SDN-Enabled Reconfigurable Optical Data Center Network with Automatic Network Slicing to Provision Dynamic QoS

An SDN-controlled optical DCN enabling automatic QoS-driven network-slice provisioning, reconfiguration and flow-priority updating is demonstrated for the first-time. Network-slice reconfigurations with guaranteed QoS based on monitored statistics are achieved within 125 ms with 3.485 μs server-to-server latency and zero packet-loss at 0.7 load for high-priority.
