  • Patent number: 11979744
    Abstract: Federation policy exchange is provided in response to receiving a sharing query from an Access Point (AP) indicating that an associated wireless network supports federated identities with data sharing, determining whether the sharing query is within sharing preferences; and in response to determining that the sharing query is within the sharing preferences, transmitting, to the AP, a positive response for identity sharing that authorizes collection and sharing of identity data with at least one entity identified in a sharing policy for the associated wireless network. In various embodiments, federation policy exchange includes transmitting a support notification, via an AP, indicating support for federated identities with data sharing within a wireless network associated with the AP; and in response to receiving a first identify sharing preference from a User Equipment (UE) that indicates that negotiation is preferred, transmitting a sharing policy for the wireless network to the UE.

  • Patent number: 11979298
    Abstract: In one embodiment, a device trains, using feedback from a reference cohort of users of an online application, a prediction model to predict a quality of experience metric for the online application based on network telemetry. The device uses the prediction model to predict quality of experience metrics for different cohorts of users of the online application. The device makes one or more comparisons between performance metrics for the prediction model for the different cohorts of users, based on the quality of experience metrics predicted for the different cohorts of users. The device retrains, based on the one or more comparisons, the prediction model using feedback from the reference cohort and a particular cohort from among the different cohorts of users.

  • Patent number: 11979384
    Abstract: This disclosure describes using a dynamic proxy for securing communications between a source within a cloud environment and an application container. The techniques include intercepting traffic directed to an application container, analyzing the traffic and traffic patterns, and allowing or preventing the traffic from being delivered to the application container based on the analysis. A traffic analysis engine may determine whether the traffic is considered safe and is to be allowed to be delivered to the application container, or whether the traffic is considered unsafe and is to be prevented from being delivered to the application container, According to some configurations, the address(es) to the network interfaces (e.g., WIFI or Eth0) are abstracted to help ensure security of the application containers.

  • Patent number: 11979412
    Abstract: Techniques to facilitate verification of in-situ network telemetry data of data packet of data traffic of packet-switched networks are described herein. A technique described herein includes a network node obtaining a data packet of data traffic of a packet-switched network. The data packet includes an in-situ network telemetry block. The network node obtains telemetry data and cryptographic key. The cryptographic key confidentially identifies the network node. The node encrypts at least a portion of the telemetry data based on the cryptographic key to produce signed telemetry data and updates telemetry-data entry of the in-situ network telemetry block. The telemetry data and signed telemetry data is inserted into the telemetry-data entry. The node forwards the data packet with the updated telemetry-data entry to another network node of the packet-switched network.

  • Patent number: 11979310
    Abstract: Techniques are provided for signal translation in a hybrid network environment. In one example, a first provider edge node obtains a connection status indication from a first one of a second provider edge node via a packet switched network or a third provider edge node via a time-division multiplexing transport network. The first provider edge node translates the connection status indication between a packet switched network format and a time-division multiplexing transport network format. The first provider edge node provides the connection status indication to a second one of the second provider edge node via the packet switched network or the third provider edge node via the time-division multiplexing transport network.

  • Patent number: 11979366
    Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a virtual IP (VIP) address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a virtual network of VIP addresses. The client device may then communicate data packets to the server using the VIP address as the destination address, and a virtual network service that works in conjunction with DNS can convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.

  • Patent number: 11979311
    Abstract: In one embodiment, a device receives, via a user interface, an indication of what is considered noise within a time series of a path performance metric. The device selects, based on the indication, a particular denoising filter to be applied to telemetry data obtained from one or more network paths regarding the path performance metric. The device forms model training data by applying the particular denoising filter to telemetry data obtained from one or more network paths regarding the path performance metric. The device trains, using the model training data, a prediction model to predict when a given network path will experience a failure condition.

  • Patent number: 11979430
    Abstract: In one embodiment, a telemetry exporter in a network establishes a tunnel between the telemetry exporter and a traffic analysis service. The telemetry exporter obtains packet copies of a plurality of packets sent between devices via the network. The telemetry exporter forms a set of traffic telemetry data by discarding at least a portion of one or more of the packet copies, based on a filter policy. The telemetry exporter applies compression to the formed set of traffic telemetry data. The telemetry exporter sends, via the tunnel, the compressed set of traffic telemetry data to the traffic analysis service for analysis.

  • Patent number: 11979375
    Abstract: Techniques for a context-aware secure access service edge (SASE) engine for generating security profile(s) associated with endpoint device(s) accessing the network and using the security profile(s) to evaluate a traffic flow from the endpoint device(s). The SASE engine may execute on an edge device of a computing resource network and may be configured to maintain a security profile database including an endpoint security profile mapping. Endpoint device(s) accessing the network may share endpoint, application, and/or user specific information with the SASE engine so that the SASE engine may generate a security profile specific to the endpoint, application, and/or user. Additionally, an enterprise network, associated with endpoint device(s) accessing the network, may provide default SASE security profile templates to the SASE engine.

  • Patent number: 11979862
    Abstract: Providing for time sensitive networking (TSN) traffic in high density deployments is described. An access point (AP) is a high density deployment receives a message identifying another AP as a TSN neighbor and also detects a TSN device within an area covered by the APs. This arrangement may cause traffic interruptions for the TSN traffic between the TSN device and the APs. In order to prevent disruption in TSN traffic, a TSN time slot and a resource unit (RU) is determined for each of the APs, and the TSN traffic is communicated between the various devices in network according to the determined TSN time slot and RU.
