摘　　要：探索了AS(自治域)的地理分布以及路由器的建连距离对Internet稳定性的影响。与仅关注AS网络现状和发展趋势的传统研究角度不同,侧重研究了受到经济宏观调控或者技术突破等因素影响后AS网络的性能变化,从而为制定宏观调控措施和把握网络技术导向提供了理论依据。提出了一种AS地理超图结构,弥补了传统模型中未能正确刻画AS地理分布的缺陷,并建立了地理超图和AS网络的双层网络模型。实验结果表明:AS网络的稳定性随着路由器间建连距离的增大而表现出上升趋势,然而,若AS在地理上随机分布,则路由器建连距离对网络稳定性无明显影响。This paper analyzed how the AS＇s geographic locations and transmission distances affect on Internet＇s stability.In contrast to the traditional studies focusing on the future AS network which is based on nowadays,this paper emphasized particularly on the change of AS network＇s performance under the effect of the economic adjusting or the technology innovation to make adjusting measures and to lead the technological trend.A double-deck network model of geographic hypergraph and AS network was presented to simulate the geographic locations,which is not reflected in traditional models.The simulate results of our model show that Internet＇s stability ascends with the increase of transmission distances.However,if AS＇s geographic locations are random,the transmission distances has no obvious effects on Internet＇s stability.
