Abstract
The introduction of quality of service (QoS) features for socket-based communication over InfiniBand networks provides the opportunity to enact service differentiation for traditional socket-based applications over high performance networks for the first time. The effectiveness of such techniques in providing control over the quality of service that individual connections experience is important in managing traffic in modern data centers. In this paper, we quantitatively analyze the performance benefits of QoS provisioning in InfiniBand networks for sockets direct protocol (SDP) and IPoIB. We find that QoS provisioning can provide prioritized service for sockets-based streams, with more apparent impact on SDP traffic than IPoIB.
InfiniBand网络上基于套接字通信的服务质量(QoS)特性的引入，首次为高性能网络上传统的基于套接字的应用程序提供了实现服务差异化的机会。这些技术在控制单个连接体验的服务质量方面的有效性对于管理现代数据中心的流量非常重要。在本文中，我们定量分析了在InfiniBand网络中针对socket direct protocol (SDP)和IPoIB提供QoS的性能优势。我们发现QoS配置可以为基于套接字的流提供优先级服务，对SDP流量的影响比IPoIB更明显。
