P4-based implementation of traffic engineering with service priority

With the growth of network services in recent years, the integrated design of service-guaranteed virtual private networks and traditional best-effort networks has been required. For such integrated design, traffic engineering is an important technology in order to accommodate the rapidly increasing traffic. In the past, a traffic engineering method considering service priority has been proposed, which determines routing paths of traffic for each network service, assuming that various types of services are deployed on an integrated network. In this paper, we examine the implementation of the traffic engineering method, using P4 language which can describe data plane operations in software-defined networking. We confirm the operation through demonstration experiments.
