18. IPv6 for eBusiness www.ipv6.org.au 18 IPv6e-B Project Activity 2 Enabling 2.1 Business Case Scenarios 1.The 'do nothing' case 2.It's inevitable, may as well go with the flow 3.Competitive differentiation 4.Competitive protection 5.Return on investment 6.Known opportunities - understood and tangible 7.Unknown opportunities - preparing fertile ground

19. IPv6 for eBusiness www.ipv6.org.au 19 Business Case 1 – Do Nothing 2.1 'Do nothing' case All scenario studies should start with the 'do nothing' case. IPv6 was developed with a strong design goal of being backwards and forwards compatible. In a broad sense, the only applications or network communications that will 'break' are the cases where they are deliberately designed to do so. Applications specifically written for IPv6 may not work as effectively or at all in an IPv4 world. One may not be disadvantaged in the short to medium term by not adopting IPv6, however there will be increasing examples of functional benefits that will be denied to non-IPv6 users.

20. IPv6 for eBusiness www.ipv6.org.au 20 Business Case 2 – It’s Inevitable 2.2 It's inevitable, may as well go with the flow There is a certain inevitability to the IPv6 juggernaut. Overseas government departments are being mandated to use or make provision for IPv6 in reasonably short timeframes (Japan 2003, Switzerland 2005, Europe 2006, Korea 2006, USA 2008). Other countries such as China, Taiwan, the UK and Germany are actively integrating IPv6 planning into their strategic IT scenarios.

21. IPv6 for eBusiness www.ipv6.org.au 21 Business Case 3 - Differentiation 2.3 Competitive differentiation IPv6 offers opportunities to differentiate service offering from competitive offerings. At a superficial level, this might include straight connectivity options - IPv6 web sites that are hidden from non-IPv6 users. More substantially, IPv6 offers advantages in security, authentication, and enhanced trust relationships that may allow a tiered service offering based on a rich set of customer/consumer Quality of Service parameters. The increased security and functionality afforded by IPv6 can be parlayed in many different marketing messages.

22. IPv6 for eBusiness www.ipv6.org.au 22 Business Case 4 - Protection 2.4 Competitive protection As competitors increase their use of IPv6, others may be forced to comply to be seen to be compatible - this is the counter point to competitive differentiation. There will be cases where B2B, Extranet, social networking or other loose collaborative interactions may demand IPv6 compliance just to be allowed to participate. It may be that non-IPv6 authentication or access will not be acceptable. Microsoft's Windows Collaboration (also known as Windows Meeting Space) application in Windows Vista and Longhorn Server uses IPv6, so you must have IPv6 installed and enabled on your network adapter to use WMS. IPv6 is installed and enabled by default in Windows Vista. Staying competitive with our trading partners and neighbouring countries will increasingly dominate Australia's geo-strategic thinking. Australian industry will not be able to sell into advanced markets as they will lack an intimate and comprehensive appreciation of IPv6 networking. We may also become the dumping ground for obsolete IPv4 hardware and software applications.

23. IPv6 for eBusiness www.ipv6.org.au 23 Business Case 5 - ROI 2.5 Return on investment The return on investment for IPv6 adoption follows a similar profile to any other IT project. The IPv6 for eBusiness project developed ROI tools based on an Excel spreadsheet that can be used to calculate the NPV (net present value), ROI (return on investment) and payback periods, typically over a 15 year period.

24. IPv6 for eBusiness www.ipv6.org.au 24 Business Case 6 – Known Issues 2.6 Known opportunities - understood and tangible There are many cases where interoperability is a paramount requirement and current arrangements for addressability, security and compatibility need to be enhanced. Disparate entities are thrown together for short and longer times and need to interoperate. –E.g., emergency services respond to a natural disaster. The Fire, Police, Ambulance, rural fire authorities, SES, government departments, Utilities, Railways, Defence personnel and many others are thrown together with little opportunity for planning. –IPv6 based networking is increasingly used internationally to allow interoperability between these services on an ad hoc basis.

