面向天地一体化信息网络的卫星链路仿真研究
Research on satellite link emulation for space-ground integration information network
摘要
Abstract
Aiming at the large scale and diverse technologies of the space-ground integration information network, it was necessary to rely on realistic satellite network scene to verify the various schemes. A method of satellite link emulation in cloud computing environment was proposed. The critical factors that affect the characteristics of satellite link were ana-lyzed, OpenStack and STK were integrated to build an emulation platform for space-ground integration information net-work. Through the link modeling and calculation, the intermittence, delay and bit error rate of satellite link based on flow table rules and queue management rules can be toggled dynamically in real time. In order to improve the throughput of satellite link, satellite nodes have dynamic routing learning ability. Satellite links can be flexibly constructed and recon-structed. The experimental results show that the method can accurately emulate the satellite link, effectively guarantee the fidelity and periodicity of satellite link emulation, and facilitate the scientific research of satellite network scene.关键词
