基于随流检测的确定性网络混合时敏流量调度技术研究
Research on hybrid scheduling of time-sensitive flow in deterministic networking based on in-situ flow information telemetry
摘要
Abstract
The development of Industry 4.0 and smart factories places higher demands on deterministic low latency and low jitter for network transmission.To address the issue of hybrid transmission of event-triggered flows and time-triggered flows in large-scale deterministic network,an in-situ flow earliest deadline first scheduling(IFEDS)based on in-formation telemetry for hybrid time-sensitive flows was proposed.The networking telemetry and packet coloring were achived based on the in-situ flow information telemetry.A deadline-based probabilistic packet coloring algorithm and a coloring-based semi-preemptive earliest deadline first scheduling algorithm were designed.Simulation results based on the OMNeT++show that the average end-to-end latency of IFEDS under high load is 6.84%lower than Deadline-TSN,and the packet loss rate is reduced by 0.37%compared with Deadline-TSN when the event-triggered flow ratio is 40%.关键词
