Abstract
The authors analyse the multiplexing of a large number of independent and homogenous on-off traffic sources into a single packet switched buffer: a possible model of VoIP. It is shown how a previously developed formula for queues can be applied to this system, allowing accurate calculation of the buffer overflow probability via the burst-scale decay rate of the buffer state probabilities. Numerical results comparing the expression with simulation and with other approximations shows that the approach gives superior accuracy, with equivalent complexity
