This paper describes the pathway towards the realisation of a 5G Facility that will allow the validation of the major 5G Key Performance Indicators (KPIs). It reflects the approach that the 5GENESIS consortium will adopt in this direction. More precisely, it describes the key design principles of such Facility as well as the targeted use cases for the KPIs validation. The adopted approach for the Facility realisation includes the design of a common implementation blueprint that will be instantiated in five Platforms distributed across Europe. To maximise the diversity and the efficiency of the Facility, complementary performance objectives have been selected for the Platforms, while specific characteristics from different vertical industries have been allocated to each of them.
Abstract. The flat architecture adopted in LTE increases the scalability of the network in order to accommodate large volumes of user traffic, reduces packet latency and the cost per byte. At the same time the enhanced Node B (eNB) has increased its complexity which have implied the appearance of new challenges in the field of experimental performance tests [1]. To cope with these challenges, access to a real and controlled experimentation environment is needed. Nevertheless, the high cost of laboratory equipment makes it difficult to carry out realistic experiments for most research teams, whose work usually rely on simulations. A combination of highly configurable equipment and software tools accessed remotely seems to be the best solution to improve research activities around LTE technologies and beyond. PerformLTE testbed provides a controlled environment where LTE end-to-end IP communication, including radio impairments and network perturbations, and complex network setups can be reproduced.
This paper presents the design options for creating a Pan-European mobile network for research in the context of the European Horizon 2020 EuWireless project. The most likely direction is a platform that makes it easier to create network slices for research. In this context, we identify one promising technology to implement network slicing in 5G networks: the framework GÉANT Testbeds Service (GTS). GTS is currently a production service by GÉANT that offers remote construction and use of virtual testbeds for wired networks mapped to the real GÉANT infrastructure. These GTS-virtualized testbed environments conform to Software Define Networks (SDNs) principles and offer compute, storage, and switching resources, at scale and with line rate performance. In this paper, we explain how the current (wired oriented) GTS can be extended with the 5G components, such as radio access nodes (gNBs), transport networks, user devices, etc., in order to implement 5G network slices. Our first conclusion is that using GTS for EuWireless implementation is feasible, dramatically increasing the potential impact of this service in the research community.
