It is often stated that NFV imposes additional requirements on the networking
architecture and feature set of the underlying NFVI beyond those of data center
networking. For instance, the NFVI needs to establish and manage connectivity

It is an ongoing debate how well the current OpenStack networking architecture
can meet the additional requirements of NFV networking. Hence, a thorough
analysis of NFV networking requirements and their relation to the OpenStack
