The present situation Evolution of infrastructure based networks Disruption at the edge Perspectives

The present situation

Examples of present services: Triple play, Quad play • Internet access, Telephony, IPTV, Mobile convergence,…• Fix and mobile broadband connectivity increasing fast

- 1 Billion Broadband mobile users expected by 2011 Service overlays• Skype,…

Multimedia digital content and end user empowerment • YouTube, Daily Motion, Facebook, MySpace…

Coexistence of two models • NGI, NGN - The question of neutrality

The Internet plays today a major socio-economic role• It was not designed as a critical infrastructure for the economy, the

society, etc. Major investments on the Internet of the Future• Evolutionary and disruptive approaches

Disruption at the edge

Services ubiquity and global mobility

Ubiquity of Personalized and Adaptable Services• Ubiquity of personalized services

- based on a large diversity of access technologies

• Services adaptability: Location and Context Awareness • Services composition, advanced services’ orchestration

Global Mobility• Services and Sessions Mobility across terminals, technologies and

administrative domains• Always Best Connected• Any terminal is your terminal (bio identification, ...)

- SaaS

• Networks Mobility

Multi-Network Services

Multiple services agnostic to the diversity of access technologies

Global Mobility

Examples of related technology evolution

Transparency: Higher capacity, Qos control (e.g. latency), Advanced Mobility Management • E.g. LTE-Advanced (LTE-A)

Optimization: Cognitive radio, Base Stations cooperation, Terminals cooperation, Relaying, …

Backhaul Networks

Backhaul Networks• PSN based metro networks• Transparent access/metro networks (NG PONs)

- New carriers‘ architectures: Reducing the number of central offices

• Sharing backhaul infrastructure- E.g. Radio over Fibre

Critical for SPs, Business opportunity• Level 3 launched a wireless tower access service offering wireless

tower operators direct connectivity to the Level 3 backbone• Tower Cloud Inc., a wireless backhaul provider raised $20 million last

week• Qwest launched a new mobile ethernet backhaul service, targeting

wireless service providers with fiber-based Ethernet to cell sites

Core Networks

Core Networks• IP and optical networks convergence

- Optical burst switching coming back to the arena

• Inter-domain services- New business models between operators, service providers...

• Beyond IP and new routing paradigms- Identification and location separation- Semantic routing

• Overlay functionality moving into the network- Virtualization

Spontaneous and opportunistic networking

A ring of spontaneous and opportunistic networking • From terminals to networking capable devices

- Operator-less networks (e.g. ad-hoc, MANETs)

• Self-organized mesh networks- Last mile under the control of the end users or new players?

• Opportunistic networking in operator networks- E.g. Mobile terminals behaving as relays for a global spectrum optimization

• Vehicular networks• Random Connectivity may behave as permanent connectivity

depending on the density of communicating devices- Keyword: self-organization

Delay Tolerant Networks

PSN: Pocket Switched Networks DTN today: a nice research concept DTN tomorrow: the density of devices with networking capabilities

will increase Example of application: Dissemination of information obtained from

info-stations through NFC

Source: HAGGLE, FP6 European Project

Networking will reach every electronic device

Merging the real/physical and digital worlds• Wireless Sensor Networks (WSNs) and Actuators• Augmented reality, Virtual reality environments (3D Internet)• Network transparency

Machine to machine and ambient intelligence• Beyond RFIDs

- Today, application example: the EPC global network, RFIDs and beyond- Tomorrow: new generation active RFIDs

• Towards the Internet of things and the real world Internet• Providing integrated experience

Key challenges

An immense range of applications in health, environment, transport, energy, security, home, etc.• Facilitate a faster adoption of these new technologies for the benefit of

the future networked society• Understand and lead the various potential vertical markets

Deal with new complex governance issues• In particular with related privacy issues

Requirement for innovative networking architectures, security paradigms, naming approaches, information search and maintenance, etc.

Services evolution

Ubiquity of personalized services, Location and Context Awareness, Services composition, services networking

From web of documents towards the web of services (web 2.0), knowledge, things, semantic web (web 3.0), sites personalization (intelligent marketplace), etc.

The central role of end users• Secondlife, Face Book, etc.

Merging with the real world• Augmented reality, virtual worlds and the 3G Internet, real time games,

telepresence Business Aware carrier services enabling new business processes

Residential and Business services evolution

Home networking: beyond “just” networking• Convergence of Communication, Information, Entertainment, Home

automation and persons and goods security• Robust and self-organized networks

- Free Space Optics- Self-configuration, self-healing

Business services: beyond “just” networking• Support of new enterprises business processes

- Added value VPN services (e.g. Business Aware VPNs)

• Support of advance Machine to Machine solutions• Data centers evolution (outsourcing), Software as a Service

Summary

An holistic approach of the Future Internet requires dealing simultaneously with• Future core networks• Future convergent access networks• A first ring of self-organized opportunistic networks• A second ring of communicating devices allowing for merging the

physical and digital worlds• A new generation of services infrastructures, services production and

consumption approaches• New paradigms for content production and distribution• And More:
