    Abstract: A method and apparatus of a device that determines a cause and effect of congestion in this device is described. In an exemplary embodiment, the device measures a queue group occupancy of a queue group for a port in the device, where the queue group stores a plurality of packets to be communicated through that port. In addition, the device determines if the measurement indicates a potential congestion of the queue group, where the congestion prevents a packet from being communicated within a time period. If potential congestion exists on that queue group, the device further gathers information regarding packets to be transmitted through that port. For example, the device can gather statistics packets that are stored in the queue group and/or new enqueue packets.

    Abstract: A method for managing a network includes obtaining network flow data corresponding to a network device in the network, determining, based on the network flow data, configuration coverage associated with forwarding control configuration of the network device, identifying, using the configuration coverage and the forwarding control configuration, non-coverage, generating a plurality of synthetic packets based on the non-coverage, transmitting the plurality of synthetic packets to the network device, obtaining a set of results associated with the plurality of synthetic packets, making a determination, based on the set of results, that the network device is not implementing at least a portion of the non-coverage correctly, and based on the determination, performing a remediation action on the network device.

    Abstract: A method and system for maintaining persistent network policies for a virtual machine (VM) that includes determining a name of the VM executing on a first host connected to a first network device; binding the name of the VM to a network policy for the VM on the first network device; acquiring from VM management software, using the name of the VM, a universally unique identifier (UUID) of the VM; associating the UUID to the network policy on the first network device; applying the network policy for the VM on the first network device; subscribing to receive notifications from the VM management software of changes to the configuration of the VM corresponding to the UUID; receiving notification from the VM management software of a configuration change made to the VM corresponding to the UUID; and updating the network policy of the VM to reflect the configuration change of the VM.

    Abstract: A method for processing state information updates. The method includes receiving, by a coordination point, a plurality of state information from a plurality of network elements; processing at least one of the plurality of state information to generate a result; and applying the result to at least one of the plurality of network elements in order to modify an operation of the at least one of the plurality of network elements.

    Abstract: A method for managing networking devices. The method includes receiving, by a second management system, first network device state information (NDSI) for a first plurality of network devices, where the first NDSI is obtained by a first management system and where the first management system manages the first plurality of network devices. The method further includes initiating performance of a management action based on a result, wherein the result is obtained by processing at least the first NDSI.

    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.
