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

3
Characteristics
  • Open federation as a design principle
  • Sustainable research infrastructure
  • User experience
  • Societal and economic impact
  • Dynamicity and openness

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

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

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
Federation framework
  • 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

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

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

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

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

15
Common layered architecture
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 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
