We are evolving towards a Hyper Connected and Intelligent Digital World*

The explosion of digital services makes connectivity

services more needed than ever

Reduction of Time to Market

Radical increase of traffic in telco networks

New ways of communication and increasing number of “always-on” users

Smartphone is changing everything

We need to adapt and define the change to lead in the Digital era

• Very intensive in hardware

• Capital intensive

• Software is not a core

Telco players Internet players

• Very intensive in software

• Can have global impact with not too much capital

• Hardware is a support, and is located in the network periphery

Today DIGITAL means SOFTWARE!

Our vision is to have a software-based network that delivers the best connectivity

experience in an efficient and flexible way

Goal

To cope with quick changes and uncertainty

Mouldable infrastructures

To understand changes inside-out

and be able to decide in real time

Insight capabilities

DIGITAL TELCO

To adapt our offer to users necessities

User Centric Connectivity Experience

How

• Making infrastructure uniform

• Facilitating interoperability

• Improving risk management in a changing environment

• Fostering competition & innovation

• Minimizing entry barriers

• Making capacity addition flexible and easy

• Simplifying network operation

NFV promises to transform the Telco industry, being operation one of the key levers

Architectural principles for the virtualization of everything

Common homogeneous and versatile infrastructure based on x86

Orchestration = automatized management

1. Based on the right abstraction layers

2. Based on standards & non-proprietary solutions

3. Based on modular blocks that allow different paces

of evolution

DESIGN PRINCIPLES

• Enhanced user-centric connectivity experience

• Homogeneous and versatile infrastructure and simplified and automated operations

• Mouldable software-defined functionality

• Agile and open innovation

… since data plane virtualization has a potential higher economic impact than just

control plane virtualization

E2E ORCHESTRATION

AS SIMPLE AS POSSIBLE

We need a reference architecture to ensure carrier class, operability and a healthy

ecosystem

AVOID VERTICAL INTEGRATION WHILE ASSURING PERFORMANCE

FOSTER A NEW ECOSYSTEM

Software appliances

(network functions) must be

portable

• Lowering entry barriers for new players

• Engaging established vendors

Network Virtualisation is not Cloud Computing

The network differs from the computing environment in 2 key factors:

Data plane workloads

(which are huge!)

Network requires shape

(+ E2E interconnection)

NEED OF HIGH AND PREDICTABLE PERFORMANCE (as with current

equipment)

GLOBAL NETWORK VIEW IS REQUIRED FOR MANAGEMENT

…which are big challenges for vanilla cloud computing

…and most of industry is offering to Telcos just IT based cloud products as network virtualization environments

NFV technology is almost there, but focus is needed to ensure readiness

CARRIER-GRADE PERFORMANCE CLOSE GAPS IN UNDERLYING TECHNOLOGIES

(HW, OS/hypervisor & VIM)

Main challenges Our strategy to make NFV happen:

AVOID VENDOR LOCK-IN CONTRIBUTE TO KEY OPEN SOURCE PROJECTS

(KVM and OpenStack)

AVOID COSTLY INTEGRATION PRE-PRODUCTION REFERENCE IMPLEMENTATION (NFV Reference Lab) INVOLVING ALL INDUSTRY,

to minimize integration efforts

efforts and avoiding vendor lock-in

This new network model will help us to deeply transform our factory…

Global E2E vision instead traditional silo model,

not linked to monolithic OSS Breaking the traditional model mapping isolated network domains

• Computing principles used in IT world are beginning to be applied in telecoms by the means of Network Virtualization

• IP as common language for all services, included traditional Telco ones

• Network virtualisation enabling network re-programmability & agile service creation

Operation Model Change
