The document discusses the critical need for IPv6 adoption as we approach 50 billion connected devices by 2020, emphasizing the limitations of IPv4 and the challenges of network address translation (NAT). It highlights the advantages of IPv6, including increased address space, improved end-to-end connectivity, and enhanced security for future applications. The text stresses the urgency for stakeholders to devise a cohesive IP migration strategy to facilitate a smooth transition to IPv6.

8. The evolution of IP
IP has an evolution path, lets not jump ahead. There will be
branches for sure, some will die and some will live on, time
will tell....
....so what to do to remain a surviver.

12. Obviously we can do IPv6! Yes wE(///) can!
Questions we need to ask ourselves:
› Why IPv6 for 50B?
› Is the 3GPP IPv6 architecture ready
for 50B and beyond?
› Do we have a IP migration strategy
with an acceptable exit strategy?

15. Why IPv6 for 50B?

16. Why IPv6 for 50B?
› More IP addresses – Restoring end2end to internet
– For billions of new devices (mobile phones, cars, appliances, sensors…)
– For billions of new users (China, India, Africa,…)
– Always-on access (mobile, cable, xDSL, Ethernet-to-the-home,…)
– For applications that are difficult, expensive or impossible to operate
through NATs (IP telephony, peer-to-peer gaming, home servers,…)
› Easier security
– End2end connectivity enables easy IPsec authentication, authorization and
encryption.
Remember: Security is a moving target

20. Upcoming 3GPP Standardization for m2m
› IMS architecture was once IPv6-only. Why?
– Huge # of terminals
– End2end communications model using SIP
› Is m2m any different?
– Can the industry agree that IPv6 is the baseline IP version for m2m
and not go through the pain of IMS IP version interworking again?
– Can we skip NATs? Hey, it s a new time, new place……

NOTE: IPv6 based addressing for both UEs used for MTC and
MTC Servers is considered the primary addressing solution and
is preferred to ensure future proof and scalable deployments.

21. 50B Keep-Alives

23. DAMN those Keep-Alives!

(hopefully, at least some, and oh, I forgot about in-path firewalls, pcp anyone?)
Toto, I ve got a feeling we re not in NAT44-land anymore…

30. Traffic growth with dual-stack
300.000
Network capacity need to grow to handle user traffic growth
Throughput Gbps
If Dual-stack is deployed IPv6 will increasingly offload IPv4 as
more services are also offered over IPv6 and NAT capacity
need will decrease, reducing NAT expansion need and
eventually reverse its need to grow == eliminate NAT Native
CAPEX and decrease OPEX IPv6
IPv6-only combined with NAT64 gives same result
and eliminates IPv4 private address usage at UE Native

applications and
dual-stack is possible ~40 Euro
with two PDP contexts

aggregated ”Internet of things” need to be studied further in
3GPP order to accomodate this huge market.

44. Do we have a IP migration
strategy with an acceptable
exit strategy?

45. Think and plan ahead!
› Take aim for IPv6-only!
› I you don t need to enter an IP
migration there s no need to exit!
› For 50B and beyond the important thing is
which IPv4 relics are left in the architecture.
(Compare the 1500MTU relic in Ethernet)

46. Conclusion 50B and IPv6
› We will get there… Resistance is futile.
› Go for IPv6 ASAP
› Get rid of the Keep-alives
› Aggregate connectivity
