Centralized Radio Access Network (C-RAN) is a promising mobile network architecture to face the increasing mobile traffic demand. In this paper, we propose a detailed model to evaluate the statistical multiplexing gain achieved through C-RAN baseband pooling, and based on this model we can perform a cost analysis taking into consideration different geographical type areas (geotypes). We show the influence...
Energy-efficiency has been widely recognized as an important target in the management of optical wavelength division multiplexing networks. A very promising power management strategy consists in putting unused transponders into a low-power state, called idle or sleep state, or even in turning them off. However, in such scenario, it should be also guaranteed that high-priority traffic, which requires...
We use an analytical formulation based on Markov chains to evaluate blocking and energy-saving performance of a Wavelength Division Multiplexing (WDM) network with transponder power management. We consider three power modes for transponders, i.e., powered-on (ON), idle (sleep) or powered-off (OFF). To guarantee fast provisioning to high priority (e.g., real time) connections, we assume that some idle...
