A TCP sender receives an ACK with an advertised window of $0$. What is the sender's appropriate action to determine when the receiver's buffer has space again?
Question 2
In TCP flow control, if the receiver's application is consuming data at a rate significantly slower than the network's capacity, how does this impact the sender's transmission rate?
Question 3
Consider a TCP connection where the receiver has a buffer of $6000$ bytes. It has received $4000$ bytes of data, and its application has consumed $2500$ bytes. What is the current advertised window (RWND) that the receiver will send to the sender?
Question 4
Which of the following scenarios would most directly lead to a sustained decrease in the TCP advertised window size?
Question 5
What is the fundamental difference in purpose between TCP flow control and TCP congestion control?
