Abstract: Energy consumption, as well as carbon emission, from ICT is growing extremely. Such a growth trend needs to be facilitated by the creation of an energy-efficient and flexible network as an effort in developing the future internet. Recently, network virtualization (NV) has emerged as promising paradigm for data centers as the infrastructure for cloud computing. Network virtualization allows flexible sharing of physical network resources by multiple users. In a realistic NV context, virtual network requests come to the system continuously and dynamically, which affects the embedding efficiency. In this paper, we propose an online time window-based embedding strategy which focuses on saving energy consumption of a network. The experimental results show that the proposed method works efficiently in both energy consumption and resource utilization. |
Keywords and phrases: virtual network embedding, energy efficiency. |
