Abstract: Techniques are described in which a network management system processes network event data received from the AP devices. The NMS is configured to dynamically determine, in real-time, a minimum (MIN) threshold and a maximum (MAX) threshold for expected occurrences for each event type, wherein the MIN thresholds and MAX thresholds define ranges of expected occurrences for the network events of the corresponding event types. The NMS applies an unsupervised machine learning model to the network event data to determine predicted counts of occurrences of the network events for each of the event types and identify, based on the predicted counts of occurrences and the dynamically-determined minimum threshold values and maximum threshold values for each event type, one or more of the network events as indicative of abnormal network behavior.

Abstract: A network device may forward fragments of an IPv4 network packet encapsulated in IPv6 network packets from an IPv6 network to an IPv4 network without reassembling the IPv4 network packet. The network device may receive and buffer the one or more fragments of a fragment flow associated with the IPv4 network packet until it receives a fragment of the fragment flow that includes an indication of the source port of the IPv4 network packet. When the network device receives the fragment that includes the indication of the source port of the IPv4 network packet, the network device may dispatch each fragment of the fragment flow that it has received to the IPv4 network.

Abstract: Techniques are disclosed for scalable virtualization of tenants and subtenants on a virtualized computing infrastructure. In one example, a first controller for the virtualized computing infrastructure configures underlay network segments in the virtualized computing infrastructure by configuring respective Virtual Extensible Local Area Network (VXLAN) segments of a plurality of VXLAN segments of a VXLAN in a switch fabric comprising network switches. Each VXLAN segment provides underlay network connectivity among a different subset of host computing devices of the virtualized computing infrastructure to enable orchestration of multiple tenants in the VXLAN. A second controller for a first subset of the host computing devices has underlay network connectivity through operation of a first VXLAN segment. The second controller configures overlay networks in the first subset of the host computing devices to enable orchestration of multiple subtenants in the first subset of the host computing devices.

Abstract: A load balancing component may obtain, from a plurality of packet forwarding components of the network device, indications of load balancing metrics associated with a plurality of communication links that the plurality of packet forwarding components use to forward packet data. The load balancing component may determine, based on the load balancing metrics, aggregate load balancing metrics associated with respective communication links of the plurality of communication links. The load balancing component may identify an imbalance in load balancing metrics. The load balancing component may determine, based on the imbalance, a load balancing schedule that indicates traffic distributions for the plurality of packet forwarding components. The load balancing component may provide indications of the traffic distributions to the plurality of packet forwarding components to permit the plurality of packet forwarding components to forward packet data based on the indications of the traffic distributions.

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: Disclosed are embodiments for determining a location of a wireless terminal. The wireless terminal measures signal strength of a plurality of wireless transmitters. Based on this information, a plurality of location probability surfaces are generated. Each location probability surface indicates a plurality of probabilities that the wireless terminal is in each of a corresponding plurality of geographic regions. These probability surfaces are then averaged to determine a composite location probability surface. A motion probability surface is also determined, which stores a plurality of probabilities indicating variations of motion of the wireless terminal. The composite location probability surface is then updated based on the motion probability surface. A location estimate of the wireless terminal is then determined based on the updated composite location probability surface.
