  • 第1题：

    Traditional network layer packet forwarding relies on the information provided by network layer （） protocols, or static routing, to make an independent （）decision at each hop within the network. The forwarding （）is based solely on the destination （本题）IP address. All packets for the same destination follow the same path across the network if no other equal-cost paths exist. Whenever a router has two equal-cost （）toward a destination, the packets toward the destination might take one or both of them, resulting in some degree of load sharing.

    A.paths
    B.distance
    C.speed

    A.services
    B. Users
    C. networks
    D.structures


    答案：A
    解析：
    在网络中提供QoS的差分服务应用了一种很小的明确定义的构建模块集合来建立各种服务。它的目的就是利用IPv4头部中的服务类型(ToS )和IPv6中的通信类型定义不同的服务字节(DS)，而且在每一个网络节点用分组的标准化DS字节来表示它接收到一种特殊的转发处理规则或每跳的行为(PHB)。差分服务体系结构提供了一种框架，使得可以为用户提供一定范围的网络服务，每种服务都有不同的性能。用户只要给分组的差分服务码点(DSCP)字段赋予特殊的值，就可以按照各个分组的需要选择性能级别。这个值说明了在服务提供的网络中给予分组的PHB 。
