Self doubt

Question

What does this 2nd points means wrt TCP window.

We need not send complete window everytime..but we  send complete window data once at a time. Right?

Is it something related to PUSH flag

Comments

There could be few reasons.

• The receiver is advertising a lesser amount of window.
• The capacity of the channel is less i.e. to avoid n/w congestion 

Answer 1

It means that initially the Sender sends the data equal to the Sliding window size and keeps increasing exponentially. It will never send the entire data at once, voilating flow control and congestion control.
