A node in a computer network can be modeled as an $\frac{M}{M}\frac{?}{1}$ queue. The capacity of the line out

of the node is $1[$Mbps$],$ and there are $10[$Kbits$]$ per message. Under certain conditions it is

known that the average of $19$ messages are stored in the system $($storage buffer and output line$)$

a$)$ What is the traffic intensity?

b$)$ Under these same conditions, what is the input rate?

c$)$ What is the total average time delay through the system?

d$)$ What is the average number of messages stored in the buffer?

e$)$ What is the average queueing delay?
