SprayCast: Congestion-Adaptive Native Multicast for Dynamic Sparse All-to-All Communication
SprayCast is proposed, a congestion-adaptive native RDMA multicast scheme for dynamic sparse token Dispatch that uses in-band network telemetry feedback to steer replication away from congested multicast branches and range-based negative acknowledgments for localized loss recovery, saving bandwidth and reducing tail latency in dynamic all-to-all communication.
