As the demand for new Internet services, such as 3-D online gaming, video conferencing and learning, video telephony and downloading, and high-definition video-on-demand, becomes more widespread, the amount of electricity used by servers, communication devices, and Internet infrastructure continue to be a major concern. Various studies show that in 2005 the total energy used by data centers (including their associated infrastructure) was about 1.5% of the total U.S. electricity consumption. This is equivalent to the electricity consumed by six million homes or about three billion dollars and eight million tons of CO2emission. It is estimated that the annual IP traffic in 2012 will be about eight times larger than its level in 2005, surging the total energy cost to about 24 billion dollars.
The objective of this research is to examine and compare the power consumption between optical cross-connect equipment based on electrical and photonic matrix switching. We also like to study modular optical node architecture that is capable of offering energy-awareness in QoS-enabled traffic grooming.
