针对大规模时间敏感网络中时间触发流量的确定性时延问题,提出了一种分组调度机制。所提机制通过拓扑修剪策略和基于谱聚类的流分组策略,避免了由于网络拓扑规模和流量规模剧增对调度响应速度的影响,提升了调度计算效率。仿真实验结果表明,所提机制在大规模调度的场景下,可以在较短时间内进行模型的求解,并且保证一定的调度成功率。
In order to achieve the deterministic delay of time-triggered traffic in a large-scale time-sensitive network
a kind of group-scheduling mechanism was proposed.By designing a topology pruning strategy and a flow grouping strategy based on spectral clustering
the impact of the rapid increase in network topology scale and traffic scale on the speed of scheduling response was avoided
and the scheduling calculation efficiency was improved.The results of experiment show that the mechanism can solve the model in a relatively short time for large-scale scheduling problem and achieve a relatively high scheduling success rate.
