Abstract: Network functions virtualization (NFV) is a contemporary theme in telecommunication industry in the recent past and It is the main instrument of major transformational changes in the modern days network. NFV gives flexibility to network service and reduce enormous amount of time to deploy new network services without any hurdles. It can be achieved through various recent technologies such as cloud computing, Industry Standard High Volume Servers, Software Defined Networking (SDN).Mobile network highly exploited NFV because of cost effective. In this study, we proposed combination of window based VN embedding algorithm with Simple Lazy Facility Location to compute the optimal virtual network placement on radio access network. Comparing with the SLFL algorithm and ILP algorithm, the average link utilization is well connected. It can be noticed that approximately 4 -5 per cent increase in link utilization compared with existing algorithm.
