IPv6 Update

• Windows Networking Communications
• Microsoft Corporation

2
Agenda

• Enabling new engaging experiences
• Todays networking challenges
• IPv6 and transitional technologies
• Microsofts IPv6 status and roadmap

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
Todays 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
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
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

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

Moving From v4 to v6

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

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
