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.

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: 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.

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.

Abstract: In one embodiment, a service receives signal data indicative of phases and gains associated with wireless signals received by one or more antennas located in a particular area. The service determines, from the received signal data, changes in the phases and gains associated with the wireless signals. The service estimates a direction of motion of one or more objects located in the particular area, based on the determined changes in the gains associated with the wireless signals. The service estimates a total mass of the one or more objects located in the particular area based on a ratio of the determined changes in the gains associated with the wireless signals over the determined changes in the phases associated with the wireless signals.

Abstract: In one embodiment, a method includes a method includes receiving, by a headend node, network traffic. The method also includes determining, by the headend node, that the network traffic matches a service route. The method further includes steering, by the headend node, the network traffic into an SR-TE policy. The SR-TE policy is associated with the service route and includes a security level constraint.

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 identifies an object in the particular area, based on the received signal characteristic data. The service associates the identified object with an object kinematics model. The service updates the object kinematics model over time by applying Bayesian inference to changes in the signal characteristic data.

Abstract: A verifier peer system transmits a request to an application of another peer system to obtain integrity data of the application. In response to the request, the verifier peer system obtains a response that includes kernel secure boot metrics of the other peer system and integrity data of the application and of any application dependencies. If the verifier peer system determines that the response is valid, the verifier peer system evaluates the integrity data and the kernel secure boot metrics against a set of Known Good Values to determine whether the integrity data and the kernel secure boot metrics are valid. If the integrity data and the kernel secure boot metrics are valid, the verifier peer system determines that the other peer system is trustworthy.

Abstract: In one embodiment, a network node automatically cycles among packet traffic flows and subjects the currently selected packet flows to varying drop probabilities in a packet network, such as, but not limited to in response to congestion in a device or network. Packets of a currently selected packet traffic flow are subjected to a drop or forward decision with a higher drop probability than packets of a currently non-selected flow. By cycling through all of these packet traffic flows, all of these packet flows are subjected to the drop or forward decision in the long term approximately uniformly, thus providing fairness to all packet traffic flows. In the short term, packets of a currently selected flow are targeted for possible dropping with a higher drop probability providing unfairness to the currently selected flows over the non-selected flows.

Abstract: In one embodiment, a service that monitors a network detects a plurality of anomalies in the network. The service uses data regarding the detected anomalies as input to one or more machine learning models. The service maps, using a conceptual space, outputs of the one or more machine learning models to symbols. The service applies a symbolic reasoning engine to the symbols, to rank the anomalies. The service sends an alert for a particular one of the detected anomalies to a user interface, based on its corresponding rank.
