  • Method and system for detecting abnormalities in network element operation
    Patent number: 10999131
    Abstract: A method for detecting abnormalities in network element operation. The method includes monitoring at least a portion of the network element for abnormalities and making a determination that an abnormality exists, in response to the monitoring, and based on the determination, tracking the abnormality. An abnormality includes a measured performance that deviates from a nominal performance, but that does not cause erroneous behavior of the network element.
    Type: Grant
    Filed: September 19, 2019
    Date of Patent: May 4, 2021
    Assignee: Arista Networks, Inc.
    Inventors: Robert E. Gilligan, Kenneth James Duda

  • Bidirectional forwarding detection accelerator
    Patent number: 10530869
    Abstract: A network device for performing bidirectional forwarding detection (BFD) includes a processor that receives packets from a peer; a session state machine that manages a session with the peer; a receive module that determines whether the packet indicates no change to the session; and a transmit module. The transmit module transmits BFD packets at an interval determined by the session state machine and transmits a session change packet in response to a configuration update by the session state machine.
