In an access network, the token bucket algorithm is used for access

In an access network, the token bucket algorithm is used for access control. In every time step, the probability of one packet arrival is 0.5, the probability of one token arrival is also 0.5. The token buffer size B = 2, and the packet buffer size is B, = 2. (a) Find the packet loss rate N.(lost). (b) Find the token throughput (average number of tokens leave the system per time step). [Think:] what happens if the token arrival probability per slot is equal to 0.5/(k + 1) where k is the number of tokens in the token buffer?
