Problem $8$: Suppose station A sends information to station B on a data link that operates at a speed of $10Mbps,$ and that that station B has a $1-$Megabit buffer to receive information from A$.$ Suppose that the application at station B reads information from the receive buffer at a rate of $1Mbps.$ Assuming that station A has an unlimited amount of information to send, sketch the sequence of transfers on the data link if Stop$-$and$-$Wait ARQ is used to prevent buffer overflow at station B$.$ Consider the following cases: $5$Ketch it$-$

a$.$ One$-$way propagation delay is $1$ microsecond.

b$.$ One$-$way propagation delay is $1ms.$

c$.$ One$-$way propagation delay is $100ms.$
