IoE => $14.4 Trillion Value
Three Business Cases for IPv6
Solving for CGN Going Mobile
69% Capex Reduction According to IDC report* for wireline
operators deploying IPv6 alongside CGN
*Free announces IPv6 to all
users by default. (Stockprice
up 300% since.)
Connecting the
Unconnected 50B+ devices by 2020
IPv6-only architectures for
the Internet of Things
“Fix the 15” “xlat464” technology allows IPv4 applications
to work on IPv6-only networks
T-mobile has
deployed 4 million
IPv6-only phones

The Internet Core is ready for IPv6 !
IPv4 transit AS’s: 9900 IPv6 transit AS’s: 1693*
IPv6 enabled AS’s: 3605
Concentrated in TOP 300
(82% of AS’s are IPv6 transit)
>30% CAGR

Example of ISP in US…
• Dual-Stack over DOCSIS 3.0
• DHCP-PD
• RHG IPv6 support ?
• 6rd fm RHG to CRS (BR)
• 6rd Over IPv4 DSL access
• Dual-Stack to 3G/4G handsets
• 3GPP Rel9, (ASR5000 Rel14)
• Mobile churn accelerates transition

and/or IPv6 SR
1. IPv6 addresses are, via correlated meta-data or bit-level semantics, a consistent, end to end, identifier throughout
the network that allows policy based decisions to occur anywhere needed.
2. IPv6 Addresses are not limited to one per device (each device may have many), and are not manipulated by NATs
3. IPv6 Segment Routing allow for Source routing/ Traffic engineering and Service chaining
4. Legacy IPv4 application can be supported via MAP, xlate464 and NAT64
x-late==IPv4oV6 for legacy apps
plate+NAT44: outgoing legacy

SA/DA route selection
IPv6 SR = Application Service Chaining

Key take away
oThe Internet is NOW a dual-protocol global communication system
o IPv6 users growing (fast) in (large) pockets
o Content is available on IPv6, but more needs to be done
o IPv6 is mature - Products are Ready - Services are available
o Start NOW: Plan, Deploy IPv6 per default
o IPv6 Centric - Next phase of IPv6 adoption
o End to End restoration and extension
o Service differentiation while Scale, Simplification/Automation
o IPv6 Centric dovetail incredibly well with NfV/SDN
o Highly Suitable for Mobile and MSDC/Cloud
o Mandatory for IoE, Scale, simplicity
