SDN-controlled and Orchestrated OPSquare DC Architecture enabling Network Slice Deployment with QoS guarantees

We present a DC architecture that enables QoS-driven network slices reconfiguration. Per-slice monitoring information is collected; upon potential QoS degradation, reconfiguration of the slice network connectivity is triggered. The experimental assessment shows reconfiguration times below 150ms, even in large DCs.
