Abstract
An example network device includes one or more network interface cards and a control unit. The network interface cards are configured to send and receive messages with a first network operating in accordance with a first network-layer protocol and a second network operating in accordance with a second network-layer protocol and a control unit. The control unit is configured to receive a message via the one or more network interface cards, transform the message from conforming to a first transitioning protocol to conforming to a second transitioning protocol, and forward the message via the second network.
Claims21
A method comprising:
- receiving, with a network device, a message via a first network, wherein the message conforms to a first transitioning protocol, and wherein the network device couples the first network operating in accordance with a first network-layer protocol with a second network operating in accordance with a second network-layer protocol;
- transforming, with the network device, the message from conforming to the first transitioning protocol to conforming to a second transitioning protocol, wherein the first and second transitioning protocols are different transitioning protocols for transitioning between Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6), and wherein each of the first and second transitioning protocol use a different format for tunneling network packets of the first network-layer protocol over the second network operating in accordance with the second network-layer protocol;
- and
- forwarding, with the network device, the message via the second network.

A non-transitory computer-readable storage medium encoded with instructions for causing one or more programmable processors to:
- receive a message via a first network, message conforms to a first transitioning protocol, and wherein the first network operates in accordance with a first network-layer protocol;
- transform the message from conforming to the first transitioning protocol to conforming to a second transitioning protocol, wherein the first and second transitioning protocols are different transitioning protocols for transitioning between Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6), and wherein each of the first and second transitioning protocol use a different format for tunneling network packets of the first network-layer protocol over the second network operating in accordance with the second network-layer protocol;
- and
- forward the message via a second network, the second network operates in accordance with a second network-layer protocol.

A network device comprising:
- one or more network interface cards configured to send and receive messages with a first network operating in accordance with a first network-layer protocol and a second network operating in accordance with a second network-layer protocol;
- and
- a control unit configured to receive a message via the one or more network interface cards, transform the message from conforming to a first transitioning protocol to conforming to a second transitioning protocol, and forward the message via the second network, wherein the first and second transitioning protocols are different transitioning protocols for transitioning between Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6), and wherein each of the first and second transitioning protocol use a different format for tunneling network packets of the first network-layer protocol over the second network operating in accordance with the second network-layer protocol.
A method comprising:
- receiving, with a network device, a message via a first network, wherein the message conforms to a first transitioning protocol, and wherein the network device couples the first network operating in accordance with a first network-layer protocol with a second network operating in accordance with a second network-layer protocol;
- transforming, with the network device, the message from conforming to the first transitioning protocol to conforming to a second transitioning protocol, wherein the first and second transitioning protocols are different transitioning protocols for transitioning between Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6), wherein each of the first and second transitioning protocol use a different format for tunneling network packets of the first network-layer protocol over the second network operating in accordance with the second network-layer protocol, wherein the first transitioning protocol is either 1) a 6 to 4 network protocol or 2) a 6rd network protocol, and wherein the second transitioning protocol is the other one of the 6 to 4 network protocol and the 6rd network protocol;
- and
- forwarding, with the network device, the message via the second network.
