Abstract
As a key part of Next Generation Network (NGN) infrastructure, next generation satellite networks are expected to support a variety of applications with diverse performance requirements. This paper argues the necessities of developing built‐in Low Earth Orbit (LEO) satellite constellation inference algorithms. Combined with thorough understanding of the characteristics of underlying satellite network and traffic dynamics, constellation inference is the preliminary step to provide Internet Service Providers (ISPs) an efficient way for network monitoring, system design, traffic engineering and performance promotion.
To infer the constellation, a divide‐and‐conquer mechanism is developed for each parameter estimation by delay probing carried out between two terminals located at the same geographic positions. Performance evaluation on several popular polar LEO constellations proves the accuracy and efficiency of the developed constellation measurement algorithms. The geographic position limitation of the delay probing terminals for a valid constellation inference is also analysed in the paper. Copyright © 2007 John Wiley & Sons, Ltd.
