control device (4). The controller is adapted to preparing a frame (84, 85) including a received first packet, creating a plurality of second packets by dividing the prepared frame, and adding to each of the second packets a concatenation flag as first control information that indicates whether or not the second packet includes a data fragment corresponding to a head or a tail of the frame.
