NODE DEVICE, COMMUNICATION NETWORK HAVING PLURAL NODE DEVICES AND THEIR CONTROLLING METHOD

摘要

PROBLEM TO BE SOLVED: To efficiently perform communication by transmitting plural packets to a terminal device in the order being different from the receiving order of plural received packets when a destination is a terminal device connected to a node device. SOLUTION: Header converting parts 171 to 178 and packet rearranging parts 161 to 168 are added to a conventional node device. The parts 171 to 178 have a function adding a connection number corresponding to the receiving connection of a destination terminal and a sequential number showing a transmission sequence together with the address of a node device and the address of the destination terminal to the header information of a packet transmitted from a terminal. The parts 161 to 168 have a function which rearranges packets separated by each separation inserting part 121 to 128 in every connection in the transmitted order based on a connection number being the header information and a sequential number. Thus, it is possible to perform efficient communication.
