Abstract :
In this paper, we study bandwidth management of a wireless/optical based access/metro network in support of voice and data services. For voice services, we use a finite state Markov Chain to estimate the blocking probability of voice circuits over an Adaptive modulation and coding wireless channel, as a function of the channel parameters. For data services, we evaluate a rate matching and a buffer level control schemes to adjust optical provisioned bandwidth with the wireless channel capacity. We use analysis and event-driven simulation to substantiate our findings.
