QoS Evaluation of combination SPQ, FRER and FP for In-Vehicle Networks

Abstract

This paper evaluates QoS of the next-generation in-vehicle Ethernet-based networks in combination with the following three controls defined in IEEE 802.1TSN by simulation. The authors target Strict Priority Queueing (SPQ), Frame Replication and Elimination for Reliability (FRER) and Frame Preemption (FP). The experimental results indicate the followings. First, traffic of the highest priority should be applied SPQ to guarantee its QoS. Second, it is necessary to adopt an appropriate combination of QoS control for traffics of other priority in order to prevent them from deteriorating too much.
