This document serves as an ARINC standard to define a Common IPS Radio Interface (CIRI) protocol for conveying radio status information and for transferring digital data between the Airborne IPS System and Airborne Radios. This standard includes the functional description of the protocol including applicable use cases, protocol message formats, and protocol operation for both control plane and data plane exchanges. The protocol is intended to operate over a variety of on-aircraft communication means including, but not limited to, ethernet-based and ARINC 664-based aircraft networks.
Purpose
As described in ARINC 858 Part 1, the Airborne Internet Protocol Suite (IPS) System must provide a datalink adaptation function to accommodate existing radio-specific interfaces. Although these radio-specific interface specifications are well-established within the respective radio standards, it is envisioned that ARINC Standards may need to evolve to accommodate IPS services. As these updates occur, there is an opportunity to harmonize the radio interface protocol and minimize the need for radio-specific adaptations in the Airborne IPS System.
The Common IPS Radio Interface (CIRI) protocol specified in this standard is intended to facilitate this harmonization by providing a standardized means to exchange status and information in a manner that allows different Airborne Radios to assess/present link status and to manage the flow of information consistent with the radio’s abilities. Therefore, the CIRI protocol should be adopted, by reference to this standard, as the radio standards are updated.
