Goal s

Deploying virtualized platforms and utilizing NFV in Telco environmentHow can NFV help integrated service providers better utilize and control

infrastructure?Can network platforms and Telco IT systems share the same infrastructure cloud?What are the best candidates from service/network platforms for NFV in a Telco

environment?What we need to change in our BSS/OSS systems to support NFV?What is ST experiences with platform virtualization?How can NFV and SDN change the Telco industry and what is the right role of

standardization?

Concl usionsSDN and NFV are industry trends that can helps to integrated service providers betterutiliseand control their

infrastructure (in network and DCs) with the higher level of orchestration and automation. NFV has to bring additionalbenefits compare to server/network virtualization.Infrastructure cloud have to enable the independence from underlay physical hardware (compute, storage, network)

that HW should be generic and cheaper as proprietary solutions. It SHALL enable virtualization of resources,flexibility and elasticity.There exist multiple candidates for NFV in Telco environment cross all domains but looks like evolution approach

and hybrid scenarios need to be applicable case by case. Triggering points will be maturity, performance and costeffectiveness for particular function.

SDN and NFV are not competing technology and can be deployed independently or combined together.Definitely NFV and SDN have chance to change the Telco industry but open question remains when and how to

optimally utilize it.Adopting BSS/OSS for SDN/NFV will be crucial for leveraging all potential benefits.Standardization play important role but real breaking point will be availability of carrier grade implementations and

interoperability. Open source project and initiatives can helps here.
