Agenda
•
A New Context for Telecomms
•
•
The Rising Importance of Data
•
•
•
Many paradoxes …
IoT and Data
Personal Data = Data + Identity
Deriving some requirements for Operators’ Platforms

A New Context for Telecomms
R. Minerva, Telecom Italia / Future Centre
Towards 2020: the future of
networks
•
•
•
Fiber reaches a large part of homes and enterprises, it
guarantees:
•
Services strongly related to users and their social relationships
•
Identity Management and their association to Biometric techniques
–
Unlimited bandwidth
•
Different roles and identities per user
–
Low cost per bit
•
Diminishing role of SIMs
–
Everywhere connectivity
–
flat rate also for mobile
•
Fundamental Role of Terminals
•
Abundance of Storage (1TB in the terminal, toward infinite in the
network?)
User is ABC (Always Best Connected)
–
Transparent Connectivity (user always connected at the lower prices
and best bandwidth)
•
High processing Capabilities in the terminals (context controlled locally
by the terminal)
–
Strong Integration (at the terminal level) between mobile and fixed
networks
•
Capability to interoperate will be embedded in terminals and will be
downloadable OTA
–
Cognitive Radio (terminals adapt to the available networks)
•
–
Rapid change of Providers
–
Dynamic Business Models
Software embedded in the terminal makes the device more a personal
service platform than a product. They will be personalized according to the
specific user needs
–
Users connected to smaller, more efficient and cheaper cell
Importance of Data
–
Seamless access to personal data
–
Capability to dynamically create, aggregate and update personal
data
–
New data type and data sets
–
Integration between real and virtual related data
–
User controlled access to data
R. Minerva, Telecom Italia / Future Centre
•
Pervasive Communication
•
Ubiquitous connectivity
•
Broad classes of communicating objects (smart object, beacons, smart
materials, sensors, micromachinery, ...)
•
Explosion of Augmented Reality and Internet of Things applications
Connectivity is a commodity
Terminals are flexible and personal service platforms
Data center larger and larger

Two approaches
Lean Operator
• Networks will become highly
dynamic Complex Systems made
out of many heterogeneous
networks, systems and
intelligent endpoints
• Complexity will result in:
•
•
•
Costly infrastructure difficult to install, manage and
integrate
Lack of optimization of usage of resources
Lack of knowledge of the “network" as a whole and
how it is globally and locally behaving in supporting
customers requests
0-Touch Networks
R. Minerva, Telecom Italia / Future Centre
Smart Operator
• Decoupling Services
from the Network
•
•
Global reach independent of the
access network;
mashup of local and global resources
(Net of Nets)
• Provide Global Services
•
•
the long tail is much bigger
because the marginal costs of a global
solution are smaller (Skype: the costs
for building a global software are
marginal)
De-perimeterization of
Services 

Objects, Terminals, Networks as
Personal Info Producers
Intelligent Terminals

UWB,
BT,
…
R. Minerva, Telecom Italia / Future Centre
3G, 4G,

public
nets,
…
How Many Nodes, How Many
Messages, How Much Bandwidth ?
Issue: low average traffic, but highly
impulsive traffic
(e.g., SPIKES: all objects wake up at 3
a.m. and send high priority messages)
Likely the communications
between nodes will be
framed into B2B2C
relationships
Many objects/nodes will
come with communications
already paid for (I.e.,
embedded
communications)
10 M Aggregators
Message size: 10 kB

Millions GB/Year
Operators should try to be
Aggregators by providing
real-time messaging
engines (e.g., based on
PubSub), by creating
communities, and by
supporting the deployment
of the infrastructure (at
home and in the public
domain)

Some Issues with networked data
R. Minerva, Telecom Italia / Future Centre
A “user-centric personal data eco-system” (WEForum)
Volunteered data: created and explicitly shared by individuals
Observed data: captured by recording the actions of individuals
Inferred data: based on analysis of volunteered or observed information;
R. Minerva, Telecom Italia / Future Centre
Personal Data
should be properly
managed
Excerpt form: “Personal Data - The Emergence of a New Asset Class” (WEF)
Source: Bain & Company
A First Issue: proper Management of Personal Data
•
But what is the Value of Personal
Data?
The value of the single datum depends on the usage context:
•
•
•
Time reference: V(CreditCard, today)>> V(CreditCard, 4years ago)
The value of the Person in the usage context:
•
•
The kind of collected datum: V(CreditCard) >
V(SocialSecurityNumber)
Importance of the person V(CreditCard, SB) >> V(CreditCard, RM)
The linkage of the datum
•
The connection of the datum and the person:
•
•
•
How many data can be connected to the datum (es.: FoaF)
Is the datum owner well connected (a Hub kind of person)
V(a) > V(b)
How much data
(derived from http://www.thoughtfarmer.com/blog/2009/04/27/intranet-roi/)
•
Metcalfe’s Law: n(n-1)/2
•
Reed’s Law: 2n – n-1
•
Briscoe, Odlyzko, and Tilly Law: n log (n)
•
Beckstrom Law: V = ΣB – ΣC
Identity of Things
• Things can collect user related actions and data
• Each Thing can be used for tracking Users
• Owners of Things can collect a lot of data
•
Each Resource is
addressable
•
Each resource is
CONNECTED
– Connectivity must
be guaranteed in a
variety of
environments
– Secure Links have
to be guaranteed
•
Each Resource can be
associated to a User
(Identity)
• Who owns these
relations :UserId Location ResourceId - data
used/generated ?
Dealing with Data: Data Anonimization,
Contracts and Contextualization

