Traditional IP packet forwarding analyze

admin2022-08-02 78

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 （请作答此空）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 is （）. 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.A.anycastB.muticastC.broadcastD.unicast

选项 A.anycast
B.muticast
C.broadcast
D.unicast

答案 D

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。
