Abstract: In one embodiment, a device obtains quality of experience metrics for an online application whose traffic traverses a particular interface of a router located at a first site in a network. The device identifies a correlation between throughput of the particular interface and the quality of experience metrics for the online application. The device makes a determination that the correlation is a root cause of degradation of the quality of experience metrics for the online application at least in part by determining whether throughput of an interface of a remote router located at a second site in the network is correlated with the quality of experience metrics. The device configures, based on the determination, a priority queue associated with the particular interface for use by traffic of the online application.

Abstract: Systems and methods are provided for automatically controlling a participant indication request based on a context of a meeting. The controlling of the participant indication request includes automatic lowering of a raised hand. A context determiner determines the context of the meeting based on meeting data including video, audio, background acoustic data, and chat messaging. The context determiner uses a global participant indication model for determining a context that is in commonly used among participants of the meeting. An individual participant indication model captures participant-specific rules of determining a context. A meeting state manager determines a meeting state based on the context. The meeting state includes a host presentation, a participant presentation, a conversation, and a polling. A participant indication controller automatically lowers the raised hand based on a combination of the determined context and the meeting state.

Abstract: A network device transmits, to a server, information of an event that has occurred in the network device, compares, with each of a first threshold and a second threshold greater than the first threshold, a metric that corresponds to a state of the network device pertaining to the event, and switches a method of communicating with the server based on the comparison. When the metric exceeds the first threshold while communicating with the server in a polling method with first communication intervals and is smaller than the second threshold, the method of communicating with the server switches to a polling method with second communication intervals that are shorter than the first communication intervals, and when the metric exceeds the second threshold while communicating with the server in the polling method with the second communication intervals, the method of communicating switches with the server to a push method.

Abstract: Techniques are disclosed relating to identity-based risk evaluation using risk scores for different identities. The disclosed techniques include a server system that provides a service usable to perform computing operations for requesting users. The system may receive a request to perform a particular computing operation from a client device. Based on a name of a user associated with the request, the system assigns an first type of identity that is a birthright identity to the user. Based on details of the request, the system assigns additional identities to the user that are different identity types than the first type of identity. The system may score, based on accessing a risk score database storing known risk information associated with different identity types, the first type of identity and the additional identities. The system may generate a response based on the scoring and transmit the response to the client device.
