NTN. On top of the terrestrial dedicated dark fiber link between the two sites in Athens platform, a satellite/NTN-emulator is currently under deployment, which will enable multi-operator and multi- access scenarios, such as inter-Public Land Mobile Network (PLMN) hybrid-access and dual- connectivity, with agility and low cost. ATSSS enables efficient use of multiple RATs in a multi- connectivity scenario. The emulated satellite opens this field for further research into custom solutions where different PDU sessions per access can run in parallel. Specifically, the solution supported by the Athens platform involves the use of MPTCP to combine multiple network paths (i.e., the terrestrial and the emulated satellite/NTN) in a single TCP connection. The satellite emulated based approach of the Athens testbed can emulate a complete DVB-RCS2 – DVB-S2 system in a realistic and flexible way and its ability to interconnect with real equipment and applications provides excellent experimentation means. It is a distributed platform, which is composed of a satellite network on the operator side and Satellite Terminals (STs) at the client side. The satellite operator part is composed of a backbone network between satellite Gateways (GWs), capable of being interconnected to external networks, providing satellite network access on each terminal and gateway. The offered emulation platform allows the experimenter to emulate mesh and star configuration schemes as well as multi spot and multi gateway topologies. It provides configuration and monitoring (real-time and offline) tools to evaluate the performance of the emulated scenarios, supporting IPv4, IPv6 and Ethernet connectivity.
NTN. The current integration of the Starlink satellite connectivity allowed a very static use of the Satellite resources. To extend the usability of the Satellite connection services by experiments, an update of the VPN system that provides the isolated NTN links via Starlink is planned. In addition to this software- based enhancement, a secondary Antenna is planned to arrive soon.

Keysight tools All pertinent 6G test and measurement software tools provided by Keysight will be deployed on the Athens platform, with the explicit objective of boosting and augmenting the capabilities of the platform. These tools will be integrated seamlessly into the existing infrastructure, equipping the Athens platform with advanced functionalities for comprehensive testing and measurement within the context of 6G technology. This strategic deployment aims to enhance the platform's potential and enable efficient evaluation and optimization of 6G networks, thereby supporting the experimenters. OpenNebula OpenNebula will be installed in the Athens platform, serving as an additional infrastructure manager within the broader infrastructure of the 6G-SANDBOX facility. By leveraging Op...
