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 routing apparatus has a plurality of routing units, connected by a first connecting mechanism. The plurality of routing units comprise a first routing unit, connected to at least one port, and a second routing unit, connected to an extended function processor. The first routing unit transmits a packet, received from the port, to another first routing unit and/or a second routing unit. The second routing unit transmits the packet, received from the first connecting mechanism, to the extended function processor.

An internetwork arrangement including: a prefix request unit for requesting an IPv6 address prefix from each of one or more first internetwork apparatuses; a prefix generation unit for generating a second prefix required to create an IPv6 address in the user apparatus utilizing a service, the second prefix having a length different from that of said IPv6 address prefix, on the basis of each of the one or more arbitrary IPv6 address prefixes, which differ for every service, given as notice by said one or more first internetwork apparatuses; and a prefix sending unit for giving notice of one or more generated second prefixes to the connected user apparatus utilizing said service.

摘要:
A first internetwork apparatus connected to a network retains a plurality of IPv6 address prefixes and gives notice of an arbitrary IPv6 address prefix to a second internetwork apparatus in response to a request from the second internetwork apparatus. A second internetwork apparatus requests an IPv6 address prefix from the first internetwork apparatus, and generates a second prefix required to create an IPv6 address in a user apparatus, on the basis of one or more IPv6 address prefixes given as notice by the first internetwork apparatus. The second internetwork apparatus gives notice of the generated second prefix to the user apparatus.
