  1. IPv6 based NGN(NGNv6) CJK 7th Plenary: NGN-WG (IPv6 based NGN)

  2. Contents • Definition • Why need IPv6 based NGN? • Requirements and Architecture • Conclusion

  3. Definition • A Next Generation Networks (NGN) is a packet-based network able to provide Telecommunication Services to users and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent of the underlying transport-related technologies.

  4. Characteristics • The NGN is characterised by the following fundamental aspects: • Packet-based transfer  • Support for a wide range of services, applications and mechanisms based on service building blocks (including real time/streaming/non-real time services and multi-media) • Broadband capabilities with end-to-end QoS and transparency • Interworking with legacy networks via open interfaces • Generalised mobility • Unfettered access by users to different service providers • A variety of identification schemes which can be resolved to IP addresses for the purposes of routing in IP networks  • Unified service characteristics for the same service as perceived by the user • Converged services between Fixed and Mobile networks • Independence of service-related functions from underlying transport technologies • Compliant with all Regulatory requirements, for example concerning emergency communications and security/privacy, etc.

  6. 2. Why need IPv6 based NGN Overall Future Directions

  7. 2. Why need IPv6 based NGN Vision of Next Generation Ubiquitous Networking • Always on with Any devices • Anytime, anywhere and in any form • Voice and multimedia • Self service, intuitive • Simple for the end user • Secure, trusted and reliable

  8. 2. Why need IPv6 based NGN IPv6 Drive • Ubiquitous network • Grid networking • Mobile computing • Integration of Wireless and Wireline • Home Appliances • Peer-2-Peer applications • Virtual Private Networks • Multi-user gaming • Internet-enable new devices • Military applications

  9. 2. Why need IPv6 based NGN Relationship between NGN and IP • NGN, by definition, is identified an infrastructure using packet technologies. • There is no specific mention which packet technology NGN should use, but generally assuming IP as a dominant packet technology today. • There are also no specific statement to specify the version of IP such as ‘version 4’, ‘version 6’ or ‘version 9,’ but most parts of NGN related ITU-T RECs are mainly assumed ‘version 4’

  10. 3. 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 Configuration of IP based Networks

  11. 3. Definition and Scope Scope of IPv6 based NGN Scope of IPv6 based NGN

  12. 4. Requirements and Architecture Architecture of IPv6 based NGN

  13. 5. Conclusion Combination of IPv4/IPv6 based NGN • Continue to develop NGNv6 related Recs. • Specify Service and Functional capabilities of NGNv6 • Develop NGNv6 based interworking Voice FMC IPTV MM USN Full-CAR Net-Rob Managed IP IPv6 based IPv4 based Converged Broadband (Fixed+Mobile)

  14. 5. Conclusion ITU-T Plans for IPv6 based NGN • ITU-T SG13 has been developed framework recommendations of IPv6 based NGN. • The concept and requirements of IPv6 based NGN will open one of the important gateway to use IPv6 technology/systems under the umbrella of NGN. • According to the shortage of IPv4 based address which also impact to the NGN deployment, IPv6 should be used more widely. • In addition, ‘Ubiquitous Networking’ will require more addresses and flexible but device/object targeted management which would be benefited from IPv6 features .
