High throughput and small footprint combined with easy portability was the design aim of the host driver.The result is a three layer architecture where only the very small Glue Layer has to be adapted when porting to another OS. The host driver API offers all functionality to easily configure the AFDX Node. The BITE API is also incorporated in the driver API (see details at right). PikeOS drivers as well as LynxOS-178 and Linux drivers are available.

Because ICMP and SNMP both reside on the AFDX Node, the host OS dependency is minimized. Having both services on the AFDX Node also leaves more computing time for the host.

Integrity Management and Redundancy Management are basic components of the AFDX Node. The Portable AFDX from SYSGO includes a comprehensive implementation of these components, guaranteeing impressive performance.

All artifacts required to process a DO178B certification are available. The currently available documents will cover a certification up to Level B.

Any other safety critical operating system can be easily adapted by SYSGO or the customer.

The configuration service interprets the configuration information given by the host and takes all actions necessary to initialize the AFDX Node as defined. The management information base is responsible for storing information about network packet errors to ease in-flight and in-shop maintenance.

The AFDX Node is also available as an instrumented version, incorporating a debug stub and tracing capability. This enables the use of standard software development environments (IDEs) as well as checking the timing behavior without requiring the use of costly hardware analyzers.

Reference implementations are available for different airborne proven PowerPC products, including PowerQUICC II and MPC5554.

Portable AFDX from SYSGO offers 100% AFDX performance. The performance calculation is based on the AFDX performance specification.
