© 2014 IBM Corporation 3 Scope of this presentation  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. IPv6- challenges of a global enterprise 3 i.e.

© 2014 IBM Corporation 5 Statistics – How is it spread around the world?  Level of IPv6 readiness around 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 - IPv6- challenges of a global enterprise s/ 5

© 2014 IBM Corporation 8 Kicking it out of slow motion!  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 person plus 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 IPv6- challenges of a global enterprise 8

© 2014 IBM Corporation 9 How can people help?  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 IPv6- challenges of a global enterprise 9

© 2014 IBM Corporation11 Readiness assessment - continued  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 IPv6- challenges of a global enterprise 11

© 2014 IBM Corporation12 Readiness assessment - continued  Finally, roadmap & recommendations –Design & plan - prioritize Describe in a few paragraphs for each technology area what the transitional and target state would look like –Addressing plan, global routing, governance structure –Test & pilot Certify hard-/ software, create templates, update standards –Respond to initial business impact Deploy transitional solutions where required –Deploy target state architecture IPv6- challenges of a global enterprise 12

© 2014 IBM Corporation13 Building a global Address plan  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 IPv6- challenges of a global enterprise 13

© 2014 IBM Corporation14 Address plan - continued  Develop a hierarchy scheme – aggregation is important! –Could be Global – Geo – Country – Site - (Building) –Consider your multi-homing requirements / topologies and 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 IPv6- challenges of a global enterprise 14

© 2014 IBM Corporation15 Factors contributing to success  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) IPv6- challenges of a global enterprise 15
