  1. 1. NTT Communications IPv6 Overview: Deployment & Commercial Applications Doug Junkins Chief Technology Officer NTT America 1 Proprietary and Confidential - © NTT America 2010
  2. 2. NTT America IPv6 Customer Profile IPv6 Customer Breakdown Education & Government 6% Hardware & Manufacturing 19% Internet & Telecom 64% Webhosting & Web Services 11% Total 100%  Approximately 20% of our customer  Approximately 40% of our peering ports are IPv6 enabled ports are IPv6 enabled 2 Proprietary and Confidential - © NTT America 2010
  3. 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) 3 Proprietary and Confidential - © NTT America 2010
  4. 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 4 Proprietary and Confidential - © NTT America 2010
  5. 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 5 Proprietary and Confidential - © NTT America 2010
  6. 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 6 Proprietary and Confidential - © NTT America 2010
  7. 7. Dual Stack IP Backbone – April 2010 Japan/US 320G US/Europe 60G Japan/Europe 27G Asia/Ociania 147G Highest quality global Tier-1 IP backbone Global IPv6/IPv4 dual stack network Fully redundant network backed by industry Shortest access between Europe and leading SLA’s Asia-Pacific available via new cable route 7 Proprietary and Confidential - © NTT America 2010
  8. 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 8 Proprietary and Confidential - © NTT America 2010
  9. 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 9 Proprietary and Confidential - © NTT America 2010
  10. 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 10 Proprietary and Confidential - © NTT America 2010
