一种应用于大规模时间敏感网络的混合流量调度机制
A hybrid traffic scheduling mechanism applied to large scale time-sensitive networking
摘要
Abstract
Aiming at large-scale time-sensitive networking(TSN)scenarios that can only ensure frequency synchroniza-tion between devices,a hybrid traffic scheduling mechanism was proposed based on time-aware shaper(TAS)combined with cycle specified queuing and forwarding(CSQF).Firstly,a scheme was investigated for achieving periodic cyclic mapping alignment between two adjacent nodes located in different time domains.Secondly,combining segment routing technology,a heuristic algorithm based on CSQF mechanism for joint routing and scheduling was proposed to complete resource allocation for large bandwidth traffic.The experimental results show that the proposed scheme significantly im-proves the system resource utilization and scheduling success rate compared to existing research results,achieving effi-cient TSN traffic scheduling in wide area network scenarios.关键词
