摘要： In an apparatus, there are provided an IP transmitting and receiving unit for transmitting and receiving an IPv4 packet and an IPv6 packet; an IP header converting unit for performing a mutual conversion of the IPv4 packet and the IPv6 packet by an IP header conversion; a DNS substituting unit for receiving a domain information capturing request sent from an IPv4 terminal or an IPv6 terminal and substituting its process; an IPv4 address capturing unit for capturing an IPv4 address from a DHCP server; and an IP address conversion information holding unit for holding an IPv6 address of the IPv6 terminal and the IPv4 address captured by the IPv4 address capturing unit in correspondence to each other. Thus, a communication with the IPv4 terminal can be executed without preliminarily fixedly allocating the IPv4 address to the IPv6 terminal.

摘要： A packet communication method and a packet communication system capable of making an IPv4-compatible application operating on an information processing apparatus communicate with another information processing apparatus connected to an IPv6 network without using an address translation router. In the information processing apparatus connected to the IPv6 network incorporates, an IPv4-to-IPv6 protocol conversion control function is incorporated in a LAN driver. A protocol conversion control module receives an IPv4 packet from a protocol control module. When a send destination IPv4 address contained in a header of the packet is registered in an address translation table incorporated in the protocol conversion control module, an IPv6 address is generated to be sent onto a LAN. Unless the send destination IPv4 address contained in the packet header is registered in the address translation table incorporated in the protocol conversion control module, the IPv4 packet as received is intactly sent onto the LAN.

摘要： A translator for coupling a first network such as an internet protocol version 4 (IPv4) and a second network such as an internet protocol version 6 (IPv6) having different addressing architectures for IP addresses due to a difference in version or the like so as not to exhaust the IP addresses of one of the two networks, a network system using the translator, and a network coupling method therefor are provided. When a packet is transferred from the IPv6 network to the IPv4 network, the translator assigns any of a plurality of previously prepared IPv4 addresses to an IPv6 address stored in a source storing field of the IPv6 packet. The assigned address is stored in a source storing field of an IPv4 packet. A packet translation unit is provided for assigning the foregoing IPv6 address to an IPv4 address stored in a destination storing field of the IPv4 packet, when a packet is transferred from the IPv4 network to the IPv6 network, and for storing this address in a destination storing field of the IPv6 packet.

摘要： An internetworking apparatus for interconnecting a plurality of networks, having forwarding sections corresponding to interfaces of the networks, each including a processor for performing packet forwarding processing and a statistics unit for collecting processing time statistics of the processor. An adjusting section connected to all the forwarding sections through a bus instructs each processor to change a program to be executed thereby based on the processing time statistics reported by each processor so as to balance processing loads on the respective processors.

摘要： A display control system provided between a computer and a display device includes a plurality of display control LSI's for data transfer and also displays image data stored in a plurality of image memories having planes on the display device by controlling plane groups which include one or more planes. Each display control LSI includes an enable generator for generating a synchronization enabling signal in accordance with LSI designation information and an input/output buffer for outputting a synchronization signal in response to the enabling signal. A synchronization signal from one of the plurality of display control LSI's designated by the LSI designation information is supplied to the plurality of display control LSI's inclusive of the designated display control LSI through a signal line to allow the plurality of display control LSI's to operate with each other, thereby making it possible to produce and display data to be simultaneously on the display device.
