Digital Natives … a new Literacy

Our Teen Children

• 80-160 sms & What’s app msg /day

• Up to 2000 – 5000 messages / month

• No TV … on TV, but … youtube, facebook,

skype video call …

• Uploading lot of images on Facebook

• Doing research and studying (really!!!) with classmates by means of internet

• Facebook, skype, chatting, smartphone apps, wikipedia, google, e-mail all open at

the same time

• In case of a problem can refer to friends … wikipedia, facebook, sms, skype calls …

• 1 laptop and web cam, digital photo, and 1 smartphone ‘wi-fied’ at home, 1 ADSL; at

least … 2 IP addresses (… what are they? …)

4

• Skype video call as a main way to study with

far away classmates http://marcprensky.com/writing/Prensky-TheRightStuff-EdTech-May-Jun2012.pdf




eDemocrazy – technology and elections

5 STAR MOVEMENT (ITALIAN ELECTION)

OBAMA TECH TEAM

• 4Gb/s, 10k requests per second, 2,000 nodes, 3

datacenters, 180TB and 8.5 billion requests.

Design, deploy, dismantle in 583 days to elect the

President. #madops

5 STAR MOVEMENT (ITALIAN ELECTION)

• Beppegrillo.it within the 50 most accessed web site in Italy

• No TV appearence, but a dedicated TV channel on internet

• Online video during the ‘Tsunami Tour’ politics meetings

• At the final meeting 150.000 people online

• Online subscription and funding, public funding refused

• Supporters coordinating by means of internet

• Resulted in being the first Italian party in the Chamber of

Deputies and the second in the Senate

Main AspectsMain AspectsMain AspectsMain Aspects

• Huge Growth of connected devices and communication needs

• Different Uses, Users (Human and Not Human ) and Traffic

Loads

• Network expected to be available and capable every time

• Growing complexity (number of nodes, interfaces, protocols,

configurations, connections, hw, sw …)

• Different Vendors and capabilities

SDN Standard activities

– Main Forum on Software Defined Networking

– Current focus on OpenFlow interfaces

– Partecipation of Cisco, HP, Juniper, IBM, Ericsson, Alcatel-Lucent, VMware, NEC,

Orange, Comcast, KDDI, Level3, Telecom Italia, etc

10

► Started a research group on Software Driven Networking in order to

allow interaction between application and network routing

► Still in start up mode; could fill the missing aspects of ONF (the control

layer over OF and the data layer )




ETSI ISG NFV Standard Activities► ETSI ISG NFV is the current industry reference group on Network Functions

Virtualization

► TI among the founding members; partecipated by the main Network Operators

(TI, TEF, ATT, Verizon, DT, KoreaTel, NTT, Vodafone, Telefonica) and almost all the

vendors (Cisco, Juniper, Ericsson, Huawei) and start ups (Connectem, Affirmed

Networks)

Pre-standardisation study (max 2 years) before

Pre-standardisation study (max 2 years) before

considering a broader standards proposal in a

new or existing standardization group. Goals:

► Reduced equipment costs and power

consumption

► Reduced operational cost by exploiting cloud

technologies and IT orchestration systems.

► Accelerated time to market.

► Re-usable hardware infrastructure

investment

• First face to face meeting on January 13

Active (and actively partecipated) WGs

1. INF – Virtualisation Infrastructure

2. SWA – Software Architecture

3. MANO - Management and Orchestration

4. REL - Reliability & Availability

Yet to be started

► Performance and Security Expert Groups




The ITU Future Network Vision

Logically Isolated Network Partition




Phisical Networks will be partitioned, virtualized and assigned to different users

LINP –– ––Logically Isolated Network Partition




► SG13 Future networks including cloud computing, mobile and next-generation networks

► Work at the Architectural level

► Envision Network virtualization as enabler to run multiple service networks (LINP –

Logically Isolated Network Partitions) over a phisical network infrastructure




The network ain't what it used to be

• Based on a common infrastructure, ‘Virtual’ Networks will

be mounted and dismounted for different uses and users

in a flexible way

• We expect Virtual Networks growth and reduction based• We expect Virtual Networks growth and reduction based

on different needs and loads

TI Standard Activities

ISG NFV

►Actively partecipating to the ISG NFV: editor of use case

document of the Network Operator Council

►Interest in Mobile Core Virtualization

SDN

►Monitoring the evolution of SDN activity in ONF and the other

involved Standard Bodies (IETF, ITU)

►Improve understanding of what a software defined evolution

Remark #2: Management

• Need for standardization of common management

interfaces with open standards within a service oriented

architecture (SOA)

• Reduce the effort to interoperate with current OSS / BSS

systems (note: there will be always legacy systems ahead)systems (note: there will be always legacy systems ahead)

– Network Discovery, Inventory, Fault and Configuration Management

– Customer DB on CRM

• Easy Programmability of new networks, common

language to configure and manage new networks

• Deployment testing and verification, management

interface verification

Summary

• IP-based Networks are already radically changing the

world, and will continue

• Need a strong and innovative role of the Standards

• Deployment and Management are major concerns• Deployment and Management are major concerns

• Manage synergies among SDOs towards a common

objective avoiding overlapping
