Armonization of Italian research networks started in 1986 with initial funding from Ministry of University and Research. Non-for-profit Association fouded by CNR, ENEA, INFN e Fondazione CRUI (representing all the State Universities) under the aegis of the Ministry of Education, University and Research (MIUR) in 2002 Directly funded by the its members and connected entities (no public funding)
Consortium GARR Founding members

Why SDN/NFV in NRENs
- NRENs are large carriers, with customers of very large size and carrier grade requirements for operation
- The users' requirements imply
- MultiGigabit capacity, packet based
- Virtual Private Networking
- end-to-end traffic for collaborations worldwide (multidomain)
- Continuous production and exchange of information
- High performance computing and storage
Any technology which will decrease network costs, simplify control/management planes and simplify services, is welcome...

The ICT landscape evolution
- MPLS, BGP got protocol extensions for multidomain transport, carrier grade and are now a mature technologies, widely used
- IP (packets), TCP, UDP and Ethernet are the standard data transport element (plus some Infiniband for data centers)
- Virtualization and orchestration are de facto standard tools (OpenStack) for cloud services
- Aggregation of core resources (clouds)
- More and more distributed users and number of devices (IoT)
- Software for everything paradigm

Data / Control plane platforms
Data plane : OSHI – Open Source Hybrid IP / OpenFlow networking
• IP and SDN hybrid networking over Linux
Control plane : ICONA – Inter Cluster ONOS Application
• Extending ONOS controller to a geographically distributed scope
The experimental platform : Topology 3D (Designer Deployer and
Director)
• Easy design, deployment and control of the experiments

Lessons learned and Comments
(+) SDN is not just OpenFlow SDN is a paradigm wider than a
single technology (-) Speed of Light is still a constant A physically distributed set of resources cannot be centrally
managed in real time unless the distance is ~ zero) (-) Debugging (i.e. operations) is much more complex. The
software layer is much thicker than now
(+) Networks function can be "easily" added (-)(+) New expertise is needed

Last comments
(-) Operation, CyberSecurity, SLAs, new expertise may actually
mean that the devil is in the details [Operational EXpenses >> CAPital Expenses]
For Research and Education, an open, secure, inter domain
transparent and neutral communication (for services, resources, information sharing,...) is key instead (and probably
for smart cities, societies too).
