Implementing Multicast with eBPF and Cilium

Learn how eBPF and Cilium enable efficient multicast networking in Kubernetes clusters through this technical conference talk. Explore the implementation of pod-to-pod multicast delivery, focusing on both high-level concepts and detailed technical aspects. Discover how multicast technology benefits industries like finance, telecommunications, and media CDNs by efficiently replicating and delivering data streams to multiple clients. Understand the challenges faced in traditional multicast infrastructure configuration and how Cilium's eBPF-based approach simplifies this complexity. Gain practical insights into multicast functionality, the advantages of using eBPF as an alternative to conventional multicast infrastructure, and the implementation of Cilium as a multicast-enabled Container Network Interface (CNI).
