The 25th International Conference on Transparent Optical Networks (ICTON 2025) was held from 6 to 10 July 2025 in Barcelona, Spain. The scope of the Conference and co-located events focused on the applications of transparent and all-optical technologies in telecommunications, computing, sensing, and novel fields. The Universitat Politècnica de Catalunya (UPC), a member of the PREDICT-6G consortium, organised the ICTON 2025 conference.
PREDICT-6G presented three papers. Written by researchers from the UPC, Nextworks, Eviden and the Universidad Carlos III de Madrid (UC3M), the paper titled “Demonstration of a Control Plane in Support of E2E Deterministic Service Provisioning over a Multi- domain Multi-technology 6G Network” presents the operation of a multi-domain multi-technology control plane architecture designed to provision end-to-end (E2E) connectivity with deterministic performance guarantees. Key innovations highlighted in the demonstration include homogenised configuration of diverse data plane technologies, advanced topology abstraction enabling Key Performance Indicator (KPI)-aware path computation, and the use of digital twin (DT)-based KPI estimation to support deterministic connectivity configuration. These capabilities collectively showcase a promising approach for managing the complexity and performance demands of future 6G networks. You can read this paper on Zenodo here.
“On the selection of KPI-aware E2E paths for deterministic services in 6G networks”, written by researchers from the UPC and Telefónica Research and Development, describes how, in the 6G ecosystem, the provisioning of deterministic services with KPI guarantees over multi-technological network domains requires the proper selection of the E2E paths. The paper discusses the challenges of the E2E path/domain selection, provides an overall supporting control plane architecture and presents a proof of concept. You can read this paper on Zenodo here.
“Bridging the gap between TSN and Open-Source”, written by researchers from the UC3M and the Universidad de Málaga (UMA), presents a fully open-source TSN-enabled programmable software switch and Detnet router platform built atop eXpress Data Path (XDP) and Extended Berkeley Packet Filter (eBPF) in the Linux kernel. Our platform integrates IEEE 802.1Qbv time-aware shaping, IEEE 802.1Qcr Asynchronous Traffic Shaping, IEEE 802.1AS-based Precision Time Protocol (PTP) time synchronization, as well as DetNet functionalities including packet replication, elimination and or dering functions (PREOF). You can read this paper and its presentation on Zenodo here and here.
