SDN Control of QKD and Classical With Time Sharing Algorithm


ML-assisted and SW QKD Network Supporting Co-existance

• Apply real-time monitors network-wide (spectrum, power, noise, channels spacing, secret key rate - SKR, QBER, probability of detection..)

• Feed and train the Machine Learning algorithm to optimize Q-Ch

• Develop SDN architecture to re-configure the network based on the ML output

• Dynamically deploy Optical network connectivity for VNF chaining in multiple Data Centers

• Dynamically Mix & Match VNFs from multiple islands

• Use inter-DC optical network for high bandwidth and low latency VNF requirements

• Create secured inter-DC connectivity for VNF chaining using QKD within same fiber as classical traffic

• Highly dynamic secure optical connectivity from multiple access devices to edge and metro DC for 5G Virtual Service
