Summary:The bufferless fluid flow model (BFFM) is often used in the
literature for loss performance analysis. We propose an efficient and
effective means of investigating cell loss using the BFFM. We define the
cell loss rate function (CLRF) and use it to characterize the loss
performance of traffic sources in the BFFM. Stochastic ordering theory
is used to study the CLRF. The introduction of the stochastic ordering
theory not only simplifies the theoretical analysis but also makes it
possible to extend the scope of applications and theoretical analysis
presented. A cell loss upper bound for heterogeneous on-off sources is
proposed. The proposed cell loss upper bound is tighter than those
previously proposed in the literature. A connection admission control
(CAC) scheme using online measurements is designed based on the cell
loss upper bound. Extensive simulation is carried out to study the
performance of the CAC scheme. Particular attention is paid to the
impact of inaccuracies in user-declared traffic parameters on the
performance of the CAC scheme. Simulation results indicate that the
proposed CAC scheme can ensure QoS guarantee, is robust to inaccuracies
in declared traffic parameters, and is capable of achieving high link
utilization
