Overview of Future Internet
Research
Jan 14, 2011
IEEE Region 10 Technical Seminar
National Taiwan University
Yong-Jin Park
Waseda University, Tokyo
Outline
• Future Internet
– Current Internet Success
– Challenges for Future Internet
– Activities
• USA
• Europe
• Japan
• Korea
• Asia: AsiaFI
– Standardization
The Internet is centric and critical infrastructure
Internet is Top 20 Engineering Innovations in 20th Century
Internet Design Principle
• Basic Goal
– Interconnecting heterogeneous
networks
• Basic Principle
– End-to-End architecture
• Stupid networks and intelligent
terminals
• Resultant Internet Architecture
– Hour-glass model having IP as
common layer
Internet Success Factors
• Well-designed protocols, based on IP –Everything on IP and IP on everything –Built from scratch –TCP/IP code was distributed free of charge
• Technology progress keeps capacity ahead of demand. • End-to-end architecture
– Applications and content creation and dissemination are easy.
• Community –Community collaborates to maintain its health
Future Internet
• The Network of the Future: Internet of 10 years later
– Internet of Things
– Internet of Service
– Internet of Security
– Internet of 3D Media
• Enabling the Future Networked Society (Future Digital Society): a magnitude of pervarsive ICT
Why Future Internet
• Internet Technology
– No big change since 1983
• All ARPANET switched to TCP/IP
• TCP gives End-to-End communication mechanism
• IP gives Hop-by-Hop delivery mechanism
• But environment has changed
– Research networks Commercial networks
– Best effort service QoS service
– Reliable users Crackers
– Fixed hosts Mobile hosts
– FTP, telnet, rlogin Web, Twitter, SNS
Challenges (1/4)
• Scale & Diversity
The globe has been getting networked
• Huge scale: – Internet hosts : 770 M (2010.6)
» originally hundreds of hosts were expected
– Internet users: 2.0 B (2010.6)
» 30% of 6.8B world population
» 450% growth in 2000-2010
– Mobile phone user : 4.6B (2009.12), 3.3 B (2007.12) http://www.internetworldstats.com
100M

Challenge (2/4) • Diversity
– Diverse Networking: BAN, HAN, Sensor Networks, MANET
– Diverse Wireless networks: Bluetooth/Zigbee/WiFi/Mobile
WiMAX/W-CDMA/LTE
– Diverse terminals: Smart Phone, Tablet PC
[Shipment]
• Smart Phone: 293M (2010) 44% 421M (2011) by IDC
(PC: 349M (2010) 10% 385M (2011) by IDC)
• Tablet PC: 19M (2009) 8 times 154M (2012) by Gartner
US continental-scale research platform for discovering and understanding impacts of climate change, land-use change, and invasive species on ecology.

Challenges (3/4)
• Security [Not required in the original Internet]
– Viruses
– DDoS (Distributed Denial of Service) Attack • Yahoo, Amazon, CNN (2001, USA)
– Servers were inaccessible for three hours
• Loss caused by DDoS was more than $ 1B (2005)
– Addressing security comes at a significant cost • Estimated $50-100B spent worldwide on security in 2004
– Spam mails • 95% of the whole emails
• Reliability – e-Commerce increasingly depends on fragile Internet
Challenges (4/4)
• Rapidly growing traffic by Video
– Cisco Forecast, 2009-2014, projects that global Internet traffic will increase more than fourfold by 2014.
– Video is projected to exceed 91% of global consumer IP traffic by 2014.
• Performance
– Scientists have significant bandwidth requirements
• Each science community desires its own wavelength(s) in fibers
– 10-40-100Gbps-(1000Gbps)
AKARI Conceptual Design, NICT 2007.4
Functions have been much more stacked.
Layers have been more & more inserted.
It’s time to build a new Internet from scratch : Clean slate design!

NSF Announces Future Internet Architecture Awards
2010.8, up to $8M each over 3years project
•Named Data Networking (Content-Centric Network)
– Moves communication paradigm from today’s focus on
“where”, i.e., addresses, severs, and hosts, to “what”, i.e.,
the content that users and application care about
•MobilityFirst
– Dealing with mobility as a first class entity allows functionalities like
context and location-aware services to fit naturally into the network
•NEBULA
– Addresses technical challenges in creating a cloud-computing-centric
architecture
•eXpressive Internet Architecture
– Exploring technical challenges in creating a single network that offers
inherent support for communication between current communicating
principles– while accommodating unknown future entities
AsiaFI (Asia Future Internet Forum)
