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 2.5-3G
  (http//www.gsmworld.com/)
• Wi-Fi usage growing rapidly

5
Trends in Computing

• Moores 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

6
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

Wireless Technologies

• PAN - Bluetooth IrDA
• Cable replacement
• WAN
• Paradigm shift to wide band packet data
• Europe and US GPRS
• Japan WCDMA
• Media aware applications are key
• High latency networks
• LAN - Wi-Fi (802.11)
• Price point for APs and cards dropping
• Rapid adoption in Enterprise and Home Networks
• MSFT deployed over 31000 clients over 3000 APs

15
Wireless Requirements

• Zero configuration
• Consistent model across phones, PDA, PCs
• Always connected
• Unified transport IP

• What about Bluetooth?

18
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

19
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)

20
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

21
Bluetooth Support Roadmap

• Bluetooth release plans for Windows XP
• Next beta in Q2
• Shipping in 2H 2002
• Support for Windows XP and beyond

22
Key Ubiquitous Connectivity Challenges?

• Addressing
• Mobility and roaming
• Security

23
The Promise of IPv6

• Enough addresses
• 6464 format 1.8E19 networks, units
• assuming IPv4 efficiency 1E16 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

24
The Promise of IPv6If IPv6 is so great, how come
it is not there yet?

• 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

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-gtv6 transition strategies

26
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
