摘要:

为解决时间敏感网络中时间敏感流量调度与路由分离导致的端到端传输时延不确定的问题,提出了一种联合路由规划的多约束流量调度方法。所提方法结合时间敏感流量的流间冲突度,灵活分配流量路由,在此基础上建立时间感知整形和联合无冲突路由的调度约束模型,在时间和空间2个维度严格保障时间敏感流量调度的有界低时延需求。实验结果表明,所提方法在不同类型拓扑场景下均表现出良好的时延性能,在保证链路均衡负载的同时,有效降低了不同时间敏感流量规模下由于拥塞冲突而产生的时延。

Abstract:

To solve the problem of uncertain end-to-end transmission delay caused by the separation of time-sensitive traffic scheduling and routing in time-sensitive network, a multi-constrained traffic scheduling method with joint routing planning was proposed.The inter-flow conflict degree of time-sensitive traffic was introduced to flexibly allocated traffic routing.On that basis, a scheduling constraint model of time-aware shaping and joint conflict-free routing was established to strictly guarantee the time-sensitive traffic scheduling with bounded low latency in both spatial and temporal dimensions.Experimental results show that the proposed method has good delay performance in different topological scenarios, and effectively reduces the delay caused by congestion conflicts under different time-sensitive traffic scales while ensuring link load balancing.

Key words: time-sensitive network, time-sensitive traffic, traffic scheduling, conflict-free routing, low delay
