Abstract

SDN is wildly studied as it enables new services and enhances existing services for telecom operators. Operators with large-scale optical transport networks might tend to operate newly-built SDN networks and legacy transport networks in parallel and gradually retire legacy devices. This study proposes a mediator approach to fulfill bandwidth adjustment demand with both SDN-ready and legacy devices. We applied the proposed approach to large-scale networks. The experiment result shows that this approach is feasible and brings higher hit ratio.
