Technology Shapers
• Internet uses any communication service (IP on everything!)
• IP carries anything digital
• End/End Principle (neutrality and user freedom)
• Radio supplies mobility
• Fiber/Cable/DSL supplies speed
• Broadband (choice, symmetry)
• IPv6 supplies address space • (IPv4 runout in 2011)

Socio-Economic Effects of Internet
•Information Consumers are becoming Producers – Blogging, YouTube/Google Video, Personal Web Pages
•Innovation at the edge (e.g. wikipedia)
•Social Networking (Linked in, My Space, Facebook, Orkut…)
•Gameplaying (Second Life, World of Warcraft…)
•New Business Models– eBay, Amazon, Dell, Google, Yahoo!,MSN, AOL, iTunes, VOIP…
•Internet can transport and display print, video, audio media
•Internet permits group interaction (not only mass one-way medium)
10
IPTV
• Streaming and Downloading – iPOD and vPOD behaviors?
• Mixing of all media as IP packets
• Ancillary information access
– Downloaded texts, programs, videos, audio, captions
– Advertising material
• Screen Control (icons, widgets)
• Multiple streams to multiple displays (beauty of packet switching)
• Online interaction while viewing
– Group commentary
– Advertising and product information
11
Mobility and Mobiles
• 2.5 Billion Mobiles and counting
• Innovative interface challenge
• Text/Web Access
• Payment systems
• Access to Web searching
• Navigation systems– GPS, Galileo, Google Earth/Maps,…
• Geo-location based services
12
Internet-enabled Devices
13
Internet-enabled Devices
Programmable – Java, Python, etc.
Examples:
• WebTV, Personal Digital Assistants, Mobiles,Video games, Picture Frames, Washing Machines, Surf Board!
• Refrigerator (and the bathroom scales)
• Automobiles (Japan, Germany)
• Internet-enabled wine corks (also note new quantum theory of wine: Schrödinger’s wine bottle)
• Internet-enabled socks (clothing)
• Universal Remote Controls
14
Recent and Coming events
• Introduction of Internationalized Top Level Domains
– See idn.icann.org for current testing
• Introduction of new generic and cc TLDs in 2008
• Introduction of IPv6 (root zone, elsewhere)
• Introduction of DNSSEC (.se, .bg, .br, .pr, …)
• Internet Annual Meeting (Los Angeles, Oct 29-Nov 2, 2007)
• Internet Governance Forum (Rio de Janeiro, Nov 12-15, 2007)

Interplanetary Internet:“InterPlaNet” (IPN)
•Planetary internets
•Interplanetary Gateways
•Interplanetary Long-Haul Protocol
•Delayed Binding of Identifiers
•Email-like behavior
•TDRSS and NASA in-space routing
•Delay and Disruption Tolerant Protocols– Tactical Mobile applications (DARPA)
– Civilian Mobile applications (SameNet!)
