  • 第4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(请作答此空)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 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.routing
    B.forwarding
    C.transmission
    D.management

    答案:A
    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。

    A router receives a packet on interface 172.16.45.66/26. The source IP of the packet is 172.16.45.127/26 and the destination is 172.16.46.191/26.How will the router handle the packet?()
    A

    The destination is a host on another subnet, so the router will not forward the packet.

    B

    The destination is a host on the same subnet, so the router will forward the packet.

    C

    The destination is a broadcast address, so the router will not forward the packet.

    D

    The destination is a network address, so the router will forward the packet.

  • 第15题:

    Anytime a host or a router has an IP datagram to send to another host or router, it has the( )address of the receiver. This address is obtained from the DNS if the sender is the host or it is found in a routing table if the sender is a router. But the IP data gram must be( ) in a frame to be able to pass through the physical network. This means that the sender needs the ( )address of the receiver. The host or the router sends an ARP query packet. The packet includes the physical and IP addresses of the sender and the IP address of the receiver. Because the sender does not know the physical address of the receiver, the query is( ) over the network.Every host or router on the network receives and processes the ARP query packet, but only the intended recipient recognizes its IP address and sends back an ARP response packet.The response packet contains the recipient's IP and physical addresses. The packet is(请作答此空) directly to the inquirer by using the physical address received in the query packet.

    A. multicast
    B. unicast
    C. broadcast
    D. multiple unicast

    答案:B
    解析:
    任何时候主机或路由器要发送 IP 数据报发送给另一主机或路由器时,都需要知道接收方的逻辑地址。发送主机从 DNS 获得该地址,发送路由器则在路由表中找到该地址。但 IP 数据报必须封装在帧中才能通过物理网络。这意味着发送者需要知道接收者的物理地址。主机或路由器需发送 ARP 查询报文,该报文分组包含发送者的物理地址和 IP 地址及接收者的 IP 地址。这是因为送者不知道接收者的物理地址,所以需在全网广播报文。网络上的每个主机或路由器都能接收并处理该 ARP 查询报文,但只有预期的接收者识别其 IP 地址并响应该 ARP 报文。响应报文包含接收者的 IP 地址和物理地址。包含了接收者物理地址的响应报文分组通过单播的方式直接发送给发送者。
