Traditional IP packet forwarding analyze

最全题库2022-08-02 50

问题 Traditional IP packet forwarding analyzes the （　　）IP address contained in the network layer header of each packet as the packet travels from its source to its final destination. A router analyzes the destination IP address independently at each hop in the network. Dynamic （　　）protocols or static configuration builds the database needed to analyze the destination IP address （the routing table）.The process of implementing traditional IP routing also is called hop-by-hop destination-based （　　）routing. Although successful，and obviously widely deployed，certain restrictions，which have been realized for some time，exist for this method of packet forwarding that diminish its （　　）. New techniques are therefore required to address and expand the functionality of an IP-based network infrastructure.This first chapter concentrates on identifying these restrictions and presents a new archiecture，known as multiprotocol （　　）switching，that provides solutions some of these restrictions.问题1选项A.datagramB.destinationC.connectionD.service问题2选项A.routingB.forwardingC.transmissionD.management问题3选项A.anycastB.muticastC.broadcastD.unicast问题4选项A.reliabilityB.flexibilityC.stabilityD.capability问题5选项A.costB.castC.markD.label

答案 BADBD

解析传统的IP数据包转发分析目的IP地址，该地址包含在每个从源到最终目的地的网络层数据包的头部。一个路由器的分析目的IP地址，该地址独立在网络中的每跳。动态路由协议或静态配置构建数据库，该数据数据库需要分析目的IP地址（路由表）。实施传统的IP路由的过程也叫作基于目的地的逐条单播路由。虽然成功而且明显得广泛部署，并实现了一段时间，但是必然有某些限制，这种数据包转发方法的存在是减少了灵活性。新技术是因此需要地址和扩展一个基于ip的网络基础设施的功能。第一章集中在识别一种新的架构的限制条件和反馈，该架构众所周知是多协议标签交换，它为其中的一些限制条件提供解决方案。
