论文摘要
在现代SD-WAN网络中，全局控制器通过为每个应用程序选择适当的路由策略不断优化应用程序和用户意图。但是，在每个覆盖链接上仍然可以进行流之间的竞争，并且可能会降低服务质量（QoS）。为了减轻交通拥堵的绩效降解，还可以动态优化QoS策略以限制低优先级流量的速率并以公平的方式在所有流中共享带宽。该演示提供了一个全面的控制平面体系结构，以协调路径选择和速率分配，以便满足应用程序要求，同时优化全球目标（例如，拥塞低，最佳质量和最低成本）。
In modern SD-WAN networks, a global controller continuously optimizes application and user intents by selecting the proper routing policies for each application. Nevertheless, the competition between flows can still occur at each overlay link and it may degrade Quality of Service (QoS). To mitigate performance degradations in case of congestion, QoS policies can also be dynamically optimized to limit the rate of low-priority flows and share the bandwidth among all flows in a fair manner. This demonstration presents a comprehensive control plane architecture to coordinate path selection and rate allocation, in order to meet application requirements while optimizing a global objective (e.g., low congestion, best quality, and minimum cost).