unpredictable ways

A Second Issue: Complexity is moving
to the edge
•
Functionalities and data generation/consumption and storage in the edge
•
•
•
Networks will comprise smart objects and processing, storage, communication
resources
Data and Info will be the user target and not mere connectivity
Complexity coalesces at the edges (more nodes and more capabilities)
•
While big networks are flattening and becoming simpler (less nodes)
•
Local aggregation vs. average coverage
•
Aggregation of intelligent points will be mainly unpredictable and even if high average
connectivity capabilities will be provided, such a dynamic concentration will challenge
the networks capabilities
•
•
•
Competition for scarce resources for a limited period of time
Terminals will have a key role
•
Terminals as an integral part of the communication environment
•
Mobility will be assumed for the majority of terminals
Need to control new complex systems without human intervention
•
The Operator's network needs to support and help in this new context
R. Minerva, Telecom Italia / Future Centre
Dealing with Complexity at the edge:
Self-Organization of Networks
Management of complex and
dynamic “Network s of
Networks” will be critical
• No human intervention
possible
• Competition on resources
Require
• Self-organization
• Game theory techniques
for highly distributed
systems

A Tussle: Future Internet and Identity
•
There is a need for an Identity Layer in the Future Internet
•
•
•
•
For freeing people from Identity Providers
•
•
•
•
People have the right to exist independently from a provider
People are the owners of their identity (and names),
homonymies should be managed in a far way (way just one
Mario Rossi when there are plenty …)
Open framework
•
•
For identify people
For identify things
To relate things, people and places
Many options, and, in certain circumstances, support for
Certification by a provider (a bank), the government, others
Need for a lot of standardization and discussion
Need to safeguard and protect the ownership of data
R. Minerva, Telecom Italia / Future Centre
A Bit of Technology
R. Minerva, Telecom Italia / Future Centre
Current Paradigms are not future
proof
Control Layer
Network Intelligence (e.g.,
IMS) is a hierarchical
model based on the
assumption that control
has to be exerted by a few
specialized control nodes
Resources
Physical Layer
Client – Server model totally
disregards the network aspects
and can easily lead to a
tragedy of commons (misuse
of common networking
resources)
R. Minerva, Telecom Italia / Future Centre
Client

Server
Ossification of Internet and
Perspective for the Future Internet
•
•
•

•
Security. Currently it is tackled as an issue at the edge, while the
network(s) could contribute to relieve some issues (e.g., DDOS)
Mobility, the current Internet has not been designed for an optimal
management of mobility, the Future Internet has to deal with a multitude
of highly mobile objects (mobility built in)
Network Identity, Users are not recognized and managed in the
network, they are managed only at the edges (specific servers or
applications)
Integration of Applications and Transport/Control Layers. Currently
there are not consolidated interfaces that allow for a better cooperation
between the Network and the Apps. Many applications do not use
resources properly (e.g., p2p applications do retrieve data from far away
hosts)
Edges are becoming themselves Networks. There is the need to
understand and manage the dynamics around Networks of Networks: i.e.,
complex systems that impulsively request resources and use them while
these resources have been designed to support statistically determined
needs
27
Focus on data and info and not on transport of bits
Enabling technologies
•
•
•
•
•
•
•
autonomic capabilities and bio-inspired algorithms (e.g., gossiping,
self-organization algorithms), to deal with complexity;
(self-organized) P2P overlays for clustering components, to
guarantee scalability, reliability, and abstraction from underlying network;
resources virtualization, based on abstraction for coping with
heterogeneity and on the definition of dynamic slices for multiple
allocations;
programmable “intelligent” mechanisms, e.g., based on auctions,
game theory, etc., for optimized resource allocation and use;
cognitive cross layering, to allow the network to perceive conditions,
decide and act autonomically to reach local/global/end-to-end goals in an
optimal way, in cooperation with autonomic and self-organizing behavior
of resources;
grid Computing to better integrate different resources (computing
storage and network and to integrate new ones (sensors., actuators,
micromachinery, ...)
Information centric networking to better collect and use the needed
wanted data information
R. Minerva, Telecom Italia / Future Centre
New Control Patterns: Publish –
Subscribe Model
Google code: PubSUb Hubbub
R. Minerva, Telecom Italia / Future Centre
New Control Patterns that
exceed the client-server
and the “network
intelligence” models
• Transaction oriented
processing
• PubSub
Information Centric Networking
http://www.xerox.com/innovation/news-stories/networking/enus.html
http://www.4ward-project.eu/index.php?id=29
4ward project: in this paradigm, the
communication abstraction presented
to applications is based on transfer of
application data objects instead of
the end-to-end reliable byte-stream
used by the majority of applications
today.
Content Centric Networking
A Self-Organizing Network That Meets Information
Needs
What Is It?
A new approach to networking that enables networks to
self-organize and push relevant content where needed.
Content-centric networking enables communication to
happen anywhere, anytime, and with any device - using
any available means.

•
•
•
•
Working on alternative
models for dealing with
personal data
Working on a Network OS
with open APIs
Working on zero-touch
networks (e.g., AFI)
Working on ICN (European

(involving more user associations ?)
Propose an open framework for
Identity and related issues (profiling,
data ownership,…)
Push for a shift from bits to data and
ICN
A Great Initiative for User
