Software-Defined Networking (SDN) is a networking paradigm that decouples the control plane of a network from its forwarding plane and offers programmability of the data plane devices to manage and control the ongoing traffic flows. This paper presents the control plane architecture of a Datacentre network (DCN) and its operational services being developed for NEPHELEs optical network infrastructure. The heart of the proposed control plane overlay is an OpenDaylight SDN controller, which along-with its north and south-bound interfaces bridges the gap between the cloud applications and the DC network configuration at the data plane, in order to automatically adjust the underlying network to the Quality of Service (QoS) requirements at the application level. An application based traffic shaping use case is presented as a proof of concept of applicationaware networking in SDN-enabled data center networks.
