摘要/Abstract

摘要： 建立在物理设备集中且以云平台收益为目标的虚拟网络映射技术在企业级网络中存在不适应性，本文提出了有位置限制的企业级虚拟网络映射能源优化策略（EL-VNE）.首先，采用复数理论将计算能力和带宽能力归一到单个节点处，减少了映射次数.其次，提出了EL-VNE模型，包括能源消耗，资源消耗，位置限制等数学描述，并证明其属于NP完全问题.最后，提出了启发式算法求解EL-VNE的最佳解空间，确定虚拟映射方案，达到优化能耗的目的.相比于EAD和GLC等算法，EL-VNE在映射和运行过程中能进一步降低能源消耗且有更好的性能表现.

关键词: 虚拟网络映射, 企业级网络, 能源消耗优化, 位置限制

Abstract: The studied technologies which were based on centralized physical devices and targeted on benefit optimization could not be applied in the enterprise network.To solve this problem,a cost optimization strategy based on location constrain(EL-VNE) was proposed for virtual network embedding in the enterprise network.Firstly,the computing and bandwidth capabilities were unified to a single node by using the complex theory,which decreased embedding times.Secondly,the EL-VNE model was presented and composed by mathematical descriptions about energy consumption,resource consumption and location constrain,which was proved to be NP-completed.Finally,heuristic algorithms were designed to find the solution of EL-VNE and then the embedding scheme with energy optimization was obtained.Compared with algorithms such as EAD and GLC,EL-VNE saves energy consumption in the process of embedding and running,and has better performance.

Key words: virtual network embedding, enterprise network, energy costs optimization, location constrain
