论文摘要
启用边缘的工业互联网(IIOT)平台对于加速智能行业的发展具有重要意义。但是,随着实时IIT应用程序的急剧增加,支持快速响应时间,低潜伏期和有效的带宽利用率是一个巨大的挑战。为了解决这个问题,最近研究了时间敏感网络(TSN),以通过确定性调度来实现低延迟通信。据我们所知,以前从未对多个流量的组合性(可以显着影响计划表现)进行系统分析。在本文中,我们首先分析可组合性问题。然后提出了基于非碰撞理论的确定性调度(NDS)方法来实现时间敏感流的超低潜伏期通信。此外,为了提高带宽利用率,为最佳富度流提供了动态队列调度(DQS)方法。实验结果表明,NDS/DQ可以很好地支持确定性的超低潜伏期服务并确保有效的带宽利用率。
Edge enabled Industrial Internet of Things (IIoT) platform is of great significance to accelerate the development of smart industry. However, with the dramatic increase in real-time IIoT applications, it is a great challenge to support fast response time, low latency, and efficient bandwidth utilization. To address this issue, Time Sensitive Network (TSN) is recently researched to realize low latency communication via deterministic scheduling. To the best of our knowledge, the combinability of multiple flows, which can significantly affect the scheduling performance, has never been systematically analyzed before. In this article, we first analyze the combinability problem. Then a non-collision theory based deterministic scheduling (NDS) method is proposed to achieve ultra-low latency communication for the time-sensitive flows. Moreover, to improve bandwidth utilization, a dynamic queue scheduling (DQS) method is presented for the best-effort flows. Experiment results demonstrate that NDS/DQS can well support deterministic ultra-low latency services and guarantee efficient bandwidth utilization.
