摘　　要：随着无线电和卫星小型化技术的进一步成熟,大规模低轨卫星网络得到了长足发展,面对网络传输业务的时延、带宽、丢包率等服务质量的差异化需求,如何在低轨卫星网络中实现服务质量保障路由,成为了研究关注的关键问题。通过介绍低轨卫星网络服务质量保障路由的场景与需求,总结并分析了当前的研究成果。首先,针对传统网络中的服务质量保障路由算法,总结了三类经典的路由计算方法。然后,对于软件定义网络和确定性网络中的服务质量保障路由算法,结合各自的网络特点,分析总结了各自场景下的路由算法。With the further maturation of radio and satellite miniaturization technologies,large-scale Low Earth Orbit(LEO)satellite networks have seen significant development.Facing differentiated Quality of Service(QoS)requirements in network transmission,such as latency,bandwidth,and packet loss rate,implementing QoS-assured routing in LEO satellite networks has become a key issue of research focus.This paper introduces the scenarios and requirements for QoS-assured routing in LEO satellite networks and summarizes and analyzes current research findings.Initially,it reviews three classic routing calculation algorithms in traditional networks targeted at QoS assurance.Subsequently,for QoS-assured routing algorithms in software-defined networks and deterministic networks,it analyzes and summarizes the respective routing algorithms in conjunction with their unique network characteristics.
