• 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 …

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
• … Strong Role for Innovative Standards

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
considering a broader standards proposal in a Active (and actively partecipated) WGs

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 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
means for the network

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
