Rush to serve data over Cellular networks: 2.53G (http://www.gsmworld.com/)
Wi-Fi usage growing rapidly
Trends in Computing
Moore’s Law still going strong
Smaller, more computing devices every 18 months
Miniaturization continues
100Gb per square inch hard disk density
128MB memory on a single chip
Dramatic innovation towards longer battery time
Low power CPUs from Intel, Transmeta, AMD
Fuel cell battery (1 month cell phone use) on the horizon
Smaller, lighter PC, PDA, phone designs enabling
new networking scenarios
TVs on Cell phones, Wearable computers, digital cash,
eBooks
Trends in Applications
XML revolution leading to web services
Peer-to-Peer enables compelling scenarios
“Presence” a paradigm shift in Real Time
Communications and Collaboration
Net attached Consumer Electronics and
Gaming appliances emerging
Applications assuming always on
connectivity, anywhere

Key Ubiquitous Connectivity
Challenges?
Addressing
Mobility and roaming
Security
The Promise of IPv6
Enough addresses
64+64 format: 1.8E+19 networks, units
assuming IPv4 efficiency: 1E+16 networks, 1
million networks per human
20 networks per m2 of Earth (2 per sqft )
Removes need to stretch addresses with NATs
True mobility
No reliance on Foreign Agents
Better network layer security
IPSec delivers end-to-end security
Link/Site Local addresses allow partitioning
Anonymous addresses provide privacy
The Promise of IPv6
If IPv6 is so great, how come it
is not there yet?
Applications
networks
Need upfront
investment,
stacks, etc.
Similar to Y2K, 32
bit vs. “clean
address type”
Network
applications
Need to ramp-up
investment
No “push-button”
transition
What is Microsoft doing to
Accelerate Migration to IPv6?
Building a complete IPv6 stack in Windows
Technology Preview stack in Win2000
Developer stack in Windows XP
Deployable stack in .NET Server & update for
Windows XP
Windows CE planned
Supporting IPv6 with key applications and
protocols
File sharing, Web (IIS, IE), Games (DPlay), Peer to
Peer platform, UPnP, Bluetooth
Building v4->v6 transition strategies
Conclusion
Wireless WAN, LAN, and PAN are
complimentary technologies for exciting
connected scenarios of the future
Pervasive networking requires rich
integration of technologies
IPv6 is a key requirement
