On 19–20 July 2025, the DESIRE6G project took part in the IETF 123 Hackathon in Madrid, an event bringing together experts and developers to collaborate on advancing Deterministic Networking (DetNet). Organized by the Internet Engineering Task Force (IETF), the hackathon fostered technical exchange, rapid prototyping, and real-time testing of new ideas.

As part of the hackathon, DESIRE6G led Challenge 2: In-band Telemetry (INT) for DetNet. This challenge focused on exploring how in-band telemetry can be used to monitor the performance of deterministic networks in real time. The team developed a Wireshark dissector enabling direct analysis from the data plane, providing valuable insights into network behavior and performance.

The challenge was led by Marta Blanco Caamaño (TID). David Rico Menéndez (UC3M), Cunwang Guo (TID), Luis Miguel Contreras Murillo (TID), and Carlos J. Bernardos (UC3M) played a key role in organizing the session and coordinating Challenge 1: Control Plane API and Intelligence.

“We showcased the potential of applying AI to accelerate and simplify the development of Wireshark dissectors for emerging protocols.” – Marta Blanco Caamaño

Many thanks to all participants who joined the session and helped advance this important work in deterministic networking.
