  • Patent number: 11044197
    Abstract: In general, embodiments of the invention relate to processing network traffic data units (NTDUs). More specifically, embodiments of the invention relate to processing NTDUs transmitted between client device and the one or more protected resources. The protected resources are logically surrounded by a perimeter, which is implemented as a set of network devices that manage the flow of NTDUs between client devices and the protected resources. The perimeter works in conjunction with a set of filtering devices to determine whether a given NTDU can ultimately be transmitted to, and processed by, a protected resource.

  • 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.

  • Patent number: 10873882
    Abstract: A method and apparatus of a device that triggers a pause watchdog is described. In an exemplary embodiment, the device receives a pause message from a second network element on a first network element, where the pause message indicates that data should not be transmitted by the first network element. The device additionally triggers a pause watchdog on the first network element if the pause message is above a pause watchdog threshold, where the pause watchdog reduces the effect of the pause message.

  • Patent number: 10826773
    Abstract: Embodiments of the invention may relate to methods, systems, and/or non-transitory computer readable mediums for sidelining Such sidelining may include making a first determination, by a first network device, that a first network device state has degraded and making a first request, based on the first determination, to receive a first sideline token from a network controller. The network controller, in response to the first request, may make a second determination that a remaining sideline token is available. The method may also include receiving, by the first network device and based on the second determination, the remaining sideline token from the network controller and initiating, by the first network device, a graceful offlining based on receiving the remaining sideline token.
