Abstract
Official abstract text for this publication.
A data packet routing system is provided wherein: at least one terminal belonging to a private IPv4 network is connected to a gateway itself connected to an IPv6 network; at least one interface device at the interface between said IPv6 network and a public IPv4 network implements a translation function comprising exchanging a private IPv4 address with a public IPv4 address. The gateway allocates to the terminal an IPv6 address by providing an IPv6 prefix with the private IPv4 address of the terminal in its private IPv4 network; said gateway verifying whether IPv4 address conflict exists, and if IPv4 it does exist, for replacing said private IPv4 address locally with a substitute private IPv4 address. A method is provided that routes an IPv4 data packet sent by a source terminal belonging to a first IPv4 domain via an IPv6 domain to a destination terminal belonging to a second IPv4 domain.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of routing an IPv4 data packet sent by a source terminal belonging to a first IPv4 domain, via an IPv6 domain, to a destination terminal belonging to a second IPv4 domain, said second IPv4 domain being private, said method comprising, on reception of said IPv4 data packet from said source terminal: constructing an IPv6 destination address; encapsulating the IPv4 data packet in an IPv6 data packet carrying said IPv6 destination address; and…
