2 Why? Network Softwarization : a brief recap Reduce costs (increase efficiency) Increase flexibility and ease evolution Allow dynamic deployment of functionality Simplify network management Open up new revenue opportunities on-demand, agile, elastic network services 17/09/2013 Nicola Blefari Melazzi, blefari@uniroma2.it, 2

3 Softwarization: a brief recap Software Defined Networking (SDN) an architecture with a logically centralized control plane and a welldefined separation between user and control planes Network Functions Virtualisation(NFV) deployment of network functions as software components running on industry-standard commodity hardware platforms Cloud networking outsourcing to the cloud not only processing and storage and applications but also networking services images from keynote speech of Nick McKeown at the 23rd International Teletraffic Congress Prodip Sen, Verizon Communications, Webinar 17/09/2013 Nicola Blefari Melazzi, blefari@uniroma2.it, 3
