Survey on scheduling mechanisms of time-sensitive networking traffic

时间敏感网络作为一种确定性网络技术,能够通过多种流量调度机制确保关键流量进行具有确定延迟边界的实时传输,具有重要的应用价值。从实现原理角度,分析对比时间敏感网络各调度机制的特点;分析各调度机制的基本原理和研究重点,并以调度性能提升为主线,梳理各调度机制研究进展;针对当前的研究盲区,阐述时间敏感网络流量调度机制的研究趋势。

As a deterministic network technology,Time-Sensitive Networking(TSN)can ensure the real-time transmission of critical traffic with a definite delay boundary through a variety of traffic scheduling mechanisms,which is of a great application value.Firstly,from the perspective of implementation principle,the characteristics of various TSN scheduling mechanisms are analyzed and compared.Then,the basic principle and research emphasis of each scheduling mechanism are introduced,and,with the improvement of scheduling performance as the focus,the research progress of each scheduling mechanism is reviewed.At last,aiming at the current research gap,research trends of TSN scheduling mechanisms are proposed.
