11. Key to success for experimental facilitiesLessons learned from FOKUS / TU Berlin An experimental facilityneeds a clearscope and identification of thecustomer/users Functionalscope: networks, serviceplatform, specificapplicationdomain ? Time scope: longterm (clean slate) vs. medium term (evolutionary) approaches ? User/customerscope: support of academiaorindustryorboth? Different approachesforproviding a testbed: Toolkitsforinhousetestbeds vs. jointinfrastructureoffering vs. federatedtestbeds Example: Open Source IMS Core vs. open IMS playground vs. PII Importance of technologybackwardcompatibility, standardscompliance and linkagetocommercial open developerplatforms Example Open IMS Core and OpenEPCas 3GPP referenceimplentations Example: FOKUS OSTP vs Open Developer Garden Portal of DTAG Lessonlearned: The closerexperimentationgetstothemarket (shiftfrom "R" to "D") themorechallengingistheuss of an open platform ( IPR Protection!)

12. Key to success for experimental facilitiesLessons learned from FOKUS / TU Berlin Provision of an Open Source Tools for testbed setup and federation PII Teagle Tool Example: Teagle and packet tracking tools for FIRE and national facilities Teagle is planned to be used for ETSI IMS/EPC Plugtests in 2011 How to stimulate testbed adoption Create awareness via tutorials, webinars, workshops and „showrooms“ Example: See FOKUS IMS Workshop series and new FUSECO Forum Open Testbed Challenges: Legal Issues – how to provide infrastructure access to third parties? Payment issues - who pays for the provided testbed infrastructures Company security policies (testbeds run in front of the firewall!) Constrain resource sharing
