1. Introduction

   Over the last few years, Network Functions Virtualization (NFV) [ETSI-NFV-ARCH] 
   has been becoming one of the most promising study areas for developing new 
   computer network technologies. NFV poses a novel way to develop network services,
   by using software and virtualization aiming the replacement of proprietary hardware
   appliances that run network functions. In NFV, these services, called Virtualized 
   Network Functions (VNFs), are implemented through software and deployed in Virtual 
   Machines (VMs), allowing new and efficient ways of network deployment. NFV allows 
   to manage and customize network services according to business needs, enabling 
   tremendous cost savings and more agility to serve the daily changes that networks 
   are susceptible. In addition, network function virtualization (NFV) is undoubtedly 
   one of the key technologies needed to create a smooth path for migration.
        
        For network management, Software Defined Networking (SDN) [SDN-Survey] aims to 
        manage the network and the functions provided by separating the control plane 
        from the data plane. The SDN controller(s) possess a global view of the network 
        and can therefore simplify the network management as compared to the traditional