25. IPv6 for eBusiness www.ipv6.org.au 25 IPv6e-B IPv6 Known Opportunities are supported by the protocol’s unique technical properties …explored in more detail on the ipv6.org.au website and can be summarised as…

26. IPv6 for eBusiness www.ipv6.org.au 26 IPv6 - Unique Attributes 6.1 Vastly increased address space –Extending the 4 billion IPv4 address space to the 3.4 x 10^38 IPv6 address space allows many existing and new processes to receive addresses. –It has been said that in the future, any device worth more than $10 will have at least one IP address and be networked (source: Dr. Dean Economou, CENTIE 2002). Are we there yet?

27. IPv6 for eBusiness www.ipv6.org.au 27 6.2 Fixed 40-byte headers –IPv4 packet headers vary in size depending on the attributes that are assigned - they are typically around 20 bytes. –With IPv6, a significant rationalization has taken place such that the IPv6 header is now a fixed 40 bytes. –Although this is approximately twice as big, the advantage of a fixed versus variable header cannot be understated. IPv6 - Unique Attributes

28. IPv6 for eBusiness www.ipv6.org.au 28 IPv6 Header – Comparison with IPv4 128 bit Source Address 128 bit Destination Address bit 0 31 Version IHLTotal Length IdentifierFlagsFragment Offset 32 bit Source Address 32 bit Destination Address 82416 Service Type Options and Padding Time to LiveHeader ChecksumProtocol 31 Version ClassFlow Label Payload Length Next Header Hop Limit 4122416 IPv4 Header 20 octets, 12 fields, including 3 flag bits + fixed max number of options IPv4 Header 20 octets, 12 fields, including 3 flag bits + fixed max number of options IPv6 Header 40 octets, 8 fields + Unlimited Chained Extension (options) Header IPv6 Header 40 octets, 8 fields + Unlimited Chained Extension (options) Header Removed Changed bit 0

29. IPv6 for eBusiness www.ipv6.org.au 29 6.3 Autoconfiguration –Autoconfiguration is the automatic configuration of devices without manual intervention, software configuration programs or jumpers, and devices should just "Plug and Play". –This process also includes duplicate address detection, multihoming and other useful network administration activity. IPv6 - Unique Attributes

30. IPv6 for eBusiness www.ipv6.org.au 30 IPv6 - Unique Attributes 6.4 Default IPsec Security –IPv4 was developed at a time when Security was not uppermost as a concern. –Authenticating protocols such as IPsec were developed later and need to be retrofitted into IPv4 protocol stacks. –Conforming standards- based IPv6 protocol stacks have IPsec as a mandatory requirement.

31. IPv6 for eBusiness www.ipv6.org.au 31 6.9 Flow Label QoS –All of the Differentiated Services (DiffServ) and Integrated Services (IntServ) Quality of Service attributes from IPv4 are carried over into IPv6. –In addition, IPv6 exclusively has a 20-bit Flow Label field. –This field is being developed to provide a rich set of Quality of Service attributes for the growing IPv6 world. IPv6 - Unique Attributes

32. IPv6 for eBusiness www.ipv6.org.au 32 6.5 End to end trust –Network Address Translation (NAT) has broken the end to end trust that was a hallmark of early IPv4 services. –Authenticated IPv4 Internet connections stop at these NAT gateways. –Authenticated IPsec IPv6 sessions will route from end to end. IPv6 - Unique Attributes

33. IPv6 for eBusiness www.ipv6.org.au 33 6.6 Attribute Extension Headers –To conserve space in the IPv6 packet header, a series of Extension Attribute packets have been defined. –This vastly speeds up the router packet forwarding rates and improves the efficiency of the communications sessions. IPv6 - Unique Attributes

34. IPv6 for eBusiness www.ipv6.org.au 34 6.7 Anycasting –Anycasting was a unique attribute of IPv6. –In IPv4, only Unicast and Multicast addressing was originally supported. But you can’t keep a good idea down… –Anycast addressing refers to a single source calling a predetermined list of Anycast destinations, but only one destination responds and participates in subsequent transmissions. IPv6 – ‘Unique’ Attributes

