The workshop in Kuala Lumpur on IPv6 deployment highlighted a significant increase in IPv6 readiness among various countries and organizations, with Belgium leading in capability at 46.24%. Different mobile network operators, including Verizon and T-Mobile USA, showcased successful IPv6 implementations and transition strategies. Observations indicated that while IPv6 deployment is growing steadily, it varies significantly across regions and individual operators, necessitating adaptive strategies for mobile networks.

19. Observations
• IPv6 deployment is increasing steadily
– But varies among regions, economies, and individual ASNs
– Not happening simultaneously
– Some economies and ASNs have been very active in terms of IPv6
deployment
• Particularly mobile network, cloud services and cable TV operators
• Regional smaller size operators shows higher level of IPv6 readiness
• Once they enable IPv6 in their network and handsets, their end user
readiness grows VERY rapidly
• It impacts to strongly respective economy’s IPv6 readiness level

24. Case study: Korea SK Telecom
• Deployed IPv6 transition technology (464xlat) in July 2014
– Providing IPv4 services over an IPv6-only network
• Stable operation
• Why did SKT adopt IPv6 in their mobile networks?
– To lower CAPEX for Network Address Translator (NAT)
– To reduce pressure on CGN/NAT address translation devices
– To reduce operational complexity on managing duplicated networks
– Korean government’s encouragement

19/10/2015: IPv6 capable = 89.96

26. Case study: Verizon Wireless
• Deployed DS network in 2012
• Why did Verizon Wireless decide to deploy IPv6?
– IPv6 allows VZW to provide globally routable addresses again
• No more NAT
• High quality connection
– IPv6 allows VZW to support accelerated growth of mobile
• VZW made a conscious decision to support IPv6 as part of
LTE deployment
– LTE core addresses using IPv6
– Dual Stack support on LTE User Equipment

http://stats.labs.apnic.net/ipv6/AS21928 20/10/2015
19/10/2015: IPv6 capable = 75.46

28. Case Study: T-Mobile USA
• Lack of IPv4 address space combined with rapid growth in “always-on”
devices prompted a re-think on IP addressing strategy in late 2009
– IPv4 does not fit the business need
– IPv6 deployment in 3GPP is easy
• Feasibility study and impact assessment on IPv6 deployment took
about 9 months
– Introduction feature to handsets is a slow and careful process
• T-Mobile USA started an IPv6 friendly user trial in 2010 on their 2G/3G/
HSPA network
– Settled with IPv6-only + 464xlat transition technology to make everything work
with IPv6-only
• T-Mobile USA did not spend any CAPEX to deploy IPv6
• End users will be assigned with IPv6 as a default
– No IPv4 addresses will be assigned

29. IPv6 for mobile network operators
• Verizon: deployed Dual Stack network in 2012
• T-Mobile USA: deployed 464XLAT in 2013
• SK Telecom: deployed 464XLAT in 2014
• Telstra Australia: Testing 464XLAT currently testing
• Telenor Norway
• Orange Poland

30. Observation on
464xlat
• Transition mechanisms like 464xlat work and can boost
IPv6 capability in the right circumstances
– Android devices show remarkably high, consistent level of IPv6
capability
– Will not make sense for a company with large iOS handset
deployment at the moment
• With Google, Facebook, Cloudflare, Akamai now routinely
supporting dual-stack content
– It is likely a significant % of traffic flows over IPv6 and reduces
pressure on the CGN/NAT requirement for IPv4
• Helps to avoid pitfalls of legacy IPv4-only broadband
deployments

31. iOS and 464xlat
• Apple made a decision (June 2015) NOT to implement
464xlat mechanisms
– iOS devices on a IPv6 cellular network do not support 464xlat.
• Therefore where there is significant iOS deployment,
464xlat excludes iOS
• Can we see this?

32. T-Mobile
• We know T-Mobile USA deployed 464xlat
– Pure IPv6 with translation for IPv4
• It’s predominantly a Cellular provider with some WiFi
services
• It should have a strong signal of IPv6 capability
– With no significant iOS usage

43. Conclusion

44. Mobile networks
• The business competency of mobile network operators:
– Shifting from being a traditional voice and messaging provider to a
mobile broadband service provider
– Services on voice, messaging and data are converging on IP based
services
– Rapidly increasing LTE deployment in the region
• Decision makers’ (mobile network operators) view
– Ready to move to Voice over LTE?
– Mobile cloud computing on top of the LTE network?
– What are key building blocks for all-IP strategy?
– What is your strategy to be innovative in the future – IoT?
