用基于路径的流汇集调度提高延迟性能

Improving Delay Performance with Path-Based Flow Aggregation

文章介绍了基于路径的汇集调度的基本方法,提出了一个新的汇集器算法,分析了路径汇集的延迟性能和影响性能的因素,并用大量的实验考察了基于路径的流汇集调度在性能方面的特点。实验结果表明,基于路径的流汇集调度在提高扩展性的同时,可以为实时应用提供满意的延迟保证,其性能在一定条件下甚至优于每流状态的调度。

A path-based flow aggregation scheduling method in domain model is proposed in this paper to support the scalability as well as delay guarantee in high-speed network. We firstly introduce the basic model of flow aggregation,then proposed a new fair aggregator and derive the condition to improve the delay performance compared with per-flow queue method. Our work shows that path-based flow aggregation can get good QoS performance as well as good scalability.
