On estimation of the effective bandwidths in a system with regenerative input

The effective bandwidths (EB) of a communication system are considered. The EB guarantees that the stationary workload overflow/loss probability to exceed athreshold islimited by a(small)quantity. Itis shownhow tocalculate EB in a fluid queue fed by an input with the independent increments. Then, a fluid system with regenerative input is considered. Using heuristic arguments, an approximation of the limiting logarithmic exponential moment generating function of the input was deduced. Numerical simulations show a satisfactory accuracy of the approximation applied to a few systems with regenerative input.
