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?
