Explore a novel architecture for efficient multicast in datacenter networks through this conference talk from NSDI '22. Dive into Orca, a system that addresses scalability challenges by dividing tasks between switches and servers, and partially offloading multicast session management to servers. Learn how this approach significantly reduces switch state, minimizes bandwidth overhead, and maintains constant processing overhead without limiting multicast session size. Examine the implementation results from both a testbed and large-scale simulation, comparing Orca's performance to state-of-the-art systems. Discover how Orca optimizes data transfer in multicast applications, potentially reducing communication time in datacenter environments.
