Abstract: The invention is to solve the problem in that mutual communication between an IPv6-capble device and an IPv4-capble device has not been carried out in a system wherein the IPv6-capble device and the IPv4-capble device are mixed. An entry of a live list is retrieved when SM Device Annunciation is received from the IPv6-capble device, and a transmission IPv4 address is acquired from an IPv4 address pool if the entry is not found, thereby preparing translation rules so as to be stored in a translation rules storage section, while preparing an entry to be registered in the live list, whereby an IP address in a message is translated with reference to the translation rules. Further, a timestamp of the entry is updated every time when the SM Device Annunciation is received. Even if the address is contained in the message, the mutual communication between the IPv6-capble device and the IPv4-capble device can be carried out, and devices connected to the system can be controlled.

Abstract: Disclosed is an instrumentation control system, including: a first field device; and a second field device coupled to the first field device via a fieldbus. The first field device includes: a transmitting buffer to store data to be transmitted; a transmitter; and an inquiry processing section to cause the transmitter to retransmit the data stored in the transmitting buffer to the second field device in response to a request from the second field device. The second field device includes: a receiving buffer to store the data transmitted from the first field device; a checking section to determine whether the data stored in the receiving buffer is normal or not, and to make a data retransmission request to the first field device if the data stored in the receiving buffer is not normal; and a processing unit to perform predetermined processing based on the data which is determined to be normal.

Abstract: A gateway system for transiting communications at the boundary between networks includes a master gateway and at least one slave gateway. The master gateway processes a communication packet, updates state information based on the processing of the communication packet, and transmits the updated state information. The slave gateway receives state information transmitted from the master gateway, and stores the received state information as state information of the slave gateway. The slave gateway operates instead of the master gateway based on the stored state information.

Abstract: The objective of the present invention is to realize a structure which enables a client to utilize a translator without changing the DNS server specification, when a service targeted at general clients is provided. Therefore, the present invention is characterized by having an IPv6/IPv4 translator in which packets are translated reciprocally between IPv6 and IPv4 protocols, a configuration is employed so that a DNS query from a client reaches the translator DNS proxy using a dedicated domain effective as a specific DNS domain, and the above translator DNS proxy is able to be specified an operation by entering a defined character string in FQDN. While the present invention is also characterized by the fact that the above-described client specifies at least either an IPv6-based address or an IPv4-based address in FDQN as a desired address and the client also specifies at least either a translated address or an un-translated address as an address for the returning response.

Abstract: To prevent circuit elements of a semiconductor circuit from being erroneously operated, a simulation of operations of the circuit elements is performed when the designed semiconductor circuit is designed. In this simulation, an event (or a change of a signal value) is initially given to each of a plurality of external input pins of the designed semiconductor circuit, and the event of each external input pin is serially propagated circuit elements serially connected with each other with the passage of time. Therefore, an event occurs at a time in each circuit element. A clock skew between events of each pair of circuit elements is analyzed according to connection information and delay information of the circuit elements, and external input pin information of each external input pin is attached to the events occurring in the circuit elements in which the event of the external input pin is propagated.
