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.
