Bufferless fluid flow model (bffm) is widely used in the literature for cell loss analysis. In this paper, we propose an efficient and effective means of investigating cell loss in the bffm. We define the cell loss rate function (clrf) and use it to characterize the cell loss of traffic sources in the bffm. Properties of clrf are discussed. These properties enable us to decompose the complex analysis of the multiplexing of several traffic sources into the simpler analysis of the individual sources. A cell loss upper bound for heterogeneous ON–OFF sources is proposed using clrf. The proposed cell loss upper bound is tighter than that proposed in previous literature. A connection admission control (CAC) scheme using online measurements is designed based on the cell loss upper bound. Extensive simulations are carried out to study the performance of the CAC scheme. Simulation results indicate that the proposed CAC scheme is time-efficient, can ensure QoS guarantee, and is capable of achieving high network utilization.
