IPv6 In the NGN market for multimedia services

1. IPv6 In the NGN market for multimedia services February 2007 Asher Shiratzky CTO TBU

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 Internet PS domain CS domain UTRAN GERAN WLAN CDMA2000 WCDMA Access network Terminals IMSin a nutshell 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

7. Where is IMS positioned? Wired DataNetworks Wired ConvergedIP Network Wired Voice & videoNetworks IMS Anytime, Anywhere Applications CellularVoice/ Video/ Data WirelessIP Network Wireless Wireless Networks All networks speaking the common language of IP Legacy networks

8.

9. Organization involved in IMS

10. Who will consume IP addresses • Cell/ IP/ Soft phones/ PDA • homer networks • Automobile • TV • STB • Surveillance/ Video cameras • Sensor Networking technology (RFID, etc.) • Gaming console • Services (Gaming, Gambling, PTx, …) IPv4 address space is limited !!!

13. Peter chooses to add a streaming component to share what he is seeing SIP Game data IP Connection Streaming video from Peter: Example of P2P IP connectivity CSCF IPv6 Streaming video Thomas Peter Invite player Peter: 00:00:00 Thomas: 00:00:00 Chat > Peter: hey, look what just passed by! Push to Stream Quit

14. Media components Signalling only Peter: 00:00:00 Thomas: 00:00:00 SIP Game data Chat IP Connection No NATs in between, public IP addresses are needed Example services: gaming, chat, streaming, Voice/video over IP, etc. Future mobile services = ”serverless media” CSCF IPv6 Thomas Peter 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
