10 Thermal Management and Energy Efficiency

The network traffic in telecommunication industry has grown very rapidly every year since its inception. As projected, the network traffic demand will reach tens or hundreds of Tb/s in a couple of years. In response to the projected growth, new design and architecture are needed in order to face the power-density challenges in the next generation telecommunication networks. As pointed out by Vukovic [1], there are two aspects of these issues. One is the network architecture and another is telecommunication equipment design.
