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.
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.

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

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 .
