ABSTRACT: 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.
