Models for Evaluating Power Saving Techniques in Flexible Optical Access Networks

Increased use of power in telecommunication networks has not only increased the cost of operation but also increased the carbon footprint and the environmental hazards. In this paper, we propose models for evaluating power saving techniques in flexible passive optical access networks. In addition, the power model of their sleep modes are proposed and are extended to analyse the power saving potentials of state-of-art dynamic bandwidth allocation (DBA) algorithms like sleep mode aware (SMA) and hybrid sleep mode aware (HSMA).
