Conclusion Contents Definition A Next Generation Networks (NGN) is apacket-based network able to provideTelecommunication Services to users andable to make use of multiple broadband,QoS-enabled transport technologies and inwhich service-related functions areindependent of the underlying transport-related technologies. Characteristics The NGN is characterised by the following fundamental aspects: Packet-based transfer Support for a wide range of services, applications and mechanisms based onservice building blocks (including real time/streaming/non-real time servicesand 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 forthe 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 transporttechnologies Compliant with all Regulatory requirements, for example concerningemergency communications and security/privacy, etc. Internet ISP ISP( )User ( ) IPv4 Packet Sender = Receiver = IPv4 Packet Sender = Receiver = IPv4 Packet Sender = Receiver = IPv4 Packet Sender = Receiver = IPv4 Packet Sender = Receiver = IPv4 Packet Sender = Receiver = Key Feature of IPv6 Overall view of using IP 2. Why need IPv6 based NGN Overall Future Directions 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 2. Why need IPv6 based NGN Vision of Next Generation Ubiquitous Networking 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 IPv6 Drive 2. Why need IPv6 based NGN 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 2. Why need IPv6 based NGN Relationship between NGN and IP 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 3.

Requirements and Architecture Architecture of IPv6 based NGN IPv6 signaling Traffic class, flow label, extension header 4. Requirements and Architecture Architecture for signaling of IPv6 based NGN (Y.2054) 4. Requirements and Architecture Relationship with other networks Continue to develop NGNv6 related Recs. Specify Service and Functional capabilities of NGNv6 Develop NGNv6 based interworking Converged Broadband (Fixed+Mobile) Managed IP IPv6 based IPv4 based Voice FMCIPTVMMUSN Full-CAR Net-Rob 5. Conclusion Combination of IPv4/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. 5. Conclusion ITU-T Plans for IPv6 based NGN
