Overview of NFV and connecting with SDN

Report
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
