A survey on environmental backbone design and implementation

Communication networks are becoming more essential for our daily life and critically important for industry and governments. The intense growth in the backbone traffic implies an increment on the power demands of the network equipment. This power usage has a significant negative effect on the environment. In this paper, some ideas are exposed and discussed in order to make backbone communication network more environmentally friendly. In addition the scheme of a potential model is introduced to be able to evaluate the emissions of a network during its life time.
