Abstract

改进的随机互连的紧凑路由方案

随机拓扑已经成为设计互联网络的一种越来越有利的方法，asitcanprovideacombinationoflowlatencyandincrementalnetworkgrowththatcould notbeprovidedbythetraditionalrigidtopologies。However，thecommonshortest-pathroutingina randominterconnectposesascalabilityproblem，foritrequiresglobalnetworkinfotomakerouting decisionsandso，theroutingtablesize(RTS)canbeverylarge。Therefore，thismanuscriptwould旨在重新审视基于地标的紧凑路由的著名研究领域，并改进theuniversalroutingschemesforthespecificcaseofrandominterconnects。Itwouldproposenew landmark-basedcompactroutingschemes，using2heuristictechniquestoselectlandmarksthatare evenlyspaced，whichwouldreducetheRTSinthewell-knownThorupandZwick 'sschemebyup to18%andproduceashorteraveragepathlength。关键词:紧凑路由，数据中心网络，互连网络，基于地标的路由，随机互连，随机网络，路由算法，路由表大小
