D4.3. Improved Testbed Configuration

A testbed provides the necessary infrastructure to perform any of the following tasks: (a) run the use cases, (b) operate the RECAP infrastructure, (c) run simulations, and (d) gather monitoring data. RECAP features three different testbeds that provide different capabilities to the project's use cases and that provide the necessary infrastructure for integration, benchmarks and validation.

All three testbeds address the main requirements defined earlier in the project by the different use cases: (i) support for virtualisation; (ii) a multi-location set-up to mimic the core and edge data centres; (iii) monitoring support for the infrastructure; (iv) power control over the testbed hardware.
The UULM testbed is a use case agnostic testbed. It provides a generic IaaS OpenStack interface together with monitoring support for the infrastructure. The testbed spans two physical locations. The first one with powerful server hardware and massive storage represents the cloud part of today's infrastructures. The other location with smaller and fewer hardware represents the edge location. The cloud-like location also provides power control for the hardware. The testbed provides sufficient resources to run the RECAP infrastructure as well as all use cases. In particular, it is suited for Use Case B 'Big Data Analytics Engine' and Use Case C 'Edge/Fog Computing for Smart Cities', and the major platform for running the RECAP simulator and storing the monitoring data for all use cases. It is open to any project partner and resources are provided on basis of needs.

The TIETO testbed is specifically tailored to Use Case A 'Network and Infrastructure Management' and D.2 'Cloud Connect Intelligence'. The testbed represents a subset of a telecommunication system and is used in a lab environment for telecom-oriented scenarios. It allows developing and optimizing solutions for end-to-end telecommunication infrastructure services in emerging 5G mobile networks, as well as better solutions for industry verticals dependent on the communication services. The testbed is used to evaluate the capabilities of a common physical infrastructure spanning over vertical regions of software-defined infrastructure. In particular, it emulates the characteristics of end-to-end communication and content services for different categories of horizontal content services (network slices) with different Quality-of-Service requirements.

BT runs a Research Platform data centre that is used to support its own and collaborative research projects. BT's Network Functions Virtualisation (NFV) research makes use of this facility. The BT NFV Lab has dedicated and shared resources in the Research Platform. These resources are specifically tailored to use cases D.1 and D.2, 'Virtual CDN' and 'Cloud Connect Intelligence' respectively. Resources in the testbed can be made available to consortium partners as needed.

The testbeds accompanied by this document are important to the project as they enable the operation of the use cases and the RECAP infrastructure. Moreover, they allow the collection of monitoring data and finally, the validation and improvement of the RECAP approach.
