Latest Patents

Xian Wu holds a patent for a system titled "Admission control for latency-critical remote procedure calls in datacenters." This patent describes a distributed sender-driven Admission Control System (ACS) that leverages Weighted-Fair Quality of Service (QoS) queues. The system guarantees RPC level latency service level objectives (SLOs) by judiciously selecting QoS weights and managing traffic mix across QoS queues. The ACS installs cluster-wide RPC latency SLOs by mapping latency-sensitive RPCs to higher weight QoS queues. It also adapts to overloads by apportioning latency-sensitive RPCs among QoS queues based on measured completion times. When network demand spikes unexpectedly, the ACS achieves a latency SLO significantly lower than state-of-the-art congestion control at the 99.9th percentile and admits more RPCs meeting SLO targets.
