  • Patent number: 11936564
    Abstract: Techniques for a TCP proxy to communicate over a LEO satellite network on behalf of a client device by selecting a TCP congestion-control algorithm that is optimal for the LEO satellite network based on the time of day and/or location of the TCP proxy. Based on the locations of satellites during the day as they traverse predefined and patterned orbital paths, different TCP congestion-control algorithms may be more optimized to communicate data through the LEO satellite network. However, client devices generally use a single TCP congestion-control algorithm to communicate over WAN networks. Accordingly, a TCP proxy may be inserted on, for example, a router to communicate with the client device using a TCP congestion-control algorithm that the client device is configured to use, but then communicate over the LEO satellite network using a different TCP congestion-control algorithm that is optimal based on the time of day and/or other factors.

  • Patent number: 11936559
    Abstract: One technique includes receiving, in a first network, a multi-destination packet from a second network, and determining, based on the multi-destination packet, a first multi-destination tree in the first network for forwarding the multi-destination packet. In response to determining that the first multi-destination tree is not rooted on the network device, a second multi-destination tree in the first network is determined, and the multi-destination packet is transmitted using the second multi-destination tree. Another technique includes, upon detecting a first network device joining a network, sending a first indication to a second network device that the first network device is in a state for an amount of time. After the amount of time has elapsed, a second indication that the first network device has exited the state is sent to the second network device. A topology of the network is updated after the first network device has exited the state.

  • Patent number: 11929849
    Abstract: Techniques for ensuring symmetric forwarding between disparate networks. The techniques may include receiving a gateway preference order associated with a route advertised by an edge node, the edge node associated with a first network. The techniques may also include determining, based at least in part on the gateway preference order, that a gateway node is a more preferred gateway for the route than another gateway node, the gateway node configured to facilitate communications between the first network and a second network. In some examples, the techniques may also include converting the gateway preference order into a metric associated with an IP routing protocol that is in use in the second network. In some examples, the route including the metric may be distributed within the second network such that the gateway node is the more preferred gateway for return traffic of the route.

  • Patent number: 11930000
    Abstract: Techniques for training and using models to analyze multiple attributes of an authentication, and detect anomalous authentications that may include security threats. An authentication platform may use historical authentication data to train models to identify common attributes for authentications of users, and the training may be performed without the use of labels. For instance, models may be trained for each attribute of the historical authentications (e.g., geographic location, type of authentication method, type of device, time of day, etc.) to “learn” common behaviors of users across attributes of historical authentications. The models can then be applied to new authentications to determine, on an attribute-by-attribute level, whether or not new authentications are anomalous as compared to historical authentications by the user.

  • Patent number: 11930069
    Abstract: Techniques for determining whether HTTP/2 or HTTP/3 is a preferred protocol for communication between a client device and a server over a network are described. A change associated with a network interface of a client device is detected. Based at least in part on detecting the change, a determination is made to identify a preferred communication protocol for a network over which the client device communicates using the network interface. A HTTP/2 probe is transmitted over the network and to a server. A HTTP/3 probe is transmitted over the network and to the server. In response to not receiving a HTTP/3 probe response, the preferred communication protocol is determined to be HTTP/2. In response to receiving the HTTP/2 probe response and the HTTP/3 probe response, the preferred communication protocol is determined to be HTTP/3. The client device communicates with the server over the network using the preferred communication protocol.

  • Patent number: 11930541
    Abstract: In one embodiment, an access point of an overhead mesh of access points in an area selects a range of client identifiers. The access point sends, via a beam cone transmitted in a substantially downward direction towards a floor of the area, a trigger signal that includes the range of client identifiers and prompts client devices having identifiers in that range to send best effort transmissions towards the overhead mesh. The access point detects a collision between the best effort transmissions of the client devices. The access point adjusts the range of client identifiers so as to avoid future collisions between the best effort transmissions of the client devices.

  • Patent number: 11929906
    Abstract: Techniques for a head-end node in one or more network autonomous systems to utilize a protocol to instantiate services on tail-end nodes. The head-end node can use a service request mechanism that is enabled by the protocol to request service instantiation on the tail-end node without a network operator having to manually configure the tail-end node, or even having access to the tail-end node. Additionally, the protocol may provide mechanisms to define handling attributes for traffic of the service (e.g., quality of service (QoS) attributes, Maximum Transmission Unit (MTU) settings, etc.), service acknowledgement mechanisms for the head-end node to determine that the service was instantiated on the tail-end node, and so forth. In this way, a head-end node can be used to instantiate a service on a tail-end node without a network operator having to have direct access to the tail-end node to manually configure the tail-end node.

  • Patent number: 11922216
    Abstract: Techniques and mechanisms for managing workloads in compute clusters comprising compute nodes by managing the workloads at the resource level of the compute clusters. For example, virtual service contexts (VSCs) may be defined where the VSCs represent service classes. Policies may be defined with respect to each service class. These service classes are dynamically constructed based on business needs. Hence there is natural requirement for a user to construct and rebalance the compute resources for these service classes dynamically. The policies may be related to resources of the compute clusters for executing workload units in the compute clusters. Resources of the compute clusters may be allocated to each service class. Each workload unit may be assigned to a one of the service classes based on the service context or type of workload unit. The workload units may then be executed by the compute clusters using the resources in accordance with the policies.
