摘要： PROBLEM TO BE SOLVED: To provide a method and a device for preventing unauthorized connection to a network which have low costs and require low man-hours for introduction with respect to closed area communication within a LAN.
SOLUTION: It is discriminated whether unique information of a terminal included in an ARP request received from the terminal through the LAN is already registered or not, and the terminal is regarded as an unauthorized terminal to transmit a disturbing message showing duplication of unique information of the terminal when it is discriminated that it is not registered yet. The ARP request is an ARP request transmitted when connecting to the network or an ARP request by which the unauthorized terminal requests unique information to another terminal. The disturbing message comprises at least one of a disturbing reply wherein unique information of the unauthorized terminal is set in a transmission source address, and a disturbing request so that the unauthorized terminal is in a unique information duplicate state. It may be discriminated whether unique information of a terminal is already registered or not by an ARP reply returned in response to an ARP request which is successively transmitted to registered terminals. The unique information includes a MAC address or an IP address and includes a VLAN tag also.

摘要： PROBLEM TO BE SOLVED: To speed up data transmission in communication between two devices. SOLUTION: (1) Low-order FB transmits an REQ signal to an interface control part B. (2) When the control part B receives the REQ signal, it returns a bus use permission signal ACK signal to low-order FB and permits the use of a bus. (4) The control part B transmits the REQ signal to an interface control part A at the same time as (2). (3) When low-order FB receives the ACK signal, it transmits DATA to the control part B. The control part B accumulates the DATA in a FIFO buffer. (5) When the control part A receives the REQ signal, it returns the bus use permission signal ACK to the control part B and permits the use of the bus. (6) When the control part B receives the ACK signal form the control part A, it transmits DATA accumulated in the buffer without delay.
