What’s behind SDN ?
• Separation of the data plane and the control plane of the networkarchitecture
SDN and NFV, disruptive technologies in network (1/2)

Centralization of the network control plane as a software program
SDN and NFV, disruptive technologies in network (2/2)
What’s behind NFV?
• Implementation of network functions or services under a software form
Source: ETSI
Replacing hardware appliances using proprietary interfaces by industry
standard server hardware
Why implementing SDN and NFV for telcos?
Increasingly high pressure on telcos driven by the growing TRAFFIC and EXPENSES

Over 30 Proof Of Concepts First solutions commercially available
“75% of its network to
be virtualised by 2020”
“30% of its new platforms in
a virtualised form by 2016”
Telcos’ announcements
Still, the industry is facing to challenges
Projects are rapidly increasing, but…. Interoperability
Management & Orchestration
Agenda
