1. Why need IPv6 based NGN?

• NGN is based on packet now explicitly IP
• Specific IP version is not explicit generally
  IPv4 assumed
• Most of requirements and features are look like
  based on IPv4, no descriptions for IPv6
  related specific features
• IPv6 has different features than IPv4

1. Why need IPv6 based NGN?

• Different features between IPv4 and IPv6

2. Definition and Scope

• Definition of IPv6 based NGN

• IPv6-based NGN This is a NGN which support
  addressing, routing protocol and mechanisms of
  IPv6
• IPv4-based NGN This is a NGN which support
  addressing, routing protocol and mechanisms of
  IPv4
• IPv6-based Non-NGN This is an IPv6 based packet
  network which is not comply with NGN
• IPv4-based Non-NGN This is an IPv4 based packet
  network which is not comply with NGN

4. General Requirements

• General requirements of IPv6based NGN are
  identified requirements which influenced by IPv6
  features
• IPv6 based NGN shall share NGN R1 requirements
  generally
• Further requirements according to IPv6 features
  identified as IPv6 requirements
• IPv6 related requirements would be incorporated
  into NGN R2 requirements

General Requirements of IPv6 based NGN

• IPv6 based NGN shall accommodate the IPv6
  addressing schemes.
• IPv6-enabled FEs should differentiate the
  control information from the IPv6 packets.
• IPv6-based NGN shall support the address
  transition and interworking without affecting
  the service provided to users.
• IPv6-based NGN shall support the IPv6 extension
  headers and options.

6. Conclusion

• Q 9/13 slightly change its study direction at the
  Seoul meeting
• It was study on Impacts of IPv6 into NGN
• But now Q9/13 identified IPv6 based NGN as one
  of NGNs Y.ipv6-NGN
• This is much clear approach to identify impacts
  of IPv6
• Other drafts based on this will be followed

• Y.ipv6multi Framework of Multi-homing in
  IPv6-based NGN
• Y.ipv6sig Framework to support QoS Signaling
  for IPv6-based NGN
• Y.ipv6transit Functional Requirements for
  IPv4/IPv6 Migration in NGN
