Towards an Internet Deployment of Flexible Multicast QUIC

Despite their scalability benefits, multicast protocols are not widely deployed and are confined to intra-domain use cases such as IPTV. Several factors contribute to this reluctance to deploy multicast on the Internet. Among them, the chicken-and-egg and all-or-nothing problems hindered the emergence of inter-domain multicast. Recent advancements within the IETF suggest solutions to these issues, such as Automatic Multicast Tunneling (AMT) and flexible multicast extensions to the QUIC transport protocol (FCQUIC). This demo leverages AMT and Flexicast QUIC to enable researchers to conduct large-scale inter-domain multicast measurement campaigns. We provide Docker images of FCQUIC receivers that can be connected to our FCQUIC source, which any Internet host can reach using AMT. We will also publish our setup code to motivate researchers to instantiate their own FCQUIC source application with AMT.
