论文摘要
Virtualisation First和云计算后来导致数据中心的工作负载合并,这还包括对延迟敏感的应用程序域,例如高性能计算和电信。这些类型的应用需要严格的延迟保证才能维持其服务质量。在虚拟化的环境中,这需要适应性和灵活性满足。同时,基础架构的规模比专业(Infiniband)硬件更喜欢商品(以太网)。为此,本文介绍了一种新型的交通管理算法,该算法分别结合了限制性的严格优先级和赤字循环蛋白,分别为延迟感知和公平计划。此外,我们通过根据基于标准的优先级和最佳效果计划对BMV2 P4软件开关进行了该算法的实现。
Virtualisation first and cloud computing later has led to a consolidation of workload in data centres that also comprises latency-sensitive application domains such as High Performance Computing and telecommunication. These types of applications require strict latency guarantees to maintain their Quality of Service. In virtualised environments with their churn, this demands for adaptability and flexibility to satisfy. At the same time, the mere scale of the infrastructures favours commodity (Ethernet) over specialised (Infiniband) hardware. For that purpose, this paper introduces a novel traffic management algorithm that combines Rate-limited Strict Priority and Deficit round-robin for latency-aware and fair scheduling respectively. In addition, we present an implementation of this algorithm on the bmv2 P4 software switch by evaluating it against standard priority-based and best-effort scheduling.
