IPv6 in North America

IPv6 in North America

• North American Global IPv6 SummitJune 24-27 2003
  
• Tony Hain
• Technology Director - IPv6 Forum Technical
  Directorate
• Technical Leader - Cisco Systems

Introduction

• Perception is that "IPv6 has not taken hold
  strongly within North America"
• IPv4 address space is less of a problem there
  than the rest of the world
• Private sector requires a business case
• Activities hint at change
• Test beds and early adopters increasing
• Wireless infrastructure emerging
• Industry and Government are looking at the
  operational advantages
• Increasing allocation of production global
  addresses

The pervasiveness of IT is inevitable

IP Address Allocation History

• 1981 - IPv4 protocol published
• 1985 1/16 of total space
• 1990 1/8 of total space
• 1995 1/3 of total space
• 2000 1/2 of total space
• 2002.5 2/3 of total space
• This despite increasingly intense conservation
  efforts
• PPP / DHCP address sharing NAT (network
  address translation)
• CIDR (classless inter-domain routing) plus
  some address reclamation
• Theoretical limit of 32-bit space 4 billion
  devicesPractical limit of 32-bit space 250
  million devices (RFC 3194)

IPv6 Prefix Allocations

Vendor status

• Most networking equipment vendors already ship
  IPv6 capable products
• Operating system vendors officially support IPv6
  in their latest product releases
• 2003 and beyond call for APPLICATIONS
• Applications must be IPv4/IPv6 version agnostic
• Successful deployment is driven by applications

7
Deployment activities

• 6bone RD network
• 185 sites registered including academia,
  government, research labs, vendors, and ISPs
• Planned phase out for cease of operations by July
  1, 2006
• Academia Research communities
• National and regional infrastructures are
  gradually moving to dual stacks, downstream
  sites are in the planning stages
• International partnerships in process
• Consumer
• Applications and appliances are emerging this
  year
• Substantial availability over next 18 months

8
Deployment activities

• Government
• Early adopters running IPv6 networks
• Leading target for IPv6 promotion (NAv6TF) with
  IPv6 called out for examination in National
  Strategy to Secure Cyberspace
• Operational networks require validation process
• Enterprise
• Minimal deployment beyond vendor development
  networks
• Learning curve in architecture and management
  groups
• Deployment gated by application and O.S. upgrade
  strategy

9
Deployment activities

• Exchange points
• 6tap, 6IIX, NY6IX, PAIX, S-IX(NTT San Jose),
• ISP
• Plans are largely driven by customer demand
• Lack of explicit demand???
• Trial networks are up and running
• CW, Hurricane, MCI, Qwest, Sprint, Stealth,
  Verio,
• Clear lack of consumer services
• Dial, DSL, Cable, FttH,
• Return on investment (RoI) justifications sought
• Particularly in the current economic environment

10
Deployment activities

• Wireless
• U.S. wireless service providers finding it
  difficult to create a viable business plan under
  the limited growth IPv4 allocation policies
• Some are currently investigating IPv6 as a way
  forward, with projected phases of RD ('03),
  Trials ('04-05), Production deployment ('06)
• Several 802.11 Hot Spots already offer IPv6
  connectivity service

11
Deployment concerns

• Applications
• Upgrade availability, certification timeframe,
• Network Management availability
• Provisioning, billing, management stations,
  operator training,
• Security
• Maturity of filtering intrusion detection
  devices vs. IPv4
• Potential new avenues of attack, and transition
  interactions
• IPv6 deployment costs Return on Investment
  (RoI)
• Software/hardware upgrades, training,
• Business models for new appliances, applications,
  and services

12
Summary

• ARIN is actively allocating IPv6 prefixes
• Deployment activities are quietly underway
• Successful deployment is driven by applications

North-American IPv6 Task Force (NAv6TF)

• Similar in charter to the other IPv6 Forum
  regional task forces
• Mission To help promote and foster IPv6 adoption
  within target industries through Short Long
  Term Objectives and Deliverables
• Recently, NAv6TF sent its recommendations to the
  U.S. Presidents Critical Infrastructure
  Protection Board regarding the National Strategy
  to Secure Cyberspace
• Meeting at U.S. Global IPv6 summit June 2003
• IPv6 Demonstration Collaborative initiative
