当今的互联网架构仅提供“尽力而为”的服务，因此无法保证应用程序的服务质量（QoS）。软件定义网络（SDN）是一种新的计算机网络方式，它将控制平面和转发平面分离，具有集中控制和可编程性的优点。在本文中，我们提出了使用 SDN 提供 QoS 保证的 HiQoS。此外，HiQoS利用源和目的地之间的多条路径以及排队机制来保证不同类型流量的QoS。实验结果表明，我们的HiQoS方案可以减少延迟并提高吞吐量以保证QoS。非常重要的是，HiQoS 通过将流量从故障路径重新路由到其他可用路径，可以非常快速地从链路故障中恢复。
Today's Internet architecture provides only “best effort” services, thus it cannot guarantee quality of service (QoS) for applications. Software Defined Network (SDN) is a new approach to computer networking that separates control plane and forwarding planes, and has the advantage of centralized control and programmability. In this paper, we propose HiQoS that provides QoS guarantees using SDN. Moreover, HiQoS makes use of multiple paths between source and destination and queuing mechanisms to guarantee QoS for different types of traffic. Experimental results show that our HiQoS scheme can reduce delay and increase throughput to guarantee QoS. Very importantly, HiQoS recovers from link failure very quickly by rerouting traffic from failed path to other available path.
