Market Report, "Core network power reduction will take holistic change", published

New Computer Technology research report from Ovum is now available from Fast Market Research
 
May 12, 2010 - PRLog -- For our second annual network power research project, we delved into near-term improvements that can be made at the sub-network element (NE), NE, and network (super-NE) level. Our initial network modeling, which focused on reducing power through more efficient gear and limiting IP transit traffic in the core, shows that power savings up to perhaps 50% of the present method of operation (PMO) are possible through architectural changes that are straightforward but still challenging to implement. Industry convergence on an "Energy Star"-like power metric and improvements in sub-wavelength grooming efficiency are critical. However, ultimately, just keeping power consumption flat given traffic growth projections will require more radical approaches.
