Stop$-$and$-$Wait vs$.$ Pipelined Protocol

Calculate the following questions to get a total credits of $5$ pts

Suppose two hosts, A and B$,$ are connected with an RTT of $100$ ms and a bottleneck

link rate of $30$ Mbps$.$ Suppose that A sends data message to B $($i$.$e$.,$ the communication

is unidirectional$).$ Assume that packets are $1500-$bytes long $($including headers$),$ and no

queuing delays in the routers.

a$)(1$ pt$)$ What is the maximum throughput between A and B $($estimated value is fine$)?$

b$)(2$ pts$)$ In a standard stop$-$and$-$wait protocol, what is the utilization of A$?$

$4$

c$)(2$ pts$)$ Suppose we use a pipelined protocol where n packets are allowed to be sent

back$-$to$-$back, what is the utilization of A$?$
