Transforming networks with NFV
What does it take to go from NFV trial to a wider commercial operation?
There are multiple strategies and approaches – so the answer really depends
on operators. We have gathered learnings from working with early adopters
to help you define your NFV strategy and make virtualization a reality.

Challenges
Early adopters encountered much broader challenges than
simply overcoming technical obstacles – and demanded new
organizational strategies and technical capabilities, such as
software-defining everything, optimizing VNF performance
for cloud, and OSS integration.
Business case
The most recent market tracker
predicts the global NFV market
will grow to USD 16 billion by 2021.
So, a solid business case is one of
our first recommendations.
Management
MANO capabilities must be provided
across network functions and services.
Network and service layers will require
automation and coordination
to function properly.
Infrastructure
An open, standards-based pre-integrated
NFV infrastructure can save you years of
integration time, reduce complexity,
lower risk, shorten time to market and
increase operational efficiency, all while
laying the foundation for 5G.
Reliability
To ensure reliability, NFV infrastructure needs
telco-grade capabilities – but managing
these can be very challenging. We recommend
software-defining everything when it’s time
for modernization.
Cloud native
Thinking of overhauling your code to make
better use of cloud resources? You might be
better off starting from scratch when writing
cloud-native NFV applications for telco
environments and digital services.
Performance
It might seem like VNF performance can't match that of physical networks
– but the other benefits of telco-grade VNFs make it well worthwhile.
However, there are requirements. To secure multi-vendor network functions,
you must differentiate between IT and telco workloads. Creating integrated,
functional service packages and employing an agile DevOps model will
secure throughput capacity and latency.
Migration
A comprehensive, cross-functional migration
plan – one that defines an overarching
blueprint, identifies dependencies, aligns
efforts, budgets true cost and measures KPIs
– will help you make a start and avoid
getting stuck in future.
Good luck!
