Demonstration of Autonomic End-to-End QoS Assurance over SDN-based QKD-Secured Optical Networks

We demonstrate autonomic end-to-end quality-of-service assurance over quantum-key-distribution-secured optical networks, which enhances software-defined-networking control-loops with knowledge engine and cross-layer collaboration. Its performances are verified on our testbed and achieve millisecond-level latency without human intervention.
