  • 第13题：

    The operation of the Internet is closely monitored by the routers. When something unexpected occurs, the event will be reported by the protocol(73)。

    A．IGMP

    B．ICMP

    C．IP

    D．OSPF


    正确答案：B
    解析：本题考查一些常用的网络协议。下面我们来看看选项中这些协议及作用。IGMP(Internet组管理协议)是因特网协议家族中的一个组播协议，用于IP主机向任一个直接相邻的路由器报告它们的组成员情况。ICMP(Internet控制消息协议)主要用于在主机与路由器之间传递控制信息，包括报告错误、交换受限控制和状态信息等。当遇到IP数据无法访问目标、IP路由器无法按当前的传输速率转发数据包等情况时，会自动发送ICMP消息。IP(网际互连协议)是能使连接到网上的所有计算机网络实现相互通信的一套规则，规定了计算机在因特网上进行通信时应当遵守的规则。OSPF(开放式最短路径优先)是链路状态路由协议。参考译文：在因特网上的操作受到路由器的紧密监控，当网络中一些异常的事件发生时，ICMP协议将报告这些异常。
