IPv6 Deployment Stages
IPv6 deployment approach of TM NGN highly depends
on the IPv6 readiness of terminals of end-users.

• IPv4 Islands with IPv6 Dominance

• IPv6 Islands with IPv4 Dominance

• IPv6 Network and IPv4 Network in equivalent shares

2009
2010
2011
2012

2013
Assumption is based on exhaustion of IPv4
addresses by Y2011 and exponential growth rate of
IPv6 CPE terminals being deployed for future
broadband services.
