IPv 6 - challenges of a global enterprise 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 IPv 6 for its own users, such as IBM There is a wealth of other teams and areas in IBM working on IPv 6: – Product development & testing, Customer & Shared infrastructures, Network & Consulting services, Red. Books, Cloud infrastructure, etc. i. e. http: //www-01. ibm. com/software/info/ipv 6/compliance. html 3 3 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise Statistics – How is IPv 6 growing? Growth rates are real, for content and users http: //www. google. com/ip v 6 3, 6% Doubling every 6 months More and more RIRs running out of IPv 4 space Device growth is fueling need for more addresses Cisco: Internet of Things 4 4 http: //www. akamai. com/ipv 6 http: //www. internetlivestats. com/i nternet-users/ © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise Statistics – How is it spread around the world? http: //6 lab. cisco. com/stat s/ Level of IPv 6 readiness around the globe differs Several European countries leading Future growth markets can start without a legacy environment Use IPv 6 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 IPv 4 to support the growth Source: IBM in Africa - https: //www-03. ibm. com/press/us/en/presskit/34710. wss 5 5 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise Inhibitors for progress We have large amounts of IPv 4 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. . . IPv 6 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 6 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise Looking back 2005, acquired first IPv 6 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 7 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise 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 IPv 6 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 IPv 6 ranges – Start assessing other technology towers 8 8 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise How can people help? Nominated a global CIO IPv 6 architect / evangelist – Articulate detailed IPv 6 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 IPv 6 – Make it a 'tick in the box' item for any review – business or technical Announced an executive sponsor for IPv 6 in the management team 9 9 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise What can a Network Readiness assessment look like? 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 – IPv 6 readiness analysis • List Software and Hardware readiness 10 1 – Solution alternative analysis • Use case scenarios • Global routing alternatives • Addressing alternatives Data i. e. from 'Cisco IPv 6 Solutions' © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise 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 11 1 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise 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 12 1 – Deploy target state architecture © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise Building a global Address plan Talked to other enterprises & service providers Acquired new single /32 IPv 6 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 1 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise 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 14 1 © 2014 IBM Corporation

IPv 6 - challenges of a global enterprise 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 IPv 6 ready (example: Softlayer) 15 1 © 2014 IBM Corporation
