The purpose of this Handbook is to provide the network designer and developer with some guidelines to develop an Ethernet databus framework deployable in aircraft avionics systems. The Handbook gives design rationale and requirements for the use of Ethernet-based networks in the avionics environment and identifies the relevant issues and concerns regarding the determinism of the databus system. The Handbook will aid in the process of qualifying an Ethernet-based databus as part of the overall aircraft certification. It focuses on identifying any and all aspects of the product that may impact its qualification. Some qualification issues related with Ethernet-based aviation databuses are discussed. The general acceptance criteria for the qualification of avionics databuses as well as the evaluation criteria specific to Ethernet-based databuses are discussed. The Handbook describes the safety, performance, and reliability requirements of an Ethernet-based databus. Using the requirements of Ethernet-based databuses as a basis, the guidelines to design Ethernet-based aviation databuses and to address nondeterministic factors are illustrated. This Handbook does not constitute Federal Aviation Administration certification policy or guidance but may be used as input to future policy and guidance.
