This document describes open research challenges for network
virtualization. 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.
