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 targets 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 WLAN and Campus network 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.
