The IEEE 802.1 Audio/Video Bridging (AVB) protocol successfully supports audio/video streaming over Ethernet networks and is also a promising candidate for industrial automation. However, several industrial automation applications feature requirements that cannot be fulfilled by the current AVB standard. The next generation of IEEE 802.1 standards, which will specifically target the requirements of automotive and industrial control, is under specification within IEEE 802.1 Working Group. Inspired by such an ongoing work, this paper addresses the introduction in IEEE AVB networks of scheduled traffic, i.e., high priority traffic that is transmitted according to a time schedule so as to ensure no interference from other traffic classes. The paper describes the proposed approach, discusses the design choices and presents a performance assessment based on OMNeT++ simulations.
