Green networking, by making the network more energy efficient and helping reduce environmental impact, is receiving more and more attraction for sustainable ICT. In this paper, we propose a new green approach for Named Data Networking (NDN) where content requests and caching perform towards green content delivery. We design a forwarding and caching strategy, where we first define the greenness of nodes, a quantitative metric for measuring the environmental footprint of the network, based on which we identify corresponding green paths and encourage traffic to aggregate on green paths powered by more eco-friendly renewable energy. We validate our approach with a variety of simulations using real network topology and renewable energy datasets from the US, and the results show that applying the proposed green NDN achieves significant ecofriendly gains.
