  1. Andy Mindnich – Global IPv6 Architect, IBM Office of the CIO IPv6-Kongress, Frankfurt/Main - May 22nd 2014 Introducing IPv6 - Challenges of a global enterprise

  2. Agenda IPv6- challenges of a global enterprise • Statistics – IPv6 growth and spread around the world • Inhibitors for progress • Looking back • Kicking it out of slow motion! • How can people can help? • Example of a Network Readiness Assessment • Building a global address plan • Factors contributing to success

  3. Scope of this presentation IPv6- challenges of a global enterprise • This presentation solely focuses on IBM internal infrastructure and services • The intention is to show some typical challenges of a global enterprise, wanting to roll-out IPv6 for its own users, such as IBM • There is a wealth of other teams and areas in IBM working on IPv6: • Product development & testing, Customer & Shared infrastructures, Network & Consulting services, RedBooks, Cloud infrastructure, etc. i.e. http://www-01.ibm.com/software/info/ipv6/compliance.html 3

  4. Statistics – How is IPv6 growing? http://www.google.com/ipv6 3,6% Doubling every 6 months http://www.akamai.com/ipv6 IPv6- challenges of a global enterprise • Growth rates are real,for content and users • More and more RIRs running out of IPv4 space • Device growth is fueling need for more addresses http://www.internetlivestats.com/ Cisco: Internet of Things 4

  5. Statistics – How is it spread around the world? IPv6- challenges of a global enterprise http://6lab.cisco.com/stats/ • Level of IPv6 readinessaround the globe differs • Several European countries leading • Future growth markets can start without a legacy environment • Use IPv6 to help facilitate Enterprise growth initiatives • i.e. IBM is expanding heavily into Africa, opened a Research lab, a client and innovation center, has a presence in 20 countries, and continues to expand → don't count on IPv4 to support the growth Source: IBM in Africa - https://www-03.ibm.com/press/us/en/presskit/34710.wss 5

  6. Inhibitors for progress IPv6- challenges of a global enterprise • We have large amounts of IPv4 addresses, not yet running out... • You told me already 10 years ago and the network is still running... • Other priorities, such as refresh programs, transformation programs... • IPv6 is not 'cool', such as mobile apps, BYOD, analytics... people don't understand the benefit • Seen as a network only project → No urgency to move 6

  7. Looking back IPv6- challenges of a global enterprise • 2005, acquired first IPv6 prefix from ARIN • Established a preliminary address plan and high-level migration plan • Submitted network investments every year – but got little funding • Lab & island deployments, mainly for product testing & research • 2011, IBM Academy of Technology study (corporate technology board) • 2012, kicked of Network readiness assessment • 2013, finished Network readiness assessment 7

  8. Kicking it out of slow motion! IPv6- challenges of a global enterprise • 2013 • conducted many briefings with executive team (up to CIO), educating them about current state and importance • Projected an Enterprise Program office in the long run, but proposed to start with staffing at least one dedicated personplus an executive sponsor • 2014 • Announced a global CIO IPv6 architect (see next page) • Received funding to start proof-of-concept and pilot work • Create a global address plan • Prepare IPAM (IP Address Mgmt) tools to start allocating IPv6 ranges • Start assessing other technology towers 8

  9. How can people help? IPv6- challenges of a global enterprise • Nominated a global CIO IPv6 architect / evangelist • Articulate detailed IPv6 strategy, based on Business(!) and IT-Strategy • Engage with all technology towers to get awareness • Develop business briefing material to spread the message • Establish linkages into • ARC (Architecture Review Council) reviews • Strategy papers • Investment plans & Business planning • Enlist buy-in from every technology tower to embrace IPv6 • Make it a 'tick in the box' item for any review – business or technical • Announced an executive sponsor for IPv6 in the management team 9

  10. What can a Network Readiness assessment look like? IPv6- challenges of a global enterprise • Good advice: Get help from someone who has done that before! • Current state discovery • Describe overall global architecture, as well as Geo specifics • List inventory and assets • IPv6 readiness analysis • List Software and Hardware readiness • Solution alternative analysis • Use case scenarios • Global routing alternatives • Addressing alternatives Data i.e. from 'Cisco IPv6 Solutions' 10

  11. Readiness assessment - continued IPv6- challenges of a global enterprise • Technical areas (each one itself split by Geo) • Wide Area Network • DNS, DHCP and IP Address Management (ext. & int.) • Security Perimeter • External Web Presence, Remote User Access, Outbound Internet, External Electronic Mail, Relevant Global Security Standards • Local Area Network • Global LAN Standards • Global WLAN Standards • Business Partner connectivity • Voice & Video • Management and operation tools • Lab and testing environment 11

  12. Readiness assessment - continued IPv6- challenges of a global enterprise • Finally, roadmap & recommendations • Design & plan - prioritizeDescribe in a few paragraphs for each technology area what the transitional and target state would look like • Addressing plan, global routing, governance structure • Test & pilotCertify hard-/ software, create templates, update standards • Respond to initial business impactDeploy transitional solutions where required • Deploy target state architecture 12

  13. Building a global Address plan IPv6- challenges of a global enterprise • Talked to other enterprises & service providers • Acquired new single /32 IPv6 prefix (PI space) from ARIN • Why a new one? Three options: • Single PA prefix • Single PI prefix • Multiple PI prefixes from each RIR Need to weigh the risks – there is no guarantee for the future 13

  14. Address plan - continued IPv6- challenges of a global enterprise • Develop a hierarchy scheme – aggregation is important! • Could be Global – Geo – Country – Site - (Building) • Consider your multi-homing requirements / topologiesand the levels of aggregation • Consider the opportunity to include a functional code into the addressing (i.e. Infrastructure, Desktop/WLAN, Guest, Voice, ... ) • All sizes equal, or conservative? • Keep in mind a /48 as minimum routable prefix externally 14

  15. Factors contributing to success IPv6- challenges of a global enterprise • Global standardization: test once, roll-out thousands of times • Centralized IPAM & IP registrar function • Evolution of services (i.e. new WAN offerings) • Lifecycle & refresh programs • Leverage other corporate initiatives such as Mobile, BYOD, Internet of Things, etc. • Think about using controller based WLAN as an overlay • Acquisitions that come IPv6 ready (example: Softlayer) 15
