摘要

研究了近地轨道卫星通信中的路由和波长分配算法。基于星间跳数和波长利用率，建立了路径权值的计算模型。为了在软件定义网络(SDN)网络架构中实现路由和波长资源的最优分配，从路径权值的角度完成路径选择和波长分配。最后，将所提算法与现有算法进行了比较。仿真结果表明，该算法可以降低阻塞率，提高波长利用率。

Routing and Wavelength Assignment Algorithm for LEO Satellite Based on Path Weight

Routing and wavelength assignment algorithms for Low Earth Orbit (LEO) satellite communication are studied in this paper. Based on intersatellite hops and wavelength utilization, the calculation model of path weight is established. In order to achieve the optimal allocation of routing and wavelength resources in Software Defined Network (SDN) network architecture, path selection and wavelength allocation are completed from the perspective of path weight. Finally, the proposed algorithm is compared with the existing algorithms. The simulation results show that the proposed algorithm can reduce the blocking rate and improve the wavelength utilization.