35. IPv6 for eBusiness www.ipv6.org.au 35 6.8 MobileIPv6 –When a device moves from its home network, its IP address and gateway address will be recognized as a foreign address in its new location and will be denied service. –To overcome this limitation, a process called MobileIP was developed in IPv4. This consisted of the devices calling 'home' and telling the home network of its changing gateway environments (the foreign correspondent model). –In MobileIPv6, a foreign correspondent server is continuously updated as to the network the device is in and which gateway to use to reach the travelling device. –This vastly improves performance and reliability, and reduces cost. IPv6 - Unique Attributes

36. IPv6 for eBusiness www.ipv6.org.au 36 Business Case 7 - Unknowns 2.7 Unknown opportunities - preparing fertile ground –the Internet is now a mainstream activity Compared with only a short time ago, whole armies of engineers, entrepreneurs and programmers are dedicating their professional lives to exploiting the capabilities of the Next Generation IP. –New and innovative enhancements are being made every day to the Internet Protocol Suite. It can be anticipated that unforeseen and innovative applications will continuously come into being. Students being taught IPv6 protocols today will continue to find opportunities to express themselves in new and challenging ways as they graduate into the workforce. –IPv6 protocol suite is not a closed system. Using the open framework approach of Extended Attribute packets, IPv6 is an extensible protocol that has no practical limits. –IPv6 is uniquely positioned to support new and innovative applications such as Peer to Peer (P2P), Sensor Networking, GRID and Ambient Intelligence. –It is the platform both of the Future, and for today.

39. IPv6 for eBusiness www.ipv6.org.au 39 IPv6e-B Return On Investment Tool

40. IPv6 for eBusiness www.ipv6.org.au 40 IPv6e-B Return On Investment Tool Worked Example We consider a hypothetical mining operation with 2000 personal computers, 400 trucks for ore haulage and a total of 20 IT staff paid, on average, $114K per year. The operation sees the benefits to be derived from transition to IPv6 as follows: –About 6% of its IT staff are involved in managing NATs and ensuring the interoperability of applications with NATs. This costs around $150K per year, or $75 per PC per year and can be essentially eliminated almost immediately by use of IPv6. –The use of IPv6 will also allow great improvement in real-time two way communication with the truck fleet as it operates. A transponder system will become operational a couple of years after IPv6 is enabled. This is seen to have 3 main benefits: maintenance costs will be reduced by an estimated 1% from the current $100K per truck per year, a saving of $1K per truck per year; truck replacement, at a cost of $160K per truck, will be delayed for an additional year, extending the current 3-year replacement cycle to 3.3 years, a saving of $7.6K per truck per year; and enhanced scheduling is expected to improve throughput and add $516K to the mine's pre-tax profit ($1.29K per truck per year). –Finally, the organisation expects to improve IT security. On average, the organisation has incurred security costs of $300K per year ($0.15K per PC), mainly due to virus attacks and unauthorised access. (The loss due to data theft is not known.) It is believed that the improved security protocols enabled by IPv6 will reduce the frequency of security breaches by 70%; but it will take a few years before these can be introduced.

44. IPv6 for eBusiness www.ipv6.org.au 44 IPv6e-B Project Activity 2 Enabling 2.3 Transition Issues Organisations planning to test or deploy IPv6 would usually follow the phases below to ensure a non-disruptive transition: Start off with a pilot project, testing IPv6 on existing IPv4 networks. Run separate IPv4 and IPv6 networks on the same infrastructure. Transition to networks with 'dual-stack' IPv4 and IPv6 devices. Finally move fully to IPv6 networks, with legacy IPv4 phased out over time. For each of these phases, most organisations will need to follow a similar series of steps: Assess business requirements, risks and benefits Survey existing network infrastructure Educate technical staff professionally Resource network and security infrastructure Phase-in and test IPv6-capable devices Inform and set policies for general staff Monitor and maintain procedures and infrastructure
