Schedulability Analysis of Ethernet AVB Switches
20th IEEE International Conference on Embedded and Real-Time Computing Systems and Applications (RTCSA 2014), Chongqing, China, Aug. 20-22, 2014.
Ethernet AVB is being actively considered by the automotive industry as a candidate for in-vehicle communication backbone. However, several questions pertaining to schedulability of hard real-time messages transmitted via such a switch remain unanswered. In this paper, we attempt to fill this void. We derive equations to perform worst-case response time analysis on Ethernet AVB switches by considering its credit-based shaping algorithm. Also, we propose several approaches to reduce the pessimism in the analysis to provide tighter bounds.
