Latest Patents

One of Gautam's latest patents is titled "Network congestion control in sub-round trip time." This invention provides congestion control mechanisms designed to reduce data transmission queues and enhance link utilization through precise congestion signals and the reduction of control loop delay. The congestion control system (CC) utilizes Back-To-Sender (BTS) packets over round trip time (RTT) control loop delay to react to congestion more swiftly. Additionally, the CC system applies Proactive Ramp-up (PRU) to identify flow completions, ensuring that released bandwidth is utilized promptly. Furthermore, the CC system employs supply matching (SM) through network calculus concepts to boost link utilization, ultimately reducing network latency and improving data flow completion times compared to other methods.

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