Problem $5(10$ points$)$: A TCP machine is sending the maximum window size of bytes over a $200$

$M$b$/$s channel that has a $30$msec one$-$way delay.

a$)(4$ points$)$ Compute the average throughput achieved.

b$)(3$ points$)$ Compute the line efficiency.

c$)(3$ points$)$ Compute the needed window size in bytes to fill in the pipe between sender and

receiver?
