Design of single stream reservation class for efficient data transmission in IEEE 802.1 AVB networks
New automotive applications such as infotainment and driver's assistance have more bandwidth requirement and more stringent latency/jitter constraints. IEEE 802.1 Audio/Video Bridging (AVB) protocol suite is expected to guarantee the requirements in Ethernet-based car communication. IEEE 802.1 AVB defined Stream Reservation Classes (SR-Class) for forwarding and queuing of AVB traffic. The standards recommended using two SR-Classes. However, vehicle industry decided to use only one SR-Class in in-car network. In this paper, we use the network simulation tool OMNeT++ to simulate a real in-car network design and traffic model. Through simulations we confirm that using one SR-Class meets the AVB traffic requirements and it has several advantages.
