2. IPv6 benefits and drivers

3. Generic Benefits of IPv6
Key benefit – increasing address space
IPv4: 32-bit, ~ 4.3 billion addresses
IPv6: 128-bit, ~ 340 undecillion addresses (3.4x1038)
Other advantages
Auto-configuration via neighbor discovery
Mobility
Better routing efficiency and flexibility
Six fields removed
Extension header added
IPSec is mandatory
Performance improvement for broadband utilization
Jumbograms 4 GB (going to 32) in v6 vs. 64KB in v4
use flow label to largely increase the network utilization
QoS included in IPv6 headers
End to End (security, QOS)

4. Key Drivers for IPv6
Large address space is the most compelling reason for IPv6
IPv4 addresses limitation starts to restrict Internet growth and use, especially in China, India, and other heavily populated Asian countries
IPv4 address exhaustion has been predicted in less than 8 years
Government mandates: Japan, US, China…
Explosion of wireless IP devices
2 billion mobile phones by 2006, not enough with what is left today with IPv4
The urgency of providing IPv6 services in US
US Office of Management and Budget (OMB) government Mandate in 8/2005 “Federal agencies must use the next-generation Internet service known as Internet protocol version 6 (IPv6) by June 2008…”
Following the mandate, government agencies would need to upgrade their IPv4 VPNs to IPv6 VPNs by mid 2008

5. NGN and IMS

6. IMS in a nutshell What is IMS? What else is IMS?
UTRAN
GERAN
WLAN
CDMA2000
WCDMA
Access network

IMS
Internet
CS domain
PS domain
What is IMS?
IP Multimedia Subsystem
A technology that enables exciting multimedia services
Part of the core network, with interfaces to subsystems in the 3G network
A group of specifications being standardized by the 3GPP
What else is IMS?
An architecture for service and call control
One network can easily serve roaming subscribers
Designed to be flexible, robust, and secure
Can easily introduce new Internet nature services and capabilities

No NATs in between, public IP addresses are needed
Thomas
Peter
Example services: gaming, chat, streaming, Voice/video over IP, etc.
The SIP/IMS user plane is peer-to-peer in nature - SIP/IMS sessions between mobiles in different Private IPv4 address spaces become highly complicated. This is why public IP addresses are required. The only future proof solution is provided by IPv6.

15. NGN Multimedia services – driving for IPv6
IPTV – Poor quality, high cost
No end to end quality control
Must send one stream for every customer -- $$$
V2oIP - Difficult to control quality
Triple/ Quad play
P2P/ M2M
global peer-to-peer services
FMC

16. NAT traversal in NGN – Ipv6 drivers
How about NAT (network address translation) ?
Management effort
Topologies and environment
SIP
Call setup time
End-to-end security
End-to-end QoS

17. NGN Key Drivers for IPv6
Large address space is the most compelling reason for IPv6
Cellular and wireless market is moving to IP
Mobility (MIPv6)
Better battery life
Better spectrum utilization
Fast Handover
Seamless mobility
QOE
Call setup time
NAT elimination

18. Summary and conclusions
IPv6 is behind the corner (technology, regulation)
All the NEP/ TEM vendors are already building & selling IPv6 enabled elements
New NGN development is done mainly for IPv6, but with support for IPv4
The migration to All-IP is the main driver for IPv6 benefits
