停止等待协议和滑动窗口协议都是解决流量控制处理的技术。停止等待协议和滑动窗口协议的主要区别在于，在停止等待协议中，发送方发送一帧并等待接收方的确认，而在滑动窗口协议中，发送方发送一帧以上接收器并重新传输损坏或可疑的帧。
停止等待协议和滑动窗口协议的区别：
| S.NO | Stop-and-Wait Protocol | Sliding Window Protocol |
|---|---|---|
| 1. | In Stop-and-Wait Protocol, sender sends one frame and wait for acknowledgment from receiver side. | In sliding window protocol, sender sends more than one frame to the receiver side and re-transmits the frame(s) which is/are damaged or suspected. |
| 2. | Efficiency of Stop-and-Wait Protocol is worse. | Efficiency of sliding window protocol is better. |
| 3. | Sender window size of Stop-and-Wait Protocol is 1. | Sender window size of sliding window protocol is N. |
| 4. | Receiver window size of Stop-and-Wait Protocol is 1. | Receiver window size of sliding window protocol may be 1 or N. |
| 5. | In Stop-and-Wait Protocol, sorting is not necessary. | In sliding window protocol, sorting may be or may not be necessary. |
| 6. | Efficiency of Stop-and-Wait Protocol is
|
Efficiency of sliding window protocol is
|
| 7. | Stop-and-Wait Protocol is half duplex. | Sliding window protocol is full duplex. |
