Then I introduce the algorithm of automatic repeat request and calculate the utilization ratio of the link.
接着又介绍了自动请求重传算法并计算了通常情况下的链路利用率。
Automatic repeat request (ARQ) schemes and transport control protocol (TCP) are often used as error-control techniques at the link layer and at the transport layer, respectively.
自动重传请求(ARQ)和传输控制协议(TCP)经常被分别用作链路层和传输层的错误控制机制。
