2 2 Agenda Enabling new engaging experiences Today’s networking challenges IPv6 and transitional technologies Microsoft’s IPv6 status and roadmap

3 3 Deliver New Engaging Experiences Real-Time Communications (RTC) Instant messaging, voice, video Real-time game play / collaboration Collaboration Project workspaces solving a need Sharing your files with other people Shared experiences Concert, company meeting, class Distribution of product updates Pervasive Collaborative Computing!

4 4 Today’s Networking Challenges Development and deployment of these new experiences is difficult End-to-end connectivity is broken Network address translators (NATs) are widely deployed in networks Homes, WiFi hotspots, enterprises, branch offices Networks have a mix of private and public IP addresses Firewalls prevent end-to-end connectivity Users and applications becoming more mobile Developers implement custom solutions Application development is restricted and expensive Use client/server model rather than peer connectivity Complicated workarounds and manual configuration IT and network administrators engineer expensive point solutions Deploy specialized relays and gateways to enable communication between applications and/or computers

5 5 IPv6 Addresses These Challenges Enables end-to-end connectivity More public addresses worldwide Improved allocation for ISPs to provision many public addresses Eliminates need for NATs and private addresses Restores connectivity as appropriate Security for end-to-end trustworthy networking Temporary addresses provide privacy across multiple sessions Authenticated, authorized, tamper proof, private Communication IPSec enables host-based authentication and security at the IP layer to augment edge-based security or obscurity Mobile No need for additional infrastructure or server-side routing

6 6 Misconceptions About IPv6 IPv6 security concepts are vastly different from current practices Reasons for IPv6 have been eliminated by the development of NATs Requires a wholesale network upgrade from the current network infrastructure Businesses Taking a “Wait-and-See” Attitude – Until Now…

7 7 IPv6: Where is the Market Today? “In 2005, all Sony products will be IPv6-enabled.” – Mario Tokoro, Corp Exec VP, Sony Corp, March 2003 Customers Noticeable increased interest in IPv6 in over the past 3 months Department of Defense Announced IPv6 migration starting in Oct 2003, completing in 2008 Independent hardware vendors Hardware vendors have the most-complete solutions Routers with v6 – Hitachi, NEC, Fujitsu, Juniper, Cisco, Foundry Infrastructure Firewalls – CheckPoint, NetScreen Co-existence tunneling technologies available 6to4, ISATAP, Teredo Devices – Nokia Communicator, Ericsson Bluetooth phone Independent software vendors OS support available – Microsoft, Apple, Novell, SCO, Sun, Linux, BSD, etc. Applications – Emerging Network service providers Commercial services in Europe, Asia - NTT Trails in Asia – Japan Telecom, KDDI, JENS, Chita, AboveNet Japan, KPN; Australia – Telstra; U.S. – Verio R&D underway for mobile carriers worldwide

8 8 Moving From v4 to v6 Deployment Method Description Deployment Requirement Relative Cost Today’s Availability Option A Independently deploy IPv6- based consumer and knowledge worker applications IPv6-enabled applications, hosted Teredo service ~0 IPv6-enabled applications are limited Option B Deploy transition technologies into existing v4 infrastructure ISATAP, 6to4$$ HW & SW support available Option CDual-stack Infrastructure upgrade $$$ HW support available Option DNative IPv6IPv6 connectivity$$$$ Connectivity is available in Asia & Europe, limited in U.S.

9 9 IPV6 Transition Technology Overview 6to4 tunneling Provides IPv6 connectivity over the public IPv4 Internet IPv6 traffic tunneled within IPv4 6to4 addresses can be provided by routers, home gateway devices, Windows ICS or by the host itself ISATAP Provides IPv6 connectivity over IPv4 intranets IPv6 tunneled within IPv4 Provides corporations with a central location to provision IPv6 addresses to IPv4 hosts Can serve as a router between native IPv6 hosts and ISATAP tunneled IPv6 users Teredo Provides IPv6 connectivity when clients are behind a IPv4 NAT IPv6 tunneled over UDP/IPv4 Runs only in unmanaged networks today Uses servers to facilitate the creation of global IPv6 addresses for Teredo clients

11 Deploying IPv6 With Windows Multiple techniques are required to cover all deployment scenarios Microsoft is shipping automatic transition technologies today Windows 2003 Server with ISATAP Provides centralized deployment of IPv6 connectivity throughout corporate network Windows XP SP1 Native, ISATAP and 6to4 connectivity 6to4 and Teredo for unmanaged networks Simple installation and configuration to enable basic deployment Microsoft is working with network equipment providers to support these technologies in their hardware

12 Microsoft IPv6 Status Operating system support Windows ® XP SP1 and Windows Server 2003 Windows CE.NET, Pocket PC (2003), Windows Embedded SP1 Windows XP Advanced Networking Pack – IPv6 NAT traversal (Teredo), IPv6 host firewall Developer support Peer-to-peer SDK Winsock, HTTP, RPC, DPlay Visual Studio ® &.Net Framework, DCOM IPv6 application porting tools and guidelines Applications support IIS 6.0, IE 6.0, Windows Media Server & Client, File Sharing (Windows 2003), DNS Server (client on Windows 2003) MSN Messenger file sharing 3 Degrees Built on P2P SDK and requires IPv6 connectivity

13 Microsoft IPv6 Deployment Native v6 indicated by circles Also in Cambridge, U.K. ISATAP available in all buildings and all locations Native and ISATAP can communicate via ISATAP routers Microsoft publicly hosts Teredo servers on the Internet

14 Microsoft IPv6 Roadmap Now NextFuture Scenarios Developers: Peer to peer applications for consumers Developers: Peer to peer collaborative applications for knowledge workers Developers: Peer to peer and all core infrastructure Enterprise connectivity Anywhere access Remote management Mobility Client based transition: 6to4, Teredo NAT Traversal Public Teredo service Centralized transition: ISATAP/Teredo server Client based transition, now +: Firewall Traversal Full IPSec IPv6 Home gateways 6to4/Teredo relay Centralized transition : ISATAP/Teredo server Native adoption: Dual stack 6to4 IPv6 Home gateways 6to4/Teredo/Native Deployment methods Scenarios Deployment methods

15 IPv6 Partnerships Microsoft staff Communicate the IPv6 message Identify qualified customers Help IPv6 team to connect and engage dialogue with customers Provide feedback to the IPv6 team Become a Microsoft IPv6 expert Developers Investigate peer-to-peer and IPv6 as components for new development Develop IP-agnostic applications using new APIs Augment existing solutions with new capabilities Enterprises Deploy IPSec Deploy transition technologies Use IPv6-enabled equipment and applications for new deployments Reduce/Remove NATs Do not blindly block IPv6 traffic Service providers, carriers Deploy transition technologies Reduce/Remove NATs Use IPv6-enabled equipment for new deployments Conduct native v6 trials and provide native v6 connectivity Require IPv6 capability for new RFPs

16 Key Message: Don’t Wait Native IPv6 environment is NOT a prerequisite for achieving v6 benefits Application developers can use IPv6 NOW IPv4 will exist for a long time Tunneling technologies enable IPv4 and IPv6 to co-exist
