Once the sending fails, an er

In recent months, I have interviewed a lot of programmers. The better names are software engineers and even senior software engineers. I usually ask related questions about the subject's expertise.

, congestion control: When the network congestion, reduce the transmission of data.Second, sliding windowThe above general said TCP guarantees reliable transmission mechanism, the following is how to use sliding window to achieve.Why use sliding windowsBecause the sender expects to continue sending other segments of the message before receiving confirmation.
