| Abstract: | This paper develops a QKD (quantum key distribution)-based queueing
model to investigate the data delay on QKD link and network,
especially that based on trusted relays. It shows the mean
packet delay performance of the QKD system. Furthermore, it proposes a
key buffering policy which could effectively improve the delay
performance in practice. The results will be helpful for quality of
service in practical QKD systems. |
