An experimental facility needs a clear scope and identification of the customer/users
– Functional scope: networks, service platform, specific application domain ?
– Time scope: long term (clean slate) vs. medium term (evolutionary) approaches ?
– User/customer scope: support of academia or industry or both?
Different approaches for providing a testbed:
– Toolkits for inhouse testbeds vs. joint infrastructure offering vs. federated testbeds
– Example: Open Source IMS Core vs. open IMS playground vs. PII
Importance of technology backward compatibility, standards compliance and linkage to
commercial open developer platforms
– Example Open IMS Core and OpenEPC as 3GPP reference implentations
– Example: FOKUS OSTP vs Open Developer Garden Portal of DTAG
Lesson learned: The closer experimentation gets to the market (shift from "R" to "D")
the more challenging is the uss of an open platform ( IPR Protection!)
– Example: Connecting to the FOKUS FUSECO Playground vs. OpenEPC Toolkit to
establish a private FUSECO Playground

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

Checklist for successful FIRE experimentation
General comment: Today we already have a number of good approaches and prototypes
but we have to align them and define a clear process on how to use them
(1) Select the best testbeds (criteria: scientific citations / industry usage)
(2) Agree on federation framework, specifically:
Control framework / provisioning interfaces
Identity Management (Ispec)
Policy description (Pspec)
Resource description (Rspec)
