  • 4. IPv6 – the New InternetInternet is running on “empty” 60% of World Population• Explosion of users, devices, connected appliances and applications• Virtualization and cloud computing Traditional Private and IT Public• IPv6 is already on a network close to you CloudIPv6 enables you to flip the ratio fromoperations to innovation More with less New IT project initiatives Needs BYOD to be Instant-On Ongoing IT operations INNOVATION OPERATIONS4 © Copyright 2012 Hewlett-Packard Development Company, L.P.

  • 5. Today’s RealityQuality of experience is evermore criticalMitigation techniques (like NAT) to Address sharing issueshandle the address pool depletion are • Amplification of security issues/ policing/ penalty boxesnow inherent as a dominant business • Traceability of network usage and abusage (for lawmodel enforcement)• Complexity pushed onto applications and content • Geo-location and geo-proximity services providers • Frequent NAT Keepalives reduce battery life • Address sharing application impacts Large Scale NAT NAT IPv4 Jason Fesler Yahoo! feb. 2012 Internet Private Private Public5 IPv4 © Copyright 2012 Hewlett-Packard Development Company, L.P.

  • 6. Today’s Reality – Security Is even more Critical Islands of IPv6 Security operational challenges • Complexity due deployment of IPv4 mitigation techniques • IPv6 is already present on your network • Very often unmonitored IPv6 • IPv6 deployed along IPv4 increases the size of the Internet attack vector IPv4 Internet6 © Copyright 2012 Hewlett-Packard Development Company, L.P.

  • 7. Not Just About the NetworkIPv6 has implications across the entire IT environmentEstablish a task force IPv6 traffic is already in your network now and uncontrolled When will you need IPv6 inside the DC? IPv6 is not onlyabout technology Will web enablement be your inflection point?Are your applications IP dependent? Many clients default and prefer IPv6 now7 © Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
  • 8. IPv6 Operational AdvantagesMuch more than just a larger addressing space • Robust, effective, efficient with unlimited address space • Extensibility, enhanced mobility • Optimized for next generation networks • End-to-end services and applications • Free manpower from ordinary tasks • Enable service automation • Better support for QoS • Policy driven operations • Free manpower from ordinary tasks • Rapid deployment Unlock the potential of IPv68 © Copyright 2012 Hewlett-Packard Development Company, L.P.

  • 9. Strategy to Achieve Transformational Benefits Unlock the potential of IPv6 Facts Current Evolution Future State • IPv6 is inevitable, what is your inflection point State Subproject • You control how and what role you want to play Desired State • If your business is reliant on the internet, IPv6 is a Create a Value of necessity Roadmap Strategy • Late start rapid deployments of IPv6 increases Likely Outcome risk and cost • Ignoring IPv6 introduces security risks Pain Points How will you • Content consumption is breaking down on IPv4 get there? • Instant connectedness is not possible with IPv49 © Copyright 2012 Hewlett-Packard Development Company, L.P.

  • 10. IPv6 Transformation JourneyJoint Business & IT Task Force ensures a smooth path toward IPv6 Often Customer overlooked Requirements Applications Yesterday’s thinking won’t reveal today’s opportunities Business Security Model • Determine how IPv6 affects all business units Business • Find ways IPv6 can help achieve your business and IT Infrastructure goals Goals • Analyze risks Business Network • Remember transforming IP dependent applications is Process time consuming task Value Proposition10 © Copyright 2012 Hewlett-Packard Development Company, L.P.

  • 11. Financial Impact • Planning and preparation costs Predictability$ • Investments for HW and SW IPv4 to IPv6 Transition costs • Operational savings Cost savings between IPv4/IPv6 operations • Cost avoidance time • Future wins11 © Copyright 2012 Hewlett-Packard Development Company, L.P.

  • 12. Transition Strategy Remote offices and branches WAN Three main categories Dual Stack • Provides complete support for IPv4 and IPv6 protocols Wireless LAN Core / DC Tunneling • Encapsulates IPv6 packets in IPv4 headers (and in later Campus LAN IPv4 packets in IPv6 headers) • Requires dual-stack devices at either end of the connection Translation IPv6 IPv4 Internet • Translates IPv6 addresses and into IPv4 addresses Internet Current State Disconnected from IPv6 Internet12 © Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
  • 13. Dual Stack Transition StrategySimple and widely used and recommended strategyUse IPv4 or IPv6• IPv4 and IPv6 protocol stacks implemented on the same device• + Most simple and recommended approach, network is the same; applications can select which network protocol to be used• – IPv4-only cannot communicate with IPv6-only, need to maintain 2 routing tables, need to maintain 2 firewall rule sets, requires additional memory and power, … IPv4 InternetApplication IPv6 Application Internet * IPv4 and IPv6 Networks can share a single link * IPv4 and IPv6 can be enabled on the same router13 © Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
  • 14. IPv6 TunnelingSimple and widely usedOne transport protocol is encapsulated as the payload of the other(6-in-4 or 4-in-6)• + Connect Islands of IPv6 or IPv4 (compatible nodes across incompatible networks) recommended for site-to-site• – Security issues with tunneled protocols through FW (FW can’t inspect payload) reduced performance, complicated network management + troubleshooting• Can be manual or automatic IPv4 IPv4 IPv4 IPv4 Application Router Router Application IPv4 Internet Tunnel IPv6 Tunnel Tunnel Function Function IPv6 IPv6 Application Application14 © Copyright 2012 Hewlett-Packard Development Company, L.P.

  • 15. IPv6 TranslationIf you must!Between IPv4 and IPv6 (NAT64/DNS64)• Translates IPv6 names & addresses into IPv4 names & addresses (and vice versa)• + Enables IPv6-only host to communicate with IPv4-only hosts (and vice versa); no modification to IPv4 or IPv6 end nodes, only at boundary routers• – Application incompatibilities (e.g. VoIP), need for ALG, and has all NAT drawbacks; increased complexity in network topology, Reduced Performance (dep. on HW), complicated troubleshooting NAT/ALG Gateway IPv4 IPv6 Application Internet IPv6 Application15 © Copyright 2012 Hewlett-Packard Development Company, L.P.
