Network virtualization is following a similar path as previously taken by cloud computing. Specifically, cloud computing popularized migration of computing functions (e.g., applications) and storage from local, dedicated, physical resources to remote virtual functions accessible through the Internet. In a similar manner, network virtualization is encouraging migration of networking functions from dedicated physical hardware nodes to a virtualized pool of resources. However, network virtualization can be considered to be a more complex problem than cloud computing as it not only involves virtualization of computing and storage functions but also involves abstraction of the network itself. This document describes current research and engineering challenges in network virtualization including the guarantee of quality of service, performance improvement, support for multiple domains, network slicing, service composition, device virtualization, privacy and security, separation of control concerns, network function placement, and testing. In addition, some proposals are made for new activities in the IETF and IRTF that could address some of these challenges. This document is a product of the Network Function Virtualization Research Group (NFVRG). This document is a product of the Network Function Virtualization of the IRTF.
