Abstract
SAFEbus is slated to become the first standard backplane bus for
commercial avionics. It has been accepted as the draft for ARINC Project
Paper 659. SAFEbus is designed to provide communications of all data
among the line replaceable modules in the Boeing 777 Airplane
Information Management System (AIMS) cabinets. The success of an
integrated cabinet hinges on the backplane bus. It is the mechanism
responsible for maintaining the space and time partitioning required to
ensure that independent functions, which are sharing the cabinet
resources, cannot adversely affect each other, even if the designs of
one or more of the functions are faulty. A custom protocol is necessary
since no existing standard bus was found to provide the fault tolerance
or partitioning required for AIMS validation
