Abstract:     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.

First Claim:
Show all 8 claims
What is claimed is:     1. A translator connected to a network, comprising:
  • a receiver which receives a packet of a first internet protocol (IP) packet sent from a host which is identified by an IP address of a first class and a packet of a second IP sent from a host which is identified by an IP address of a second class;
  • an IP packet translator responsive to reception of the second IP packet by said receiver, for generating a first IP packet having data included in the second IP packet, and responsive to reception of the first IP packet by said receiver, for generating a second IP packet having data included in the first IP packet;
  • a transmitter which transmits each of the first IP packet and the second IP packet generated by said IP packet translator to said network;
  • a storage which stores a plurality of addressees assigned to respective devices of interest using the first internet protocol; and
  • an address translator which sets any of a plurality of first IP addresses stored in said storage in a source storing field of said first IP packet when generating said first IP packet from the received second IP packet.
