WirelessnetworksareevolvingintowirelessIP(InternetProtocol)networksto overcomethelimitationsoftraditionalcircuit-switchedwirelessnetworks.Wireless IPnetworksaremoresuitableforsupportingtherapidlygrowingmobiledataand multimediaapplications.IPtechnologiesbringthegloballysuccessfulInternet servicecreationandofferingparadigmtowirelessnetworks,bringingthevastarray ofInternetservicestomobileusersandprovidingasuccessfulplatformforfostering futuremobileservices.IP-basedprotocols,whichareindependentoftheunderlying radiotechnologies,arealsobettersuitedforsupportingseamlessservicesover heterogeneousradiotechnologiesandforachievingglobalroaming.

SeveralmajoreffortshaveemergedtodefineglobalstandardsforwirelessIP networks.Thetwomostinfluentialstandardsbodiesare3GPP(ThirdGeneration PartnershipProject)and3GPP2(ThirdGenerationPartnershipProject2).Different standardseffortshavebeentakingsignificantlydifferentapproaches,whichleadto differentarchitecturesanddifferentmigrationpathstowardfuturewirelessIP xi networks.ThisbookprovidesinsightsintocriticalissuesinwirelessIPnetworking, thoroughlyillustratesthestandardsandnetworkarchitecturesdefinedbyleading standardsbodiessuchas3GPPand3GPP2,anddiscussesindetailprotocols andtechniquesinfourmajortechnicalareas:signaling,mobility,security,and QoS.

tomcat6.x源码编译依赖的jar包
tomcat6.x源码编译时需要依赖的所有JAR包:包括ant.jar、jaxrpc.jar、org.eclipse.jdt.core_3.8.3.v20130121-145325.jar、wsdl4j-1.5.1.jar。编译tomcat源码时把这些JAR包引入就可以了,亲测不报错,完全可用。 tomcat源码调试步骤: 1.到官网下载源码,解压 2.在根目录下把build.properties.default文件名去掉后面的.default 3.把该文件中的base.path值改成你自己指定的目录 4.在根目录中运行ant download,成功后再运行ant 5.新建JAVA Project,把根目录中的Java、test复制到工程中,并设置成build path, 6.引入我提供的JAR包,编译 7.找到Bootstrap.java,debug as>debug configurations>VM arguments:输入-Dcatalina.base="(改成你自己的)E:\apache-tomcat-6.0.37-src\output\buildoutput\build" 8.OK.
