摘　　要：结合卫星网络拓扑结构的时变性特点,建立了时变卫星光网络模型,对网络模型进行离散化,形成一系列相对固定的网络拓扑结构。通过优化传统的Dijkstra算法,提出了NNSP算法,把它引入到卫星光网络副载波/光波的双层路由算法中,最后仿真比较了网络延时,进一步证明卫星光网络路由算法的可行性。Combines time-varying feature of the satellite network topology structure, establish the new pattern of the time-varying satellite optical network model, carries on the discretization to the network model, forms a series of relative steady network topology structure. Utilizes traditional satellite network of Dijkstra algorithm to optimize, the NNSP algorithm is proposed. So leads it to the two layers routing algorithm of sub-carrier/wavelength, and TCP delay are put to comparable imitate,proves feasible quality of the satellite optical network Routing Algorithm by further.
