    Abstract: Methods and apparatus for automatically identifying and correcting faults relating to poor communications service in a wireless system, e.g., in real time, are described. The methods are well suited for use in a system with a variety of access points, e.g., wireless and/or wired access points, which can be used to obtain access to the Internet or another network. Access points (APs), which have been configured to monitor in accordance with received monitoring configuration information, e.g. on a per access point interface basis, captures messages, store captured messages, and in collaboration with network monitoring apparatus which can be in an AP or external thereto, use message sequences to determine a remedial action to be automatically taken when poor service is likely as may be predicted based on the detected message sequence between a UE and one or more APs.

    Abstract: An apparatus includes a virtual switch hosted at a first network device. The virtual switch is configured to receive a data packet from a first virtual resource hosted at the first network device to be sent to a second virtual resource hosted at a second network device. The virtual switch is configured to encapsulate the data packet to define an encapsulated data packet using a tunnel header, which has a first portion associated with the first and second network devices, and a second portion associated with a data flow between the first and second virtual resources when the data packet is sent from the first network device to the second network device. An Internet Protocol network can use the second portion of the tunnel header to load balance the data packet with respect to other data packets sent from the first network device to the second network device.

    Abstract: A controller device manages a plurality of network devices. The controller device includes one or more processing units configured to receive an indication of a stateful intent, the data structure including a plurality of nodes and a plurality of edges, each node of the plurality of nodes being representative of a respective network device of the plurality of network devices. The one or more processing units are configured to determine, using an abstract function configured at a node of the plurality of nodes, a stateless intent for implementing the stateful intent and generate low level configuration data for the plurality of network devices based on the stateless intent. The one or more processing units are configured to interface with one or more of the plurality of network devices to configure the one or more of the plurality of network devices with the low level configuration data.

    Abstract: Techniques are described for providing fast reroute for BUM traffic in EVPN. For example, a first provider edge (PE) device, elected as a designated forwarder (DF) of an Ethernet segment, configures a backup path using a label received from a second PE device of the Ethernet segment (e.g., backup DF) that identifies the second PE device as a “protector” of the Ethernet segment. For example, a routing component of the DF configures within a forwarding component a backup path to the second PE device, e.g., installing the label and operation(s) within the forwarding component to cause the forwarding component to add the label to BUM packets received from a core network. Therefore, when an access link to the local CE device has failed, the DF reroutes BUM packets from the core network via the backup path to the second PE device, which sends the BUM packets to the CE device.

    Abstract: Methods and apparatus relating to the detection of one or more devices in zones, e.g., non-overlapping areas, are described. Individual device locations are made based on RSSI information. Whether a user is determined to be in a zone or not is determined based on location determinations corresponding to the device. Thresholds used to determine whether a device is to be considered as being within a zone differs depending on whether the device is newly detected in the zone or is already determined to be in the zone. In some embodiments it is easier to be determined to be in a zone than to be determined to have left a zone. A device may be determined to be in two non-overlapping zones at the same time thereby increasing the chance that devices in edge areas will be counted with regard to the number of devices for which resources should be provided.
