Why this draft ?

• As IPv6 is deployed, there are some problems that
  the application developers and the administrators
  face.
• This draft clarifies the problems occurred in
  transition periods between IPv4 applications and
  IPv6 applications.

What is problem ?

• Dual stack host does not mean having both IPv4
  and IPv6 applications.

What is problem ? (cont.)

• We cannot know the version of peer application

What is problem ? (cont.)

• We have three types of IPv6-enabled applications.
• IPv4BIA
• IPv6 native
• Both IPv4 and IPv6 support
• Application selection problem
• System administrator can be confused by various
  combinations of application versions and Ngtrans
  mechanisms.

Next Steps

• We need consensus on these problem statements.
• Are there any other problems or issues for
  application transition now, and in the future ?
• Do we need guidelines for application transition
  ?
• This draft will propose guidelines to implement
  and choose the suitable application under the
  various current transition environments.
• Become a ngtrans project.
