Energy consumption and the associated costs constitute a crucial issue concerning the design and operation of data networks and data centers. Energy-awareness is required in all levels, ranging from physical layer to algorithms, protocols and applications. Architecture-wise, a promising solution for tackling the increasing energy requirements is the deployment of optics at both long and shorter distances,...
The evolution of novel access networks is dominated by two major changes: first, an increasing convergence of fixed optical and mobile wireless access networks (driven by the industry interested in mutualizing infrastructure); and secondly, a surge in video traffic (expected to represent 80 percent of all consumer Internet traffic in 2019). This motivates the introduction of video delivery optimization...
The impact of broadband access network migration on the power and energy consumption is studied by establishing an analytic migration model. The results show that power-aware strategies are necessary for efficient broadband access network migration.
