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 -3 G (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 100 Gb per square inch hard disk density 128 MB 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, e. Books
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
The Opportunity
The Wireless Market
Wireless Applications Drivers Source: The Yankee Group, November 2001
In Millions Wireless PAN Market Source: Cahners In-Stat Group
Wireless LAN Market Source: Cahners In-Stat
Wireless WAN Market
Wireless Networking
Wireless Technologies PAN - Bluetooth & Ir. DA 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
Wireless Requirements Zero configuration Consistent model across phones, PDA, PCs Always connected Unified transport: IP Mobility & seamless roaming Unified security model through standards Adhoc Qo. S Affordable pricing and cost monitoring Smarter applications and services
Wireless support in Windows XP WLAN Wi-Fi zero configuration Secure LAN access Transparent roaming WWAN Always-On driver model Improved TCP performance
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 (IPv 6 only) ESDP (UPn. P over IP)
Bluetooth Application API Set Windows XP Application API set Winsock IPv 6 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 Q 2 Shipping in 2 H 2002 Support for Windows XP and beyond
Key Ubiquitous Connectivity Challenges? Addressing Mobility and roaming Security
The Promise of IPv 6 Enough addresses 64+64 format: 1. 8 E+19 networks, units assuming IPv 4 efficiency: 1 E+16 networks, 1 million networks per human 20 networks per m 2 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 IPv 6 If IPv 6 is so great, how come it is not there yet? Applications networks Need upfront investment, stacks, etc. Similar to Y 2 K, 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 IPv 6? Building a complete IPv 6 stack in Windows Technology Preview stack in Win 2000 Developer stack in Windows XP Deployable stack in. NET Server & update for Windows XP Windows CE planned Supporting IPv 6 with key applications and protocols File sharing, Web (IIS, IE), Games (DPlay), Peer to Peer platform, UPn. P, Bluetooth Building v 4 ->v 6 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 IPv 6 is a key requirement
