Because of the high delay, there are often large Numbers of packets "in flight" waiting for acknowledgment at any given time.
高延迟会导致在任何给定时刻都有大量正在传送的包在等待应答。
When the congestion window on the sender is growing, it effectively doubles the number of packets in flight during the time it takes to send a packet and receive the acknowledgment back.
当发送方的拥塞窗口增大时，它会在发送出一个包和收到应答之间的时间内成倍地增加传输中的包的数目。
The time taken for this round-trip of request and acknowledgment determines the network's latency.
就是因为这种往返的要求和回应，导致了网络的延迟。
If the transmitting radio doesn't receive the acknowledgment in a certain amount of time, it will assume that the data was lost, and it will resend it.
如果无线发送装置在一定时间内收不到应答，就假定数据丢失，并且将重新发送数据。
That means that if you commit every single update in a loop, you will waste a lot of time just waiting for acknowledgment.
这就意味着如果我们总是每更新一次数据便提交一次，会因为确认信息而浪费许多时间。
Window size determines the amount of data that can be transmitted at one time before the destination responds with an acknowledgment.
视窗大小是表示在目的地端回应确认讯号之前可以一口气传送的资料量，这是就决定好了。
An acknowledgment isn't the end of the conversation. Being late all the time is rude.
自我承认不能作为对话的结束，每次都迟到就是不礼貌的表现。
If there was still no acknowledgment, it would be time for a shot across the battlewagon's bow.
如果还是没有应答，便要向战舰的船首上方发射炮火。
If an acknowledgment has not been received within a certain amount of time for a message that has been transmitted, the infrastructure automatically retransmits the message.
如果在特定一段时间内没有收到已传输之讯息的认可，则基础结构会自动重新传输该讯息。
If an acknowledgment is not received within a certain amount of time for a message that has been transmitted, the infrastructure automatically retransmits the message.
如果在传输消息后的一段确定时间内未收到确认，则基础结构将自动重新传输该消息。
If an acknowledgment is not received within a certain amount of time for a message that has been transmitted, the infrastructure automatically retransmits the message.
如果在传输消息后的一段确定时间内未收到确认，则基础结构将自动重新传输该消息。
