- 3. NTT’s Pre-commercial IPv6 Service in the US
In June of 2003, NTT Communications launched pre-commercial
IPv6 service in the US
Native IPv6 was available in three locations
Bay Area
Los Angeles
Washington D.C. Area
Cisco 7206 routers in these three locations running dual stack -
tunneling across the backbone (backbone not dual stack)
Tunneling (RFC 2893 manually configured IPv6 over IPv4)
available in all other POPs (tunnel built to one of the locations above)

- 4. Pre-commercial Service Objectives
Pre-commercial service was offered from June 2003 to
December 2003
(at which time commercial service was launched)
Pre-commercial objectives
Bring on a small, manageable number of customers
Test provisioning and support procedures
Train NOC staff
Finalize JunOS/IOS IPv6 testing
Develop internal tools
Allowed time to upgrade backbone to dual stack
Still just a few dual stack routers with tunneling across the
backbone everywhere else

- 5. NTT’s Commercial IPv6 Service Launch
In 4Q2003 global backbone was AS2914 core completely dual stack
upgraded to dual stack (globally)
(Asia, Australia, North America, and Europe)
7x24 NOC support and SLAs
In December, 2003, three types of
IPv6 service were offered on a Still service functionality gaps
commercial basis
Native IPv6 (available at every POP)
Manually configured IPv6 over
IPv4 tunneling
Dual stack IPv4/IPv6

- 6. IPv6 Follow Up Releases
Since the commercial launch in December 2003, follow up releases have
been pushed out to fill functionality gaps
Added IPv6 support for
Off-net Tunneling
Managed Router Service
Shadow support for TDM and Ethernet
Managed Firewall
Dual stack Virtual Private Server
Our goal and philosophy is to offer all
features and services in IPv4 and IPv6

- 8. IPv6/IPv4 Dual Stack Backbone
IPv6/IPv4 Dual Stack Backbone has shown excellent
performance with no critical problems so far
Core routers / routing protocols have had no problems
handing IPv6 traffic (in addition to the IPv4 traffic/routing)
But still, we have some operational gaps
Stats tools are still lacking in the IPv6 environment (IPv6 MIB
support, SNMP over IPv6 support…)
IPv6 jitter measurement system compatible with our IPv4
system
Limited netflow v9 collector support
Firewall and Load-Balancer support is immature for Data
Center applications

- 9. Current Issues
Routing technology is “IPv4 with more address space”
Does not address routing architecture changes necessary to address expansion of
the Internet routing table
IPv6 policy solution to slow routing table growth makes it difficult for customers to
multi-homed
We need a solution to the multi-homing issues before IPv6 will be widely
adopted
Not seeing a huge demand from our customers yet
Current customers are mostly research oriented
OMB “mandate” not leading to many new customers

- 10. What Will Finally Drive IPv6 Deployment?
IPv4 Address Depletion
IPv6 is one solution to address a shortage of IPv4 address space
This problem is more critical outside the U.S. where IPv4 address space is
historically more limited
Current projections put IPv4 exhaustion at the IANA level at September 2011
New Applications
Next generation network applications will require ubiquitous network access from a
wide range of devices
IPv6 provides address space to uniquely identify these new devices and better end-
to-end security to ease the deployment of these new services
We see new network applications as the most likely driver of IPv6 deployment
