The Quantum Key Distribution(QKD)network consists of network nodes connected according to a certain topological structure.The existing QKD networks can be divided into three main categories of optical node
trusted relay node and quantum node QKD network in view of their node performances.This paper reviews the research progress of the QKD networks and makes an all-round comparisons and analysis of their structures and performances
on the basis of which a novel highly-efficient and practical QKD network scheme is presented.
