摘　　要：分析了三层卫星光网络的链路类型、时延和网络稳定性等参数,结果表明与单层卫星光网络比较,三层卫星光网络吞吐量大、鲁棒性强。同时由于其结构复杂导致网络中链路负载加重、路由表计算量和阻塞概率增大。这为今后卫星光通信组网技术研究和空间光通信协议的拟定提供了参考。Link types, delay and network stability in the novel three-layer optical satellite network are analyzed. Compared with single layer optical satellite network, the novel three-layer optical satellite network has larger throughput and stronger enhanced robustness. At the same time, load of links and calculation of route table are increased as a result of network complexity. Analysis above would be of reference value for the research of optical satellite communication networking technology and protocol design in optical space communication in future
