Anycast routing for carbon footprint reduction in WDM hybrid power networks with data centers

The paper focuses on dynamic resource provisioning which minimizes carbon footprint in optical networks. The main contribution of this paper consists of three anycast routing strategies aimed at reducing greenhouse gases emission by processing energy-intensive requests in data centers powered from renewable energy sources. The proposed strategies were compared with reference approaches with respect to CO₂ emission and their impact on network performance. It is shown that they are able to significantly reduce greenhouse gases emission and, simultaneously, improve network performance.
