摘要：
The present invention is a network layer protocol used for free-space optical transmission utilizing an LED or LD as a light source. In order to connect to a device, the network layer issues a connection request command (LAP_con_req2) to a lower layer when the network layer has received a connection request command (LM_con_req1) from an upper layer. Furthermore, when the network layer has received a connection confirmation command reception notification (LAP_con_conf1) from the lower layer, the network layer issues a connection confirmation command reception notification (LM_con_conf2) to the upper layer without issuing a data transfer request command to the lower layer. Accordingly, the invention provides a network layer protocol with which time for a connection or disconnection is reduced.
