We consider I fluid queues in parallel. Each fluid queue has a deterministi
c inflow with a constant rate. At a random instant subject to a Poisson pro
cess, random amounts of fluids are simultaneously reduced. The requested am
ounts for the reduction are subject to a general I-dimensional distribution
. The queues with inventories that are smaller than the requests are emptie
d. Stochastic upper bounds are considered for the stationary distribution o
f the joint buffer contents. Our major interest is in finding exponential p
roduct-form bounds, which turn out to have the appropriate decay rates with
respect to certain linear combinations of buffer contents.
