Question: (a) Redraw Fig. for the case in which qr = 1/m and qa = 1/m?.
(b) Find the departure rate (i.e., Psucc) in the fully backlogged case n = m.
(c) Note that there is no unstable equilibrium or undesired stable point in this case and show (graphically) that this holds true for any value of qa.
(d) Solve numerically (using qa = 1/m?) for the value of G at which the stable point occurs.
(e) Find n/m at the stable point. Note that this is the fraction of the arriving packets that are not accepted by the system at this typical point.
