  • MICROBURST DETECTION AND MANAGEMENT
    Publication number: 20220038374
    Abstract: Systems, methods, and apparatuses provide a scalable framework for analyzing queuing and transient congestion in network switches. The system reports which flows contributed to the queue buildup and enables direct per-packet action in the data plane to prevent transient congestion. The system may be configured to analyze queuing in legacy network switches.

  • Systems and methods for optimized route caching
    Patent number: 10700975
    Abstract: A method for optimized route caching includes comparing a destination address of a network packet to a first set of prefixes in a routing cache, and comparing the destination address to a second set of prefixes in a full routing table when a longest matching prefix for the destination address is not found in the routing cache. The method further includes copying the longest matching prefix and a set of sub-prefixes of the longest matching prefix from the full routing table to the routing cache, and forwarding the network packet.
