       Network  virtualization  is  a  promising  technology  for  the 
       Internet   of  the  Future.  Nevertheless,  an  open  issue  in 
       virtualization  is to satisfy the control of resources in a way
       that energy savings are achieved. This paper introduces a model
       for  the  mapping  of  virtual networks onto network substrates
       which  aims  to  reduce  the  energy  consumption as well as to
       reduce  the  bandwidth  consumption.  This model is based on an
       integer  linear programming formulation and several parameters,
       corresponding   to   characteristic   of   real  networks,  are 
       considered.   The   trade-off   between  energy  and  bandwidth 
       consumption   is   analyzed   based   on  results  derived  via 
       simulation.
