  • Patent number: 11374660
    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: 11375398
    Abstract: In one embodiment, a client device having a plurality of radios obtains a list of basic service set identifiers (BSSIDs) for a plurality of wireless access points of a wireless network. The client device associates each of the plurality of radios of the client device with a different wireless access point of the wireless network, based on the obtained list of BSSIDs. The client device receives a copy of a data packet from a particular one of the associated wireless access points. Each of the associated wireless access points receives a replicated copy of the data packet to be transmitted towards the client device. The device causes the associated wireless access points to cease further transmission of their copies of the data packet by acknowledging receipt of the data packet to the particular wireless access point.

  • Patent number: 11374806
    Abstract: Systems, methods, and computer-readable media for providing cross-domain assurance for networks in different network domains. In some embodiments, a method can include collecting first fabric data for a first network in a first network domain and second fabric data for a second network in a second network domain. The second fabric data for the second network can be normalized based on the first network domain to create normalized second fabric data. The first fabric data can then be correlated with the normalized second fabric data to create correlated fabric data. Subsequently, assurance can be provided across the first network in the first network domain and the second network in the second network domain using the correlated fabric data.

  • Patent number: 11368378
    Abstract: Systems, methods, and computer-readable media for identifying bogon addresses. A system can obtain an indication of address spaces in a network. The indication can be based on route advertisements transmitted by routers associated with the network. The system can receive a report generated by a capturing agent deployed on a host. The report can identify a flow captured by the capturing agent at the host. The system can identify a network address associated with the flow and, based on the indication of address spaces, the system can determine whether the network address is within the address spaces in the network. When the network address is not within the address spaces in the network, the system can determine that the network address is a bogon address. When the network address is within the address spaces in the network, the system can determine that the network address is not a bogon address.
