摘要:

汽车技术的进步要求网络能够支持多种通信要求,如可靠性、实时性、低抖动和严格的延迟限制。时间敏感网络(time sensitive network, TSN)是建立在车载以太网的IEEE 802架构上的一个保障关键帧传输延迟解决方案。为了分析TSN协议在车载以太网应用中各个机制的性能,包括单独使用和组合使用时的情况,本文基于OMNeT++设计了车载以太网TSN网络仿真系统,同时,利用仿真系统对IEEE 802.1Qbv定义的分时调度机制进行了车载应用的性能评估,最后通过搭建车载TSN网络嵌入式平台,进一步验证分时调度的性能和修正网络仿真模型。结果表明,分时调度机制除了保证时间敏感流的实时性,仍然可以为其他的流量类提供出色的传输。

Abstract:

The advancement of automotive technology requires networks to support a variety of communication requirements, such as reliability, real-time performance, low jitter, and strict delay limits. Time Sensitive Network (TSN) is a keyframe transmission delay guarantee solution based on IEEE 802 architecture of automotive Ethernet. In this paper, the TSN automotive Ethernet network simulation system is designed based on OMNeT++ to analyze the performance of various mechanisms of the TSN protocol in vehicle Ethernet application, including when used alone or in combination. At the same time, the performance of the vehicle application is evaluated by using the simulation system for the time-aware scheduling mechanism defined by IEEE 802.1Qbv. Finally, the automotive TSN network embedded platform is built to further verify the performance of time-aware scheduling and modify the network simulation model. The results show that the time-aware scheduling mechanism can not only guarantee the real-time performance of time-sensitive traffic, but also provide excellent transmission for other traffic classes.
