DEVICE, SYSTEM AND METHOD FOR AUTOMATIC IPV4 PROVISIONING IN A LOCAL AREA NETWORK CONNECTED TO AN IPV6 NETWORK

摘要

A protocol tunneling device for supporting communication between a local IPV4 data source comprising a network layer identified by a data source IPv4 address and located on a local area network and a remote IPv4 data sink, the data source communicating using IPv4 protocol data packets with the data sink via a communications path comprising the protocol tunneling device, an IPv6 router and a tunneling end point, the protocol tunneling device, router and tunneling end point communicating using an IPv6 protocol, the tunneling end point and the data sink communicating using the IPv4 protocol, and the protocol tunneling device and the data source communicating using the IPv4 protocol.
