Diary 0601: The Energy Efficiency of Network.(Core Network, Access Network and Data Center)

It is a critical issue about energy efficiency of ICT. It is more easily to save energy by improving the network components and computing devices.

But there are some opportunities to save energy from the viewpoint of network, including core network, access network and the data center.

In the core network, typically, we can save energy by turning off some line card, traffic grooming, and other new scheme to design the network.

In the Data center, by analyzing the energy consumption in different part of holistic data center, we can improve energy efficiency by enhance the 

cooling system, by change the site of data center near to the power plant and shut down some unused packs.

In the access network, it should be more opportunities to save energy, because the utilization in this area is lowest as 15%. We can improve the 

energy efficiency by reshaping the traffic inter-ONUs, we can redesign the protocol to save energy.

In one world, from the perspective of network, we can scheduling the traffic, redesign the network to shut down some resource.
