acknowledgement frame

基本解釋

If the sender receives a positive acknowledgement about a frame, it knows the frame has arrived safely.
如果發(fā)送端收到了有關(guān)幀的肯定應(yīng)答，它就知道發(fā)送的幀已經(jīng) 安全到達(dá)。
On the other hand, a negative acknowledgement means that something has gone wrong, and the frame must be transmitted again.
另一方面，否定應(yīng)答則意味著出現(xiàn)了某種錯(cuò)誤，應(yīng)該重新發(fā)送出錯(cuò)的幀。
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.
當(dāng)網(wǎng)絡(luò)需要預(yù)防擁塞發(fā)生時(shí)，標(biāo)記將以最快的速度到達(dá) 接收端，并且被確認(rèn)幀帶回到發(fā)送端。
