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 non reserved traffic?
(c) Eventually, the receivers on these flows will request that their reservations be renewed. Give a scenario in which these requests are denied.
