We implemented the VNF placement and scheduling solution presented in this work in a proof–of–concept NFV management and orchestration framework, named EmPOWER. Notice that, the prototype currently supports only wireless access networks based on the 802.11 family of standards and, as a consequence, the applications described in the next section target Enterprise WLANs and Campus networks scenarios. Nevertheless, as seen in the previous sections, the provisioning model does not make any assumption about the particular link–layer technology and can be as well applied to any kind of radio access network including OFDMA networks such as LTE and LTE–Advanced.
