  • Prioritized restoration of connections and sessions
    Patent number: 11917017
    Abstract: Systems and methods are provided for prioritized restoration of multiple network connections that have been interrupted. Connection state data (e.g., quantity of pending IO requests) may be used to prioritize reestablishment of some connections over others. In addition, the connections may be reestablished using “in-band” handshakes over the previously-established network connections.

  • Tunable-granularity multi-level histograms for efficient computer system metric analysis
    Patent number: 11190419
    Abstract: Memory is identified for a first set of histogram buckets for a metric with bucket value ranges distributed according to a first function, and a second set of histogram buckets with bucket value ranges distributed according to a second function. The second set of buckets overlaps with a metric value range targeted for enhanced granularity analysis. After the histogram is updated in response to obtaining metric values, a representation of at least some of the buckets is sent to a destination.

  • Adaptive recovery based on incast
    Patent number: 10581715
    Abstract: Systems and methods for an incast mitigation approach that first modifies network responses for content requests above a threshold size to be delayed according a response latency selected from an established latency range. Additionally, as incast characteristics are analyzed from network traffic, the volumes can selectively modify the individual established latency range to increase the latency range during periods of higher incast characteristics and to decrease the latency range when incast characteristics appear to be decreasing.
