    The diffserv approach to providing QoS in networks employs a small,well-defined set of building blocks from which you can build a variety of( ).Its aim is to define the differentiated services(DS)byte,the Type of Service(ToS)byte from the Internet Protocol Version 4( )and the Traffic Class byte from IP Version 6,and mark the standardized DS byte of the packet such that it receives a particular forwarding treatment,or per- hop behavior(PHB),at each network node.The diffserv architecture provides a( )within which service providers can offer customers a range of network services,each differentiated based on performance.A customer can choose the(________ )level needed on a packet-by-packet basis by simply marking the packet's Differentiated Services Code Point(DSCP)field to a specific value.This ( ) specifies the PHB given to the packet within the service provider network。横线处应选（ ）


    A.performance
    B. Secure
    C. privacy
    D.data


    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 。
