IPv6 Deployment Ric Clark COO National ICT Australia
What is this talk about? • Not going to argue IPv6 technical virtues • Deployment drivers • Lessons from other technologies • Suggested actions
IP Infrastructure • IPv4 is an extraordinary success story • In excess of 200M users around the world • Catalyst for generating new services • IP infrastructure or the “Internet/Intranets” have become a strategic resources • Underpinned economic growth
Some Simple Statistics Users per 1000 people land lines, mobile and “broadband”
Trends The growth of the services on IP based infrastructure is dependent on: • A well developed physical infrastructure • Ability to identify the elements that are connected (addressing)
Physical Infrastructure • Communication lines/exchanges …. • Leveraged to provide data connectivity • Countries have been leveraging off the existing infrastructure • Also having targeted programs in investing in developing this infrastructure • Technological advances such as DSL technology has resulted in significant improvements • Therefore, it appears that the physical infrastructure is not a real impediment to the growth of IP services
Addressing • Addressing appears to be another story • This where the biggest arguments are taking place. • Will IPv4 do? Or do we need v6?
IP Address Allocations • There have been many studies • Geoff Huston • Myth of IPv6/IPv4 • How long do we have? • Potaroo • Latest by Tony Hain
Past 5 Year Assignment History Figure from CISCO white paper based on Hain
Holy Wars? • Data can be manipulated to suit a story • There could be linear approximations, polynomial approximations …… • Different set of data can also be used • For example Hain’s analysis is based on allocations, Huston’s analysis is based on use of addresses. • Re-allocation of unused address blocks towards the end can change the estimates.
It is not so cut and dried • IPv4 address space have been slowly depleting since the early 90s • The depletion has been slowed down • Due to technological innovations such as CDIR • Network Address Translators (NATs) • The the strict policies adopted by the registries (RIPE-NCC, ARIN, APNIC) responsible for global IP address allocations • CIDR has enables the use of unused alloactions • NATs have provided way of extending the use up of the addresses • These innovations and because the depletion does not exert overt economic pressures • It is difficult to justify investments in an IP upgrades to solve the addressing problem
However… • Fixes such as NATs have hidden costs • Managing those NAT devices is a complex and is time-consuming • NATs break the end-to-end principle of the Internet • Some applications, such as peer-to-peer, cannot work across a NAT device • Other applications, such as VoIP, require adding special code to the NATs • NATs complicate development of new services, e.g. skype. • More importantly what about the demand in the future • Mobile devices • China, India and later Indonesia, Bangladesh…… • “Developing countries” • Bring up to 20% connectivity will swamp the reaming pool
Common Sense View • Regardless of whether the address space will run out in 5 years or 10 years, all evidence seem to point to the fact that we will need a bigger address space • Lack of a common view though is the greatest barrier to deployment
Lessons from Other Technologies • Adoption rate growth • Next generations in cellular • Positioning by Standards bodies
Compelling Event • Who cares? • The sad truth…..not too many! So how do you address this?
What do CIOs Want? • Security • Web Services • Mobility and M2M • Risks Mitigated
IPv6 is the solution • To increase IP addressing space. • Incorporates improvements based on the lessons learned from operating IPv4 • stateless autoconfiguration • more efficient mobility management • integrated IPsec • These are the fundamental aspects of IP version 6 (IPv6) • So what not use it?
However…… • A very successful industry cannot be changed overnight • Deployment can only happen incrementally • One needs to ensure that there is no detrimental impact on IPv4 traffic in any way • Under these conditions the two key questions that need to be answered are: • Is it possible to justify investments in an IP upgrade ? • Can one ensure then the up-grade will not have adverse impacts ?
Easy One First • Can be easily done through phased Introduction IPv6 Promotion Council of Japan
Obstacles • There are three primary obstacles to this phased deployment: • People “don’t know how to implement it,” • “still feel uncertain about its stability and quality,” • Removal of the first barrier • Can be done by preparing deployment manuals for each user entity • Clarifying the deployment processes and security models • Establishing a metric for deployment • Removal of the second barrier • Verifying the reliability of IPv6 • Identifying design and operation bugs through demonstration experiments and evaluations • Already being done through projects like the 6 bone and the work societies like IPv6 Promotion Council of Japan IPv6 Promotion Council of Japan
Coordinated Promotion • We need some thing similar to: • European Commission's IPv6 Task Force or • Japan’s IPv6 Promotion Council • Include agencies, early adoptors, CIO’s etc.
Summary • Sooner or later it will be required • Don’t stop the technical debate but don’t let it stop deployment • Sell the Sizzle • Create a ‘promotions’ council
