随着Internet通信量的持续增长，需要一种机制来确保适合不同应用程序的通信质量。OpenFlow实现了逐流路由控制，但当流项数量增加时，可能会对通信质量产生不利影响。在这项研究中，我们提出了一种路由方法，通过标记代表源交换机、目的交换机和所需通信质量的数字来控制流量。然后，OpenFlow控制器以每个标签为基础而不是以每个流为基础设置流项，从而允许它减少流项的数量。在评估测试中，我们证实了标记方法可以防止这种通信质量的降低。
As the volume of Internet traffic continues to grow, there is a need for mechanisms that ensure communication quality that is suitable for different applications. OpenFlow implements per-flow routing control but can have adverse effects on communication quality when the number of flow entries is increased. In this study, we propose a routing method that controls traffic flows by labeling them with numbers representing the source switch, destination switch and required communication quality. The OpenFlow controller then sets up flow entries on a per-label basis rather than on a per-flow basis, allowing it to reduce the number of flow entries. In an evaluation test, we confirmed that the labeling method could prevent this reduction in communication quality.
