Abstract

Comprehensive overview about the basic principles behind IEEE AVB Especially the credit based shaper algorithm (CBS) and the clock synchronization algorithm could be implemented accordingly to Aeronautic requirements Multiple onboard applications dealing with video and audio in a non-safety critical environment could benefit with immediate effect of AVB The set of AVB standards offer a complete framework and toolbox for sending real-time audio and video streams based on standard Ethernet Combination of different traffic classes not sufficient solved (best effort, starvation due to SPQ) Future work of our group will address the second generation of the AVB standard with focus on timing / latency analysis and failure modes.
