Abstract
A method of NAT64 translation includes discovering NAT64-Prefix by an IPv6 host, generating IPv4 connectivity by a customer-side translator (CLAT) device according to NAT64-Prefix, notifying the IPv4 connectivity to a private IPv4 (v4p) host, and notifying IPV4 header configuration to the v4p host by the CLAT device. The IPV4 header configuration includes a header length. The method further includes increasing a header length of the IPv4 header by the v4p host.
Claims17
A method of NAT64 translation comprising:
- discovering NAT64-Prefix by an IPv6 host;
- generating IPv4 connectivity by a customer-side translator (CLAT) device according to NAT64-Prefix;
- notifying the IPv4 connectivity to a private IPv4 (v4p) host;
- notifying IPv4 header configuration to the v4p host by the CLAT device, the IPv4 header configuration comprising a header length;
- and
- increasing the header length by the v4p host.

A method of NAT64 translation comprising:
- generating an IPv4 packet by a private IPv4 (v4p) host, the IPv4 packet comprising an IPv4 header with dummy options and a payload;
- sending the IPv4 packet from the v4p host to a customer-side translator (CLAT) device;
- translating the IPv4 header and the dummy option to an IPv6 header, by the CLAT device, to generate an IPv6 packet;
- and
- sending the IPv6 packet, by the CLAT device, to an IPv6 network.

A method of NAT64 translation comprising:
- generating an IPv4 packet by a private IPv4 (v4p) host, the IPv4 packet comprising an IPv4 header with dummy options and a payload;
- sending the IPv4 packet from the v4p host to the customer-side translator (CLAT) device;
- translating the IPv4 header and the dummy option to an IPv6 header and a fragmentation header to generate an IPv6 packet;
- and
- sending the IPv6 packet to an IPv6 network.
