Use Go$-$back$-$N ARQ. Each frame is $200$ bits long. The sender will send $10000$ bits

over a $100$kbps link with a distance between sender and receiver of $100$km and link propagation

speed of $2$x$108$m$/$s$.$ Assume no frame loss or damage. Ignore transmission time for ACK.

a$)$ How many frames in total for $10000$ bits?

b$)$ Assume the field for the sequence number has k$=3$ bits. What is the sequence number for the

last frame?

c$)$ How long does it take to complete the transmission of these $10000$ bits $?($Hint: what is the

maximum window size for Go$-$back$-$N ARQ? Use the most efficient way of transmission:

transmitting the maximum number of frames in a row, i$.$e$.,$ the maximum window size, and

waiting for one ACK$)$
