2 Improved Agility and reduced costs by managing the T- WLAN HotSpots with HP Network Automation Peter Kölbel, Deutsche Telekom

3 Group profile and figures. Company Products Facts and Figures Employees Global Group Deutsche Telekom is one of the world s leading service companies in the telecommunications industry Our strengths Products and services for the fixed network, mobile communications, the Internet and IPTV for consumers, and ICT solutions for business customers and corporate customers. By the numbers In 2010, Deutsche Telekom reported revenue of EUR 62.4 billion (more than half was generated outside of Germany). Adjusted EBITDA totaled EUR 19.5 billion and free cash flow EUR 6.5 billion. Major factor in success: At march 31, 2011, the total headcount stood at about 244,000. 3

4 Business Case: Telekom HotSpots Textbox Requirements Headline High availability Security Keep pace with changes Time to market Textbox Infrastructure Headline HotSpots at hotels, coffee shops, airports, trains and trainstations etc. Telekom Backbone Infrastructure network devices Cisco Routers Qualcom Flarion Routers Funkwerk (Access Points) RAD Juniper Simple, fast and secure management of IP networking infrastructure

5 Situation Before Automation Textbox Challenges Headline Ressource intensive configuration manual configuration (e.g.15 min per access list configuration) Rollback of Changes with very high manual effort Scalability through hardware extensions Error-prone changes (sometimes no success) No Snapshots (e.g. passwords encoded, network configuration) unsufficient documentation Different vendor specific tools require different skills Several maintenance contracts Goal: Improve processes, optimize resources and costs

6 Goal: Better Agility, Availability, Security Textbox Improve Headline processes, optimize resources and costs Improve processes from manual to automated configuration reduce downtime and time-to-market always up-to-date configuration automatic synchronization between inventory database and live network Optimize ressources and costs standardize reduce maintenance fee reduce hardware costs reduce manual workload for ressources Invest into the future

8 Network Automation in Production Example: Difference report

9 Improvements Improvements Without Automation With Automation Infrastructure and resources 1500 networking devices Several Servers / different tools several maintenance contracts several people approx networking devices 2 Servers / high availability / 1 Tool one maintenance contract one person managing all devices Configuration Access list configuration: weeks Manual error-prone changes IOS updates: weeks big effort for rollback if change failed access list configuration: 5-10 minutes for preparation then fully automated reconfig appr automated changes / month IOS updates: hours automated rollback Compliance unsufficient documentation continuous documentation automated security and configuration compliance checks, automated reconfiguration according to policy

10 Challenges during HP NAS implementation Textbox Headline New driver needed for unsupported network devices (solved) System went down when using many pearl scripts in parallel (solved) Java-Problems (solved by setup config change) Swap Space issue (solved by setup config change) Performance problems with Orale DB (Oracle issue solved) Drivers not visible ( fixed in HP Network Automation 7.5) Issues with Tasks Root Cause in Solaris

11 Current Overview of the HP NAS implementation at Deutsche Telekom and next Steps Textbox Headline Overview Licences System is beeing used across different departments Changes are made on components in 13 services Many changes are done automatically via scheduler Next Steps Expand the system where possible and useful Move to Linux Splitt the Application and the Database to different devices

13 Network Automation Project Textbox Requirements Headline and Solution Standardized tool which supports different networking devices Solution: HP Network Automation Decision process: Use of internal reference (T- Mobile USA) managing networking devices Textbox Implementation Headline Start with small project 1500 Access points for Railnet Driver Support for Funkwerk devices (ARTEM) needed Second Step: Project enhancement for mobile hotspots and T-Mobile Backbone exchange license to grow from 1500 to > devices Database exchange (from SQL Server to Oracle)
