Abstract: In one embodiment, a service receives signal characteristic data indicative of characteristics of wireless signals received by one or more antennas located in a particular area. The service uses the received signal characteristic data as input to a Bayesian inference model to predict physical states of an object located in the particular area. A physical state of the object is indicative of at least one of: a mass, a velocity, an acceleration, a surface area, or a location of the object. The service updates the Bayesian inference model based in part on the predicted state of the object and a change in the received signal characteristic data and based in part by enforcing Newtonian motion dynamics on the predicted physical states.

Abstract: This disclosure describes methods and systems to externally manage network-to-network interconnect configuration data in conjunction with a centralized database subsystem. An example of the methods includes receiving and storing, in the centralized database subsystem, data indicative of user intent to interconnect at least a first network and a second network. The example method further includes, based at least in part on the data indicative of user intent, determining and storing, in the centralized database subsystem, a network intent that corresponds to the user intent. The example method further includes providing data indicative of the network intent from the centralized database subsystem to a first data plane adaptor, associated with the first network, and a second data plane adaptor, associated with the second network.

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.

Abstract: A method includes receiving a DNS request, notifying a serverless orchestrator system of data associated with the DNS request, provisioning a function on a serverless function node based on the DNS request, notifying a load balancer regarding the serverless function node, providing a response to the DNS request and routing an API request associated with the DNS request to the serverless function node.

Abstract: In one embodiment, a service chain data packet is instrumented as it is communicated among network nodes in a network providing service-level and/or networking operations visibility. The service chain data packet includes a particular header identifying a service group defining one or more service functions, and is a data packet and not a probe packet. A network node adds networking and/or service-layer operations data to the particular service chain data packet, such as, but not limited to, in the particular header. Such networking operations data includes a performance metric or attribute related to the transport of the particular service chain packet in the network. Such service-layer operations data includes a performance metric or attribute related to the service-level processing of the particular service chain data packet in the network.

Abstract: In one embodiment, an apparatus includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors. The one or more computer-readable non-transitory storage media include instructions that, when executed by the one or more processors, cause the apparatus to perform operations including determining a path through a plurality of provider nodes within a provider network and determining that the path through the plurality of provider nodes within the provider network is secure. The operations also include receiving, from a customer node, a Resource Reservation Protocol (RSVP) path message comprising an attribute for a security request. The operations further include routing the RSVP path message along the path of the plurality of provider nodes.

Abstract: The present technology pertains to a system that authenticates the identity of a user trying to access a service. The system comprises an authentication provider configured to communicate authentication requirements to a continuous multifactor authentication device and the continuous multifactor authentication device configured to receive authentication requirements, to fuse multiple identification factors into an identification credential for a user according to the authentication requirements, and to send the authentication credential to the authentication provider. After receiving the identification credential meeting the authentication requirements, the authentication provider is configured to instruct a service provider to initiate a session.

Abstract: Systems, methods, and computer-readable storage media are provided for managing application traffic. A routing policy defines the data flow path between the client device (which uses a virtual private network (VPN) client) and the appropriate network-based service. Based on various factors associated with the user, the client device, and the destination (e.g. network-based service), the routing policy will direct the VPN client to communicate with either a public DNS (via the public Internet) or to a private DNS (via the private Intranet). The resulting IP addresses will be used to establish a particular route (either over a public Internet or private Intranet) between the client device and the network-based service in accordance to the routing policy.

Abstract: In one embodiment, for each distribution period of time, each packet flow is assigned to a path through a packet switching device (e.g., switch fabric) with all packets of the packet flow being sent in order over the assigned path. For a next distribution period, different paths are assigned for these packet flows, with all packets being sent in order over the new corresponding selected path. In one embodiment, these paths are switched often enough to prevent congestion, yet infrequent enough so as to minimize resources for reordering. In one embodiment, the reordering is done at the egress and only for predefined high bandwidth flows (e.g., elephant flows). A distribution period indication is typically associated with each packet to identify its corresponding distribution period. In one embodiment, each routing and egress switching stage in a switching fabric performs reordering.
