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.
