  • IPv6 Update Windows ® Networking & Communications Microsoft Corporation
  • Agenda
    • Enabling new engaging experiences
    • Today’s networking challenges
    • IPv6 and transitional technologies
    • Microsoft’s IPv6 status and roadmap
  • 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!
  • 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
  • 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
  • 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…
  • IPv6: Where is the Market Today?
    • “ In 2005, all Sony products will be IPv6-enabled.”

  • 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
  • v4/v6 Co-Existence Strategy 6to4 ISATAP Router 6to4 Router 6to4 Router 6to4 Relay ISATAP Teredo Relay 6to4 Relay 6to4 IDG v4 Internet NAT v6 v6 v4+ISATAP Enterprise 6to4 v6 Enterprise v6 v6 NAT Native v6 Enterprise v6 Teredo v4 Enterprise V4-v6 Dual Stack Enterprise v6 Internet
