Abstract

Network virtualization has been pointed out as a promising technique to tackle Internet's current ossification and to mitigate sustainability issues related to energy consumption. A critical issue is the virtual network embedding (VNE), due to the NP-hard nature of the problem. Thus, several heuristics have been proposed aiming to achieve efficient allocations. In this paper, we extend the VNE problem to consider dependability and energy consumption issues, utilizing an approach based on GRASP metaheuristic. Experimental results demonstrate energy savings obtained with the proposed approach over representative VNE techniques. The results also present a trade-off between energy consumption, availability and cost.

可靠虚拟网络的能量感知映射

网络虚拟化被认为是一种很有前途的技术，可以解决互联网目前的僵化问题，并减轻与能源消耗有关的可持续性问题。由于问题的NP-hard性质，一个关键问题是虚拟网络嵌入(VNE)。因此，提出了几种旨在实现有效分配的启发式方法。在本文中，我们利用一种基于GRASP元启发式的方法，将虚拟网络问题扩展到考虑可靠性和能耗问题。实验结果表明，该方法比典型的VNE技术节能。结果还显示了能源消耗、可用性和成本之间的权衡。
