29. The transmission schedule (shown below) for a given flow is for each second the number of packets sent between that time and the following second. The flow must stay within the bounds of a token bucket filter. Find the necessary bucket depth D as a function of token rate r. Note that r takes only positive integer values. Assume the bucket is initially full. 30. Suppose an RSVP router suddenly loses its reservation state, but otherwise remains running. (a) What will happen to the existing reserved flows if the router handles reserved and nonreserved flows via a single FIFO queue? (b) What might happen to the existing reserved flows if the router used weighted fair queuing to segregate reserved and nonreserved traffic? (c) Eventually the receivers on these flows will request that their reservations be renewed. Give a scenario in which these requests are denied
