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 Networking
14
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
  • Mobility seamless roaming
  • Unified security model through standards
  • Adhoc
  • QoS
  • Affordable pricing and cost monitoring
  • Smarter applications and services

16
Wireless support in Windows XP
  • WLAN
  • Wi-Fi zero configuration
  • Secure LAN access
  • Transparent roaming
  • WWAN
  • Always-On driver model
  • Improved TCP performance

17
  • 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 IPv6 If 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

25
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
