Abstract
A network gateway device, comprises a tactical data link interface circuit to receive a message from a tactical data link unit in a tactical data link network, the tactical data link unit associated with a unique identifier within the tactical data link network; a message transformation circuit to: extract the unique identifier from the message; and build an Internet Protocol packet using a source address based on the unique identifier; and an Internet Protocol interface circuit to process the Internet Protocol packet toward a destination.
Claims15
A method comprising:
- receiving by a network gateway device, a message from a tactical data link unit in a tactical data link network, the tactical data link unit associated with a unique identifier within the tactical data link network and lacking a preassigned Internet Protocol address;
- identifying, by the network gateway device, a message format from a message header of the message;
- based on the message format, extracting, by the network gateway device, a portion of the message representing at least a portion of the unique identifier;
- building, by the network gateway device, an Internet Protocol packet that includes a source address field in a header portion, and generating a value of the source address field that is based on a combination of the unique identifier and an identifier of the tactical data link network;
- and
- sending, by the network gateway device, the Internet Protocol packet toward a destination over an Internet-Protocol network, wherein the message from the tactical data link is incompatible with the Internet-Protocol network.
A network gateway device, comprising:
- a tactical data link interface circuit to receive a message from a tactical data link unit in a tactical data link network, the tactical data link unit associated with a unique identifier within the tactical data link network and lacking a preassigned Internet Protocol address;
- a message transformation circuit to:
- identify a message format from a message header of the message;
- based on the message format, extract a portion of the message representing at least a portion of the unique identifier;
- build an Internet Protocol packet that includes a source address field in a header portion, and generating a value of the source address field that is based on a combination of the unique identifier and an identifier of the tactical data link network;
- and
- an Internet Protocol interface circuit to send the Internet Protocol packet toward a destination over an Internet-Protocol network, wherein the message from the tactical data link is incompatible with the Internet-Protocol network.
A non-transitory computer-readable medium including instructions, which when executed by a computer, cause the computer to perform the operations comprising:
- receiving, at a network gateway device, a message from a tactical data link unit in a tactical data link network, the tactical data link unit associated with a unique identifier within the tactical data link network and lacking a preassigned Internet Protocol address;
- identifying a message format from a message header of the message;
- based on the message format, extracting a portion of the message representing at least a portion of the unique identifier;
- building an Internet Protocol packet that includes a source address field in a header portion, and generating a value of the source address field that is based on a combination of the unique identifier and an identifier of the tactical data link network;
- and
- sending the Internet Protocol packet toward a destination over an Internet-Protocol network, wherein the message from the tactical data link is incompatible with the Internet-Protocol network.
