    ●One ofthe main resposibilities ofICMP is to report (71). Although technology has produced increasingly reliable transmission media, errors still exist and must be handled. IP is an (72) protocol. This means that error checking and error control are not a concem ofIP.ICMP was designed, in part, to compensate for this shortcoming. Howerver, ICMP does not _(73) errors, it simply reports them. Error correction is left to the higher-level potocols. Error messages are always sent to the original__(74) because the only information available in the datagram about the route is the source and destination lP addresses. ICMP uses the source IP address to send the error massage to the source ofthe(75) .

    答案：A
    解析：

    在低速网络中，通常采用碰到拥塞时，通过向源端反映使其降低发送速率。而在告诉网络中，这种方式将会恶化，因为在发送通告和通告到达之间会有成千上万的其它数据包到达。在ATM网络中，主要采用允许控制来避免拥塞，当有一台主机要建立一条新的虚连接时，它必须描述它所需的流量和服务等级。
