Chenhui Ma, Yixi Guo, SU Jin-hai, Chao Yang · 2016
A better routing scheme becomes more significant with the quantum key distribution network developing. This paper makes use of pre-relay, parallel work and shortest path first strategy and proposes a hierarchical routing scheme with the perspective of parallel processing on wide-area quantum key distribution network based on trusted relay. Then the paper proposes the hierarchical routing algorithm. Through theoretical analysis and experiment result, it shows that the hierarchical routing scheme can effectively shorten the key transmission time and improve the efficiency of key transmission, which is better than the single layer routing scheme.
