The scope of ARINC 664, Part 5 is to provide general design and implementation guidelines that, when they are implemented by aircraft devices and configured by the system integrator, the devices provide the required connectivity, quality of service, safety and security. The form, fit and function specification of ARINC characterized devices is out-of-scope for this document and will be provided by other ARINC specifications.

Purpose of Document

The purpose of ARINC Specification 664: Aircraft Data Network, Part 5 – Network Domain Characteristics and Interconnection, is to provide design and implementation guidelines for networks installed in aircraft. Such networks may be used to allow network devices to communicate among themselves and with networks outside of the aircraft.

ARINC 664, Part 5 defines a set of domains within the aircraft. The domains are defined in terms of the services they provide, the security they provide to the functions within their boundaries, and the connections required between a domain and other domains and networks external to the aircraft.
