Demonstration of Hierarchical SDN Orchestration for End-to-End Key Provisioning in Large-Scale Quantum Key Distribution Networks
Yazi Wang, Xiaosong Yu, Zihao Wang, Yuan Cao, Yongli Zhao, Jie Zhang · 2023
We experimentally demonstrate end-to-end key provisioning among multiple QKDNs with a hierarchical SDN orchestration architecture, where the computational complexity is reduced via abstracted hierarchical network views and the seconds-level latency without manual intervention is achieved.
