Transcript Overview of NFV and connecting with SDN
Ing. Tomáš Halagan
Today’s
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
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
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.
NFV
– Network Functions Virtualization
Likewise VM
Virtualization – NF and part of the
infrastructure is implemented as a
software.
Result – from dedicated proprietary
appliance to COTS hardware

End-Points
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 down services, inovation
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.
Focusing
on NFV, SDN and their
interconnection
Propose simple plugin to SDN controller,
which could be as orchestrator and
manages VNFs, NFVIs, their deployment
to customers
Use The
Best...
• Linux for Servers
• Mac for Graphics
• Palm for Mobility
• SDN for networks
• NFV for services
• Windows for Solitaire
