Abstract

Abstract: Performance evaluation can provide strong support for new technology verification of low earth orbit(LEO) satellite internet. Aiming at the characteristics of flexible networking and large spacetime scale of satellite internet, a performance evaluation architecture of satellite internet is designed. Aiming at the characteristics of various performance elements, a performance evaluation index system is designed under the premise of multi-dimensional comprehensive consideration. Aiming at the problem of frequent switching of satellite-ground links caused by high-speed movement, an algorithm for satelliteground link switching is proposed, which provides support for subsequent collection work. Aiming at the multi-dimensional problem of indicators, a multi-mode collection technology for indicator source data is proposed, which improves the efficiency of data. Aiming at the requirement of how to evaluate performance through a standardized process, a satellite Internet performance evaluation strategy is designed. Experiments show that compared with traditional methods, data acquisition performance improved by 47.16%. It has the ability to realize the systematic and comprehensive performance evaluation of LEO satellite internet.
