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

Services Ubiquity and
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
Hybrid Networks, radio resources optimization

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

Perspectives: Polymorphic Networking Environment
• Composability• Autonomicity• Virtualization,• Programmability
Towards a mesh of new networking paradigms
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:
