  • Patent number: 11966413
    Abstract: In one embodiment, a first deep fusion reasoning engine (DFRE) agent in a network receives first sensor data from a first set of one or more sensors in the network. The first DFRE agent translates the first sensor data into symbolic data. The first DFRE agent applies, using a symbolic knowledge base maintained by the first DFRE agent, symbolic reasoning to the symbolic data to make an inference regarding the first sensor data. The first DFRE agent updates, based on the inference regarding the first sensor data, the knowledge base. The first DFRE agent propagates the inference to one or more other DFRE agents in the network.

  • Publication number: 20240106679
    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.

  • Patent number: 11895042
    Abstract: Resource provider specifications, characterizing computing resources of computing resource providers, are received. The reachability of each IP address included in the received specification is determined. An agent is deployed that is operable to determine the value of each of a set of metrics in the environment of the host at which the agent is deployed. The agent determines the value of each metric of the set of metrics in the environment of the relevant host, and communicates the determined values to one or more computing devices that validate whether the resources characterized by the communicated values are sufficient to provide the performance characterized by the received specification and that each ISP router complies with a predetermined policy. For each computing resource provider validated and determined to comprise an ISP router compliant with policy, the specified computing resources are added to a pool of resources for cloud computing.

  • Publication number: 20240031350
    Abstract: An enclave manager of a network enclave obtains a request to retrieve configuration information and state information corresponding to compute devices and network devices comprising a network enclave. The request specifies a set of parameters of the configuration information and the state information usable to generate a response to the request. The enclave manager evaluates the compute devices, the network devices, and network connections among these devices within the network enclave to obtain the configuration information and the state information. Based on the configuration information and the state information, the enclave manager determines whether the network enclave is trustworthy. Based on the parameters of the request, the enclave manager generates a response indicating a summary that is used to identify the trustworthiness of the network enclave.

  • Publication number: 20230394370
    Abstract: Systems, methods, and computer-readable for cognitive sensor fusion management include obtaining one or more data streams from one or more sensors. Learning algorithms are used for determining whether a combination of the one or more data streams includes sufficient information for achieving a desired outcome, based on context, business verticals, or other considerations. One or more modifications are determined to at least the one or more data streams or one or more sensors based on whether the combination of the one or more data streams includes sufficient information for achieving the desired outcome. In a closed-loop system, feedback from implementing the one or more modifications can be used to update the desired outcome.

  • Publication number: 20230370526
    Abstract: Techniques for devices in autonomous systems to utilize a protocol, such as a Border Gateway Protocol (BGP), to signal intent to instantiate services for establishing connections between the devices. For instance, first device(s) in a first autonomous system (AS) may determine to establish a connection with a second AS. The first device(s) may encode a service key into an Internet Protocol (IP) address where the service key indicates a service that is to be provisioned on second device(s) in the second AS. The first device(s) system may then advertise the IP address host-route using BGP, and the second device(s) may receive the BGP advertisement. The second device(s) may decode the service key from the IP address, and provision the service to establish the connection between the autonomous systems. Thus, the devices in may leverage existing protocols to signal intent to instantiate services and establish connections between autonomous systems.

  • Publication number: 20230370382
    Abstract: In one embodiment, an offload platform is an compute platform, adjunct to a router or other packet switching device, that performs packet processing operations including determining an egress forwarding value corresponding to the next-hop node of the packet switching device to which to send an offload-platform processed packet. The offload platform downloads forwarding information from the router, and augments it, such as, but not limited to, representing interfaces of the router as identifiable virtual interface(s) on the offload platform, and including each of one or more next-hop nodes of the router represented as an identifiable virtual adjacency and identifiable tunnel (e.g., identified by the egress forwarding value). In one embodiment, the egress forwarding value is an Multiprotocol Label Switching (MPLS) label or Segment Routing Identifier. The router identifies packets of certain packet flows to send to the adjunct offload platform, rather than processing per its routing information base.

  • Patent number: 11785053
    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.

  • Patent number: 11715304
    Abstract: In one embodiment, a video analysis service receives video data captured by one or more cameras at a particular location. The service applies a neural network-based model to portions of the video data, to identify objects within the video data. The service maps outputs of the neural network-based model to symbols using a conceptual space. The outputs of the model comprise the identified objects. The service applies a symbolic reasoning engine to the symbols, to generate an alert. The service sends the alert to a user interface in conjunction with the video data.

  • Patent number: 11687798
    Abstract: In one embodiment, a deep fusion reasoning engine receives network telemetry data collected from a network. The deep fusion reasoning engine learns resource utilizations for different heuristic packages that can be used in the network to evaluate operation of the network. The deep fusion reasoning engine selects one of the heuristic packages based on the resource utilizations learned for the different heuristic packages. The selected heuristic package comprises a subservice and a set of rules to be evaluated. The deep fusion reasoning engine deploys the selected heuristic package for execution by a device in the network to evaluate operation of the network using the set of rules.
