  • 第11题：

    单选题
    A transport layer protocol has several responsibilities, One is to create a process-to-process (program-to-program) communication; TCP uses port (1) to accomplish this. Another responsibility of a transport layer protocol is to create a (2) and error-control mechanism at the transport level. TCP uses a sliding (3) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve (4) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends (5) of data to the transport layer. It is the responsibility of the transport layer at the sending station to make a connection with the receiver. 空白（1）处应选择（）
    A

    numbers

    B

    connection

    C

    diagrams

    D

    resources


    正确答案： A
    解析： 传输层协议有多个职责。一是创建进程到进程（程序到程序）的通信，由TCP使用端口号来完成；另一个职责是在传输层创建流和差错控制机制。TCP利用滑动窗口协议来实现流控制。它使用确认分组、超时、重传机制来完成差错控制。传输层也负责为应用程序提供连接机制，应用程序将数据流发送到传输层，发送端的传输层负责建立于接收端之间的连接。

Any authentication scheme used by the transport protocol may be used in addition to BGP's own （ ）mechanisms. The error notification mechanism used in BGP （ ）that the transport protocol supports a “graceful” close, i.e., that all outstanding data will be delivered （ ）the connection is closed.

    A.synchronization

    答案：D
    解析：
    bgp通过可靠的传输协议运行。这样就不需要实现显式的更新分段、重新传输，确认和排序。使用的任何身份验证方案除了bgp自己的身份验证机制之外，还可以使用传输协议的验证方案。bgp中采用的错误通知机制，假定传输协议支持“正常”关闭，也就是说，所有未完成的数据将在连接关闭之前交付。
