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.

Abstract: A method comprises obtaining, from a client device, a first set of application authentication credentials formatted in accordance with a first authentication protocol. The first set of application authentication credentials corresponds to a first user profile. The method includes translating the first set of application authentication credentials to a second set of application authentication credentials. The second set of application authentication credentials is formatted in accordance with a second authentication protocol different from the first authentication protocol and corresponds to the first user profile. The method includes providing the second set of application authentication credentials to an application authentication system. The method includes, in response to providing the second set of application authentication credentials to the application authentication system, obtaining, from the application authentication system, an application authentication indicator. In response to determining that the application authentication indicator indicates a successful authentication, granting the client device network access.

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 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.
