Abstract
In view of the problems of low level of centralized network management, low interactivity, and low flexibility in the static deployment of traditional in-vehicle network (IVN), a new type of IVN architecture was designed. At the same time, in order to effectively improve the quality of data transmission under the new IVN architecture and avoid network congestion, a quality of service (QoS) guarantee mechanism under the new architecture has been established. Firstly, the software-defined network (SDN) technology is introduced and combined with the IVN itself to design the new IVN architecture including the forwarding plane, control plane, and application plane. Secondly, the application of four packet scheduling algorithms which are Stochastic Fairness Queueing (SFQ), Priority Queuing (PQ), Class-based Weighted Fair Queuing (CBWFQ) and Low Latency Queue (LLQ) under the new architecture are introduced and analyzed. Finally, the performance of different packet scheduling algorithms are compared and analyzed, and the experimental result shows that: Compared with the other three scheduling algorithms, LLQ can provide better QoS guarantee and network performance for IVN data transmission.
