The transmitter has a request generating part for generating a connection request including data and commands required to connect the plurality of adjacent communication layers, and a request transmitting part for transmitting the connection request to the receiver. The receiver has a request receiving part for receiving the connection request from the transmitter, and a connection establishing pant for extracting the data and commands from the connection request and establishing, based on the extracted data and commands, the connections of the communication layers. In this way, the time required for establishing the connections can be shortened.

摘要： In a transmitter (2001), when generating a transmission frame having no limitation to a window size, a batch-transmission-end flag generating circuit (2004) and a sequence number generating circuit (2005) respectively adds a batch-transmission-end flag and a sequence number to the transmission frame. In a receiver, if an omission of a sequence number is detected as a result of analyzing sequence numbers of frames having received from the transmitter (2001), retransmission request is made when receiving a frame whose batch-transmission-end flag indicates the end. In this way, retransmission is possible in data transmission using UI frames, and the communication efficiency can be improved.

摘要： Provided is a communication system including a transmitter and a receiver which carry out communication by establishing connection of their plurality of communication layers. The transmitter generates a connection request containing a command and data required for connecting a number of contiguously adjacent layers among the plurality of communication layers and transmits the connection request to the receiver. The receiver receives a connection request containing a command and data required for connecting a number of contiguously adjacent layers among the plurality of communication layers, extracts the command and data from the connection request, and establishes connection for the plurality of communication layers based on the command and data. In this way, the time taken to establish connection is reduced. Therefore, even when the connection is cut off during the data exchange, the connection can be established again without taking much time, allowing quick recovery of data exchange.

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.

摘要： A transmitter apparatus 1 transmits transfer data having a predetermined amount to a receiver apparatus. The apparatus 1 includes: a data packet generating section 132 dividing the transfer data into multiple divisional data sets; an error detection/correction code adding section 133 adding an error detection code (error detection information) by which an error in the divisional data sets is detected to each of the divisional data sets; and a transmitter section 14 transmitting the multiple divisional data sets to which the error detection code is added all together. Thus, data transfer is very reliable. It takes less time to transfer data.
