Rain: RDMA-assisted In-Network Scheduling for Microsecond-scale Workloads

Collection of recent systems and networking research: Rain proposes an RDMA-assisted, programmable-switch in-network scheduler that buffers tasks and worker tokens on-switch and uses one-sided WRITE multicasts to pre-write large tasks, improving throughput and tail latency for microsecond-scale workloads (1.75x vs SOTA on RocksDB). Papers include a combinatorial MAB approach for multi-AP IEEE P802.11bq throughput tuning, AUGUSTE — an online-learning MAC scheduler that predicts uplink arrivals to deliver URLLC-like latency with far lower overhead in 5G testbeds, and BBR-Copilot — a QUIC-sideaux
