Concurrent data transfer involving two or more transport layer protocols over a single one-way data link
View Patent ↗A data transfer application for concurrent transfer of data streams based on two or more transport layer protocols via a single one-way data link. The present invention provides a great degree of routing flexibility by providing seamless network connectivity under a plurality of transport layer protocols, such as TCP and UDP, between multiple source and destination platforms over a single one-way data link.
1. A system for transferring data across a single one-way link, comprising:
a single one-way link having an input and an output, the single one-way link adapted to transfer data only from the input to the output and to prevent any signal from passing from the output to the input;
a data transmitter coupled to the input of the single one-way link and for receiving the data in two or more different types of transport layer protocols from source platforms, replacing an Internet Protocol (IP) information of the source platforms with a channel number, and transmitting the data in the two or more different types of transport layer protocols across the one-way link concurrently; and
a data receiver coupled to the output of the single one-way link and for receiving the data in the two or more different types of transport layer protocols from the one-way link and forwarding the data in the two or more different types of transport layer protocols to destination platforms,
wherein an IP information of the destination platforms remains undisclosed at the source platforms.
2. The system of claim 1 , wherein each of the data transmitter and the data receiver hosts sockets corresponding to the two or more different types of transport layer protocols to receive the data in the two or more different types of transport layer protocols.
3. The system of claim 2 , wherein the sockets comprise one or more UDP ports and one or more TCP ports.
4. The system of claim 1 , wherein the two or more different types of transport layer protocols comprise UDP and TCP.
5. A one-way data transfer system, comprising
two or more source platforms;
two or more destination platforms;
a single one-way link for unidirectional transfer, the single one-way link having an input and an output, the single one-way link adapted to transfer data only from the input to the output and to prevent any signal from passing from the output to the input;
a data transmitter coupled to the input of the single one-way link and for receiving the data in two or more different types of transport layer protocols from the two or more source platforms, replacing an Internet Protocol (IP) information of the source platforms with a channel number, and transmitting the data in the two or more different types of transport layer protocols across the one-way link concurrently; and
a data receiver coupled to the output of the single one-way link and for receiving the data in the two or more different types of transport layer protocols from the one-way link and forwarding the data in the two or more different types of transport layer protocols to the two or more destination platforms,
wherein an IP information of the destination platforms remains undisclosed at the source platforms.
6. The one-way data transfer system of claim 5 , wherein each of the data transmitter and the data receiver hosts sockets corresponding to the two or more different types of transport layer protocols to receive the data in the two or more different types of transport layer protocols.
7. The one-way data transfer system of claim 6 , wherein the sockets comprise one or more UDP ports and one or more TCP ports.
8. The one-way data transfer system of claim 5 , wherein the two or more different types of transport layer protocols comprise UDP and TCP.
9. A non-transitory machine readable medium having instructions stored on a send node and on a receive node, the send node and the receive node interconnected by a single one-way link for unidirectional transfer from the send node to the receive node, the single one-way link having an input and an output, the single one-way link adapted to transfer data only from the input to the output and to prevent any signal from passing from the output to the input, the instructions, when executed by the send node, causing the send node to:
maintain two or more open sockets to receive the data in two or more different types of transport layer protocols from source platforms;
receive the data in the two or more different types of transport layer protocols;
replace an Internet Protocol (IP) information of the source platforms with a channel number; and
transmit the data in the two or more different types of transport layer protocols concurrently across the one-way link,
and the instructions, when executed by the receive node, causing the receive node to:
forward the data in the two or more different types of transport layer protocols received from the send node to destination platforms,
wherein an IP information of the destination platforms remains undisclosed at the source platforms.
10. The non-transitory machine readable medium of claim 9 , wherein the two or more different types of transport layer protocols comprise UDP and TCP.
11. The non-transitory machine readable medium of claim 9 , wherein the two or more open sockets comprise one or more UDP ports and one or more TCP ports.
