Another responsibility of a transport layer protocol is to create a ( ) and error-control mechanism at the transport level. TCP uses a sliding ( ) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve ( ) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends ( ) of data to the transport layer.

传输层协议有多种作用。其一是产生进程(或程序)之间的通信,TCP使用端口号来实现这个功能。传输层协议的另一个作用是形成传输层的流量和差错控制机制,TCP使用滑动窗口协议来进行流量控制,并且使用应答分组、超时机制和重传技术来实现差错控制功能。传输层还要为应用程序建立连接,应用程序向传输层发送数据流,发送方的传输层就与接收方的传输层建立对应的连接。
