Trends in Networking
Data traffic exceeds Voice traffic
Carriers shifting to network designs that favor packets

High broadband adoption in geographies where available
Carriers responding to demand

Wireless deployments everywhere
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

What about Bluetooth?

Microsoft Focus
Simplified User Experience Enable the wireless desktop
Mouse, keyboard, printer, modem

Enable rich scenarios over Bluetooth
Migrate to Internet standards

Consistent model and experiences across different devices Enable seamless roaming
Seamless Wi-Fi/Bluetooth roaming

Bluetooth support for Windows XP
Simplified User Experience
Service discovery protocol Binding/pairing UI

Wireless Desktop
Printing using HCRP Access using DUN Keyboard and Mouse using HID

Adhoc Connectivity
PAN (IPv6 only) ESDP (UPnP over IP)

Bluetooth Application API Set
Windows XP Application API set Winsock IPv6 namespace and ESDP Defined in the system SDK Enables application portability Enables applications to extend beyond Bluetooth Propagates wireless advancements made in Windows XP

Bluetooth Support Roadmap
Bluetooth release plans for Windows XP :
Next beta in Q2 Shipping in 2H 2002

Support for Windows XP and beyond

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?
networks
Applications
Need upfront investment, stacks, etc. Similar to Y2K, 32 bit vs. “clean address type”

Network
Need to ramp-up investment No “push-button” transition

applications

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
