Abstract

An apparatus is provided. The apparatus comprises a processing system comprising: an ARINC 429 converter system; an Internet protocol (IP) suite; and an Ethernet driver; wherein the processing system is configured to be coupled to a communications management system and at least one IP radio; wherein the processing system converts data, from the communications management system, from an ARINC 429 protocol into a transport layer protocol, an IP and a Ethernet protocol; and wherein the processing system converts data, from the IP radio, from the Ethernet protocol, IP, and transport layer protocol to the ARINC 429 protocol.

Claims

1. An apparatus, comprising:

a processing system comprising processing circuitry coupled to memory circuitry;

wherein the processing system is configured to be communicatively coupled to a communications management system and at least one Internet protocol (IP) radio;

wherein the processing system is configured to convert data, from the communications management system, from an Aeronautical Radio Incorporated (ARINC) 429 protocol into at least one of a transport layer protocol, an IP, and an Ethernet protocol by;

extracting payload data from each link data unit (LDU) of the data in the ARINC 429 protocol;

forming a total data payload by combining the payload data from each LDU;

creating at least one of;

at least one transport layer segment each of which comprises at least a portion of the total data payload, where each transport layer segment has a transport layer segment header;

at least one IP packet by generating an IP packet header for each of the at least one transport layer segment, and adding the IP packet header to the corresponding transport layer segment; and

at least one Ethernet frame by generating an Ethernet header and an Ethernet trailer for each of the at least one IP packet, and adding the Ethernet header and the Ethernet trailer to respectively the beginning and end of the corresponding IP packet; and

wherein the processing system is configured to convert data, from the at least one IP radio, from the Ethernet protocol to the ARINC 429 protocol by;

extracting at least one of data payloads of each transport layer segment and datagrams of each IP packet;

creating a total data payload by combining one of the extracted data payloads and the extracted datagrams;

segmenting the total data payload into segmented payload data; and

generating a link data unit (LDU) for each segmented payload data.

2. The apparatus of claim 1, wherein the processing system further is further configured analyze security data appended to a total data payload received by the at least one IP radio.

3. The apparatus of claim 2, wherein the security data comprises at least one of a digital signature and a cyclic redundancy check value.

4. The apparatus of claim 2, wherein the processing system is further configured to append security data to a total data payload data received from the communications management system.

5. The apparatus of claim 1, wherein the processing system further comprises an address lookup database comprising at least one destination IP address.

6. The apparatus of claim 1, wherein the processing system is part of a display controller.

7. The apparatus of claim 1, further comprising the communications management system coupled to the processing system;

wherein the communications management system is configured to be coupled to at least one non-IP radio;

wherein the communications management system comprises a first processing system comprising a router; and

wherein the router routes data to and from the at least one IP radio.

8. The apparatus of claim 7, wherein the communications management unit comprises a portion of an IP suite.

9. A method, comprising:

receiving data in an Aeronautical Radio Incorporated (ARINC) 429 protocol from a communications management system;

converting data in the ARINC 429 protocol to an Ethernet protocol by;

extracting payload data from each link data unit (LDU) of the data in the ARINC 429 protocol;

forming a total data payload by combining the payload data from each LDU;

creating at least one of;

at least one transport layer segment each of which comprises at least a portion of the total data payload, where each transport layer segment has a transport layer segment header;

at least one IP packet by generating an IP packet header for each of the at least one transport layer segment, and adding the IP packet header to the corresponding transport layer segment; and

at least one Ethernet frame by generating an Ethernet header and an Ethernet trailer for each of the at least one IP packet, and adding the Ethernet header and the Ethernet trailer to respectively the beginning and end of the corresponding IP packet;

transmitting the converted data to an IP radio;

receiving data in an Ethernet protocol, Internet protocol (IP), and transport layer protocol from an IP radio;

converting the data in the Ethernet protocol to the Aeronautical Radio Incorporated (ARINC

     429) protocol by;

extracting at least one of data payloads of each transport layer segment and datagrams of each IP packet;

creating a total data payload by combining one of the extracted data payloads and the extracted datagrams;

segmenting the total data payload into segmented payload data; and

generating a link data unit (LDU) for each segmented payload data; and

transmitting the converted data to a communications management system.

10. The method of claim 9, further comprising appending security data to the total data payload.

11. The method of claim 9, wherein converting data in the ARINC 429 protocol to the Ethernet protocol comprises converting data in the ARINC 429 protocol to a transport layer protocol and an Internet protocol (IP).

12. The method of claim 9, wherein each LDU is comprised of words.

13. The method of claim 9, further comprising:

extracting security data; and

verifying the security data.

14. The method of claim 13, further comprising discarding the total data payload if the security data cannot be verified.

15. The method of claim 13, wherein extracting security data comprises extracting at least one of a cyclic redundancy check (CRC) value and a digital signature from a total data payload.

16. The method of claim 9, wherein converting data in the Ethernet protocol to the ARINC 429 protocol comprises converting data in the Ethernet protocol to an Internet protocol (IP) and a transport layer protocol.
