IPv6 benefits and drivers
Generic Benefits of IPv6
Key benefit – increasing address spaceIPv4: 32-bit, ~ 4.3 billion addressesIPv6: 128-bit, ~ 340 undecillion addresses (3.4x1038)
Other advantagesAuto-configuration via neighbor discoveryMobilityBetter routing efficiency and flexibility
Six fields removedExtension header added
IPSec is mandatoryPerformance improvement for broadband utilization
Jumbograms 4 GB (going to 32) in v6 vs. 64KB in v4use flow label to largely increase the network utilization
QoS included in IPv6 headersEnd to End (security, QOS)
Key Drivers for IPv6
Large address space is the most compelling reason for IPv6IPv4 addresses limitation starts to restrict Internet growth and use, especially in China, India, and other heavily populated Asian countriesIPv4 address exhaustion has been predicted in less than 8 yearsGovernment 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 USUS 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

What is IMS?IP Multimedia Subsystem A technology that enables exciting multimedia servicesPart of the core network, with interfaces to subsystems in the 3G networkA group of specifications being standardized by the 3GPP
What else is IMS?An architecture for service and call controlOne network can easily serve roaming subscribersDesigned to be flexible, robust, and secureCan easily introduce new Internet nature services and capabilities

No NATs in between, public IP addresses are needed
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.

NGN Multimedia services – driving for IPv6
IPTV – Poor quality, high costNo end to end quality controlMust send one stream for every customer -- $$$

Summary and conclusions
IPv6 is behind the corner (technology, regulation)All the NEP/ TEM vendors are already building & selling IPv6 enabled elementsNew NGN development is done mainly for IPv6, but with support for IPv4The migration to All-IP is the main driver for IPv6 benefits
