Research on the Control Method of the Ground Transmission Flow of Satellite Data Based on the Token Bucket Algorithm

该文根据卫星数据的特点,在研究令牌桶算法的基础上,提出了一种改进的令牌桶算法,增加了两个模块:令牌放置模块和令牌请求模块,在模拟环境下实现该算法。在对卫星数据进行流量控制的同时,降低了数据传输过程中的抖动,并保证了卫星实时数据的低时延和非实时数据尽量大的带宽,在模拟环境下进行测试,达到了较好的效果。

According to the characteristics of satellite data,a improved token bucket algorithm based on the research of token bucket algorithm is proposed, two modules were increased:token placed module and token request module,we implement the algorithm in a simulated environment.we reduce the jitter in the data transmission process,and ensure the low delay of real-time satellite data and the much more bandwidth of non real-time data,we test the procedure in a simulated environment and achieved good results.
