       Network  virtualization  is  a promising technique for building
       the  Internet  of  the  future  since  it  enables the low cost
       introduction  of  new  features  into network elements. An open
       issue  in  virtualization  is  how  to  search for an efficient
       mapping  of virtual network elements onto those of the existing
       physical network, also called the substrate network. Mapping is
       an  NP-hard  problem and existing solutions ignore various real
       network   characteristics  in  order  to  solve  problem  in  a 
       reasonable time frame. This paper introduces two new algorithms
       for  the  solution  of  the  mapping problem, both based on 0–1
       integer  programming,  for  the solution of the mapping problem
       which  consider a whole new set of network parameters not taken
       into  account  by  previous  proposals.  Simulation experiments
       confirm the efficiency of the proposed algorithms.
