The International Conference on Transparent Optical Networks (ICTON) 2023, took place from 2 to 6 July at the Central Library of University Politehnica Bucharest, Romania. The theme of this year’s Conference was focused on the applications of transparent and all-optical technologies in telecommunications, computing and novel applications. 

Conference topics included, among others, digital all-optical networks, next generation networking,  network reliability and availability, wireless and optical networking, and 5G to 6G communications. All subjects discussed during the Conference are of great interest for the development of PREDICT-6G, which participated in ICTON 2023 with three sessions that have subsequently resulted in the publication of conference papers. 

On July 3, Dr. Luis Velasco and Marc Ruiz, members of the PREDICT-6G consortium on behalf  of the Universitat Politècnica de Catalunya (UPC), chaired the “8th Workshop on Beyond-5G Network Operation (B5GNeO)”. During the workshop, Jaume Comellas and Davide Careglio, also members of the UPC, presented two papers.


Jaume Comellas presented the paper “PILOT: A methodology for modeling the performance of packet connections”. This paper presents the PILOT methodology for modeling the performance of packet connections during commissioning testing in terms of throughput, delay and jitter. PILOT runs in a sandbox domain and constructs a scenario where an efficient traffic flow simulation environment, based on the CURSA-SQ model, is used to generate large amounts of data for Machine Learning model training and validation. The simulation scenario is tuned using real measurements of the connection obtained from a set of active probes.  You can read the full paper here.

Davide Careglio presented the paper “Disaggregated delay modeling in multidomain networks”. In this paper, the team proposes a collaborative environment, where each domain models intra-domain delay components of inter-domain paths and shares those models with a broker system providing the E2E connectivity services. The broker, in turn, models the delay of inter-domain links based on E2E monitoring and the received intra-domain models. You can read the full paper here.

The following day, July 4, also as part of the B5GNeO workshop invited presentations, Marc Ruiz from the UPC presented the paper “CURSA-SQ models for time-sensitive networking”. This paper focuses on analysing the impact of conveying time-sensitive traffic in operators’ networks when such traffic is mixed with best-effort traffic. In particular, extensions to a continuous G/G/1/k queue model are proposed to evaluate two different Ethernet technologies, synchronous and asynchronous, supporting time-sensitive flows in terms of their influence on the performance of best-effort traffic.
