UCLouvain researchers at IETF126
Three researchers from the lab attended IETF126 in Vienna, Austria. Louis Navarre championned a Hackathon on a minimal implementation of Multicast QUIC. They were able to live stream Louis’s Macbook webcam to 4 other devices (2 laptops and 2 phones) using their minimal Multicast QUIC implementation. They modified three implementations: quiche, aioquic & quinn. Additionally, Anthony Doeraene presented his paper on extending PIM to expose network capabilities for modern multicast at the ANRW 2026.
UCLouvain researchers at IETF118
Four researchers from UCLouvain will attend IETF118 in Prague. IETF meetings are important for researchers who develop or enhance Internet protocols because they encourage interactions with engineers who deploy these protocols at a large scale. At IETF118, UCLouvain contributions will focus on QUIC, TCP, TLS and BGP.
Flexible QUIC loss recovery mechanisms for latency-sensitive applications
Transport protocols such as TCP cope with packet losses by using acknowledgments and retransmissions. This technique is also used by recent protocols such as QUIC. Using retransmissions is the best approach to cope with packet losses from a bandwidth viewpoint, but they cause increases in delays and can affect latency sensitive applications.
