In our work, we model the service process of quantum repeater nodes which support link-level entanglement establishment, multi-round purification and entanglement swapping, and derive their service availability based on the concept of queuing theory. Then, we propose a link-disjoint multi-path routing algorithm in the prevention of potential failure or memory shortage, with repeatersĄŻ availability, linksĄŻ fidelity and classical delay taken into consideration. Besides, we develop a simulation platform to analyze the performance of quantum communication networks based on a discrete event simulation engine.
