2. Motivation • Increasing demand from industry and research • Bridge the gap between long-term research and large-scale experimentation • Fundamental need for large-scale testing and experimentation facilities • Beyond individual project testbeds • Including interoperability issues at all levels • Need for an interdisciplinary approach • Large systems perspective • Across layers • Socio-economic impact Test Platform for Future Internet Research?, Helsinki, 28 February 2008

3. Characteristics • Open federation as a design principle • Sustainable research infrastructure • User experience • Societal and economic impact • Dynamicity and openness Test Platform for Future Internet Research?, Helsinki, 28 February 2008

4. Principles • Dynamism • Develop the tools that help a testing customer to express the testing needs and get feedback on where, how and when testing can take place • Support discovery and composition of the requested testing environment configurations • Support the dynamic set-up of the needed interconnections and the provisioning of the requested environment, across administrative domains • Openness • Address the need for large-scale testing facilities in the area of communications by implementing an infrastructure for federating testbeds • Any testbed should be able to connect to the federation by implementing the necessary functionality at the border and by subscribing to the federation framework Test Platform for Future Internet Research?, Helsinki, 28 February 2008

5. Approach • Create a large scale testing and experimentation facility by integrating existing and emerging testbeds • Achieve scale and maintain independence through federation • that enables end-to-end interoperability testing of platforms, networks and services • that helps reducing the risks and costs of large-scale network infrastructure testing Test Platform for Future Internet Research?, Helsinki, 28 February 2008

6. Federation requirements • Openness Federation implies openness at all levels, including provision, implementation and use. • Excellence The federation principle aims for “best of breed” and must assure excellence of the capabilities of the federation from various aspects. • Management Managing federated testbeds is complex, but necessary for achieving scale, diversity, cost-efficiency and, last but not least, to improve the sustainability and quality of the individual testbeds and the federation as a whole. • Governance Interconnecting different testbeds belonging to different administrative domains means granting access to remote resources that are owned by different stakeholders.

7. Operational Coordination of the activities by a central entity Standard procedures for handling supply and demand of testing facilities Brokerage service for testing facilities and resources Effective procedures for protecting confidential information Transparent classification and rating of testing sites via standardised metrics Incentives for competition between test sites Transparent pricing Legal Terms & conditions for membership and/or subscription Handling of intellectual property rights Legal procedures for confidentiality issues Process for conflict resolution Legal procedures in case of abuse of rights or neglect of contractual obligations Federation framework Test Platform for Future Internet Research?, Helsinki, 28 February 2008

8. Legal Framework • Panlab as legal entity • Enabling formaly federated testing • Ensuring sustainability of Panlab concept • With participation of mayor stakeholders • Panlab legal structure • Preferably a non-profit organisation (optional PPP) • Governed by rules (e.g. Articles of Association) adopted by Panlab founders Test Platform for Future Internet Research?, Helsinki, 28 February 2008

9. Panlab Organisation • General Assembly • Panlab founders and further members (to join within Panlab membership model) • The highest decision making body • Executive structure • Executive Director and Panlab Office • Operation issues, such as coordinating tests/test projects, ensuring operational and administrative interfaces etc. • Technical and business development of the Pan-European Laboratory • Marketing and public relations Test Platform for Future Internet Research?, Helsinki, 28 February 2008

10. Federation framework • Technical • Testing process definition • Establishing a catalogue of components • Specification of testbed lifecycle • Testbed search engine Teagle • Secure remote access to testbeds • Scheduling of testing resources • Procedures for analysis and diagnostics • Performance monitoring • Troubleshooting and fault management Test Platform for Future Internet Research?, Helsinki, 28 February 2008

14. Testbed federation architecture • Objectives • Creating a federation by interconnecting testbeds of diverse technology in a single communication platform, and • Offering federation to the users following a single, harmonized methodology • Future-proof benefits • Network-technology independence; new network technologies would be incorporated in, or excluded from the platform, seamlessly, without architectural modifications. • Steady user experience; independent from the supported services, some of which may decay or new ones may be added as the landscape of networks technology changes over time, posing new testing requirements Test Platform for Future Internet Research?, Helsinki, 28 February 2008

16. IMS as a federation tool • Function blocks on top of the core control framework • User related functions: Preferences, Presence, and Directories … • Service operator functions (testing services): Charging, Session management, Identity, and Service Authorisation … • Network Management functions: Access control, Localisation, Authentication, and Authorisation … • The overall process to instantiate a testing configuration requires tools on the application layer to define, search, select, configure and control testbed components. It is a multi-step process starting with an interactive user session to describe the testing requirements, search by the system for available and capable network resources, and finally provision of relevant access tools to the users.

17. Provision of a testing environment • Components at the application level realised as specialised application servers • Testing Service Description providing knowledge and information about the testing service primitives available and how to utilize them. The testing service description server is providing information on demand and according to real resources’ availability • Testing Resources Search Engine asa specific application to match required testing resources against available assets from a global testbed database • Network topology management providing the knowledge related to network resources and topologies Test Platform for Future Internet Research?, Helsinki, 28 February 2008
