  • Patent number: 10887197
    Abstract: In one embodiment, a network quality assessment service that monitors a network obtains multimodal data indicative of a plurality of measurements from the network and subjective perceptions of the network by users of the network. The network quality assessment service uses the obtained multimodal data as input to one or more neural network-based models. The network quality assessment service maps, using a conceptual space, outputs of the one or more neural network-based models to symbols. The network quality assessment service applies a symbolic reasoning engine to the symbols, to generate a conclusion regarding the monitored network. The network quality assessment service provides an indication of the conclusion to a user interface.

  • Patent number: 10887799
    Abstract: In one illustrative example, a user plane (UP) entity for use in a mobile network may receive a data packet from a user equipment (UE) operative to communicate in one or more sessions via a serving base station (BS) (e.g. eNB or gNB) of the mobile network. The UP entity may detect, in a header (e.g. SRH) of the data packet, an identifier indicating a new serving BS or session of the UE. The identifier may be UE- or BS-added data (e.g. iOAM data) that is inserted in the header by the UE or BS. In response, the UP entity may cause a message to be sent to an analytics function (e.g. a NWDAF) to perform analytics for session or flow migration for the UE.

  • Publication number: 20200412846
    Abstract: In one embodiment, new Segment Routing capabilities are used in the steering of packets through Segment Routing nodes in a network. A Segment List includes a set of one or more Segment List (SL) Groups, each of which identifies one or more Segments contiguously or non-contiguously stored in the Segment List (or stored across multiple Segment Lists) of a Segment Routing packet. Each SL Group typically includes one Segment that is encoded as a Segment Identifier, and may include Segments that are Extended Values. The steering order of SL Groups is not required to be the same order as they are listed in the Segment List, as the value of Segments Left may be increased, remain the same, or decreased (possibly to skip a next SL Group) and possibly based on the result of an evaluation of a conditional expression.

  • Patent number: 10880016
    Abstract: In one example embodiment, a server obtains a labeled fingerprint of an ultrasound-capable client device. Based on the labeled fingerprint, the server determines that the ultrasound-capable client device is in physical proximity with a collaboration endpoint. The server subsequently obtains an unlabeled fingerprint of an ultrasound-incapable client device. Based on the unlabeled fingerprint and the labeled fingerprint, the server determines that the ultrasound-incapable client device is a meeting attendee device for a collaboration meeting to which the collaboration endpoint is connected. In response to determining that the ultrasound-incapable client device is the meeting attendee device for the collaboration meeting, the server connects the ultrasound-incapable client device to the collaboration endpoint.

  • Patent number: 10880186
    Abstract: In one embodiment, a supervisory service for a software-defined wide area network (SD-WAN) detects seasonal service level agreement (SLA) violations by one or more tunnels in the SD-WAN using a machine learning-based regression model. The service identifies a root cause of the seasonal SLA violations by determining whether the root cause of the seasonal SLA violations is associated with an internal network connected to the one or more tunnels. The service further identifies the root cause by determining whether the root cause of the seasonal SLA violations is associated with a particular service provider network over which the one or more tunnels traverse by associating the seasonal SLA violations with SLA violations by tunnels in other SD-WANs that also traverse the particular service provider network. The service initiates a corrective measure based on the determined root cause of the seasonal SLA violations by the one or more tunnels.

  • Patent number: 10880203
    Abstract: In one embodiment, a server has connectivity to a network that includes a plurality of nodes. The server stores a context identifier that is associated with backup path information stored at a particular node of the plurality of nodes, the backup path information indicating a backup path in the network. The server sends to the particular node a probe packet having a data plane instruction label that includes an identifier of the particular node, the context identifier and server identifier information. The context identifier in the probe packet causes the particular node to retrieve the backup path information and send the probe packet to a next hop node in the backup path based on the backup path information. The server determines whether the probe packet is received at the server after traversing the backup path, and validates the backup path for the particular node accordingly.
