Test Platform for Future Internet Research?, Helsinki, 28 February 2008 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


Characteristics Open federation as a design principle Sustainable research infrastructure User experience Societal and economic impact Dynamicity and openness


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


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


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.


Federation frameworkOperational

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


Legal Framework

Panlab as legal entityEnabling formaly federated testingEnsuring sustainability of Panlab conceptWith participation of mayor stakeholders

Panlab legal structurePreferably a non-profit organisation

(optional PPP)Governed by rules (e.g. Articles of

Association) adopted by Panlab founders


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


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

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

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.


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 as a 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
