Solves some inherent
maturity/scaling/performance issues
• Fully distributed data-plane
• VRS performs all routing and switching
functions on the compute node
preventing choke points and providing
consistent performance.
• Scalable control plane based on BGP
signaling – no central brain with lots of
messages
Provides advanced capabilities only
available with Nuage VSP
• Templated network designs
• Routing Flexibility: aligned per project or
inter-project, with or without Floating IP
• External access without gateways
• Service Chaining for FWs/ADCs/… (PBR)
• High-Throughput connectivity options to
non-virtualized servers
• Operational toolkit built around SAM-NV
• Enables hybrid cloud – Openstack can
coexist with other CMS

NTT & Telefonica held a joint session,
initiated by their ecosystem
collaboration, at ETSI NFV in Okinawa
EN RESUME
NFV is truly on the move
to production with major
investments on all
industry fronts moving
focus to operations
OpenStack is clearly the
preferred VIM (Virtualized
Infrastructure Manager)
by most telco’s worldwide
Gaps in OpenStack for
NFV are identified. Some
will be addressed in future
releases; some will
depend on the ambition of
OpenStack
Nuage Networks SDN
solution with its Neutron
plug-in provide a scalable
solution for networking
Collaboration between
vendors / telcos and open
ecosystem are important
to progress quickly
OpenStack is definitively
at the core of the NFV
transformation
