  • Every 7-10 years, technology delivery undergoes a tectonic shift; one that opens up new business and access models. A shift that changes the way technology is consumed and the value that it can bring. A change in what is possible. A removal of inhibitors that unleash the power of innovation. Today, mobility, social, big data, and the advent of cloud computing are representative of such shifts offering a new means for IT to help organizations accelerate progress towards solving their most pressing challenges (including speeding innovation, enhancing agility, improving financial management). These shifts can unleash the power of IT to not only support but help shape the business.
  • Now let’s review what the analysts are saying.In 2012, about 2.4 billion people around the world are online, out of a global population of 7 billion. In just five more years, that will rise to about 3.5 billion online users, according to Forrester.That is to say about half the Earth's estimated population in 2017 (7.4 billion).That means that about 1.1 billion additional people around the world will be online in the next five years, up from about 2.4 billion people who are online in 2012. Also remember that analysts also predicts that Number Of Mobile Devices Will Exceed World’s Population this year and industry expect 50 billion internet connected devices within the next 10 yearsOther realities are less than 25 % of Asia’s estimated 3.8 billion people currently have Internet connections (North America’s 78 % penetration rate)Even Gartner which has always been cautious are saying to enterprise customers:Enterprises must start upgrading their Internet presence to IPv6 now AND (of course) should choose a solution that can maintain both IPv4 and IPv6 for at least the next 10 years. Gartner Inc., 27 June 2012The Internet registrar in Asia/Pacific has run out of available IPv4 addresses, so enterprises must prepare now for the IPv6 Internet or suffer business impacts due to connectivity failures. Gartner Inc. 5 April 2012IDC is alsosaying The industry has reached a milestone with the exhaustion of IPv4 addresses. IDC believes that enterprise customers should have a transition plan in place to support IPv6 while continuing to support IPv4 across the infrastructure.IDC Market Analysis, 26 June 2012
  • Mobile operators may not be able to provide public IPv4 addressesCloud providers are not able to provide routable IPv4 addresses to customers
  • “IPv6, if properly configure, will enhance the enterprise security. If not, new security threats may arise”
  • Now let’s review an example.In this slide we show a typical IPv4 campus network.This network is divided into 3 layers. The access layer, the aggregation layer and the core layer.All devices in gray that you see on this slide are IPv4 onlyAnd the devices in blue are Dual stack IPv4 and IPv6 devices.Let’s see how we can enable access to the IPv6 based InternetNEXT SLIDE
  • We introduce IPv6 in the core layer by replacing core equipment with dual stack equipment.We then use dual stack switches in the access layer to allow dual stack devices to directly access dual stack core equipment.For devices which are dual stack in an environment where the access layer has not been transitioned you can then use mechanisms like host based tunnel like ISATAP or we could even use translation like NAT64 to allow IPv6 communicationBottom line is deploy dual stack first and supplement it with other transition technologyNow Let’s see in the next slide what kind of communication can occur
  • Here you can see that communication in orange are host based tunneling like ISATAPAnd communication in RED are IPv6 based communication
