当网络需要预防拥塞发生时，标记将以最快的速度到达接收端，并且被确认帧带回到发送端。

When the network needs to control the congestion, the signal will be delivered to the receiver at the fast speed, and was brought to the initiator by the acknowledgement frame.

我质疑到读者能否确认客户端的数据帧和服务器端的数据帧是对称的，并且由相同的数据帧实现。

I challenge the reader to confirm that the client side framing and the server side framing are symmetric and implement the same data framing!

对于WLAN工作站与接入点之间的通信，帧确认会降低带宽，使用同一接入点的其他工作站的数量也会带来同样影响。

For communication between a WLAN station and an access point, frame acknowledgments decrease the bandwidth, as do the number of other stations using the same access point.
