The source Host A is going to send $10$KB $(10240$byte$)$ of data to the C$.$ Case C$.$ The $8$th segment is lost. All other transmissions are fine.

What is the total number of segments sent out from the source

$($including retransmissions$)?$

Answer:

D$.$ Case D$.$ The $10$th segment is lost. All other transmissions are fine.

What is the total number of segments sent out from the source

$($including retransmissions$)?$

Answer:

E$.$ Case E$.$ The $10$th segment is correctly received, but the ACK to the

$10$th segment is lost. Other transmissions are fine. What is the

total number of segments sent out from the source $($including

retransmissions$)$:

Answer:

note: Please fill in integer numbers only in the blanks

destination Host B over an established TCP connection, which has a

window size $($rwnd$)$ of $5$KB $(5120$byte$)$ and a maximum segment size

$($MSS$)$ of $1KB(1024$byte$).$ Assuming Go$-$Back$-$N is used in TCP$.$

Suppose there are errors in the transmissions. For each of the

following independent transmission error cases, please calculate the

total number of segments sent out from the source $($including

retransmissions$)$ in order to complete the transmissions of the $10KB$

data to the destination.

A$.$ Case A$.$ The $3$rd segment is corrupted. Other transmissions are

fine. What is the total number of segments sent out from the

source $($including retransmissions$)?$

Answer:

B$.$ Case B$.$ The $3$rd segment is correctly received, but the ACK to the

$3$rd segment is lost. Other transmissions are fine. What is the total

number of segments sent out from the source $($including

retransmissions$)?$
