Todays network infrastructure NFV in nutshell Terms and
definitions of NFV NFV High Level Architecture Benefits of NFV
Existing NFV solutions Which is better SDN or NFV ? My work
Slide 3
Diverse network functions (NF). Providing desired overall
functionality or service. Adding new services New service instances
take weeks to activate New service types may take months up to
years New service types require either new equipment or upgrading
of existing equipment
Slide 4
Cisco thinks about 50 billion devices will be connected by
2020, after coming out with an earlier analysis in January that
claimed 8.7 billion connected devices in 2012. We have to
simplifying network design, increase agility, speed up deployment
of new services.

Reduce Capex reducing purpose-built hardware, supporting
pay-as-grow Reduce Opex reducing space, power, cooling of equipment
Accelerate Time-to-Market reducing the time to deploy new
networking services Deliver Agility and Flexibility scale up or

CloudNFV taking NFV to the Cloud Implementing NFV based on
cloud computing and SDN in multi-vendor environment. The network
and applications are not just equal, but the same in the cloud.
Product of cooperation between 6WIND, CIMI, DELL, EnterpriseWeb,
Overture Networks and Qomos Contrail developed by Juniper
networking solution that automates and orchestrates the creation of
highly scalable virtual networks. Cisco ONE offers the broadest
approach to open, programmable networks, including SDN controllers,
open APIs, and virtual network infrastructures across a variety of
deployment models.
