COMSYS @ ANRW 2025

In July, COMSYS researcher Ike Kunze attended the 2025 edition of the ACM/IRTF Applied Networking Research Workshop (ANRW), co-located with the IETF 123 meeting in Madrid, Spain. The workshop brought together researchers (from academia) and domain experts from major Internet companies, facilitating discussions on IETF-related topics and exchanges with corresponding IETF working groups.

In this fruitful environment, Ike presented his latest research on applying explicit flow measurements to network tomography, continuing his efforts on the spin bit and related concepts and further contributing to the advancement of novel network management approaches. Furthermore, Kathrin Elmenhorst, a former COMSYS student now at Osnabrück University, presented a collaborative paper on her Master’s thesis co-authored by Ike and fellow COMSYS researcher Constantin Sander. This work focuses on challenges for MASQUE caused by cascades of nested and unnecessary acknowledgments, contributing valuable insights to ongoing conversations in the MASQUE working group.

In addition to presenting at ANRW, Ike took the opportunity to participate in the IETF hackathon organized on the weekend before the main IETF meeting and in numerous working and research group sessions throughout the week. By engaging with different existing and upcoming initiatives, such as those concerning sustainability aspects of the Internet or preparing for energy-efficient networking, he continued COMSYS’s commitment to making the Internet better and more sustainable.
