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 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 Need upfront investment, stacks, etc. Similar to Y2K, 32 bit vs. “clean address type” Network Need to ramp-up investment No “push-button” transition networks 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
