Abstract: Methods are provided in which a domain name system (DNS) service obtains a lookup request for information about a source of a traffic flow being transmitted to a network resource external of a service cluster and performs, based on the lookup request, a lookup operation for a microservice that is the source of the traffic flow, among a plurality of microservices of the service cluster registered with the DNS service. The methods further include providing information about the microservice based on the lookup operation. The information includes at least a name of the microservice for visibility of the microservice external of the service cluster.

Abstract: In one embodiment, an access policy enforcement service receives a user authentication request from an end-user device. The access policy enforcement service identifies a telemetry collection intent from the user authentication request. The access policy enforcement service determines a monitoring policy based on the telemetry collection intent identified from the user authentication request. The access policy enforcement service configures, according to the monitoring policy, one or more telemetry collection agents to collect telemetry for traffic associated with the end-user device.

Abstract: This disclosure describes techniques for predicting and accommodating for outages in a satellite network using crowdsourced data. An example method includes receiving outage data indicating first outages experienced by first endpoints in a first geographical region. The first outages, for instance, include interruptions in communication between first satellites and the first endpoints. The example method further includes predicting, based on the outage data, a second outage comprising an interruption in communication between at least one second satellite and a second endpoint in a second geographical region. Further, the example method includes causing the second endpoint to transmit user data over a secondary network in advance of the second outage.

Abstract: Techniques are provided for an “on demand” or event-triggered end user monitoring/remote user monitoring (EUM/RUM) solution that is activated when the user has requested it, or an event (conditions of which are set by a user) occurs that triggers activation of the EUM/RUM solution. This EUM/RUM may be completely integrated into an enterprise IT Help Desk system, whereby support “tickets” are automatically generated when the monitoring solution is instantiated.

Abstract: Techniques for a TCP proxy to communicate over a LEO satellite network on behalf of a client device by selecting a TCP congestion-control algorithm that is optimal for the LEO satellite network based on the time of day and/or location of the TCP proxy. Based on the locations of satellites during the day as they traverse predefined and patterned orbital paths, different TCP congestion-control algorithms may be more optimized to communicate data through the LEO satellite network. However, client devices generally use a single TCP congestion-control algorithm to communicate over WAN networks. Accordingly, a TCP proxy may be inserted on, for example, a router to communicate with the client device using a TCP congestion-control algorithm that the client device is configured to use, but then communicate over the LEO satellite network using a different TCP congestion-control algorithm that is optimal based on the time of day and/or other factors.

Abstract: A method is provided that is performed using an application performance management agent running on an application and/or application microservices. The method comprises detecting a request to the application and/or application microservices for data, and inserting data compliance metadata into packet headers of packets that are to be sent in response to the request by the application and/or application microservices. The data compliance metadata comprises data-compliance markings associated with the data based on user/operator-defined data compliance requirements. The method further includes causing the packets to be sent into a network so that one or more network devices or services in the network can read the data compliance metadata and apply packet handling policies.

Abstract: Techniques for expressing, communicating, de-conflicting, and enforcing consistent access policies between an IBN architecture and a Cloud-Native architecture. Generally, network administrators and/or users of a Cloud-Native architecture and an IBN architecture express access policies independently for the two different domains or architectures. According to the techniques described herein, a Network Service Endpoint (NSE) of the Cloud-Native architecture may exchange access policies with a network device of the IBN architecture. After exchanging access policies, conflicts between the sets of access policies may be identified, such as differences between allowing or denying communications between microservices and/or applications. The conflicts may be de-conflicted using various types of heuristics or rules, such as always selecting an access policy of the IBN architecture when conflicts arise. After the access policies have been de-conflicted, the IBN architecture and Cloud-Native architecture may then apply consistent access policies for traffic and communications in their respective network architectures.

Abstract: Systems, methods, and computer-readable media are disclosed for proactively and adaptively rerouting data to a healthier path through network, as part of flow provisioning, based on environmental variables associated with devices in the network. The present technology includes identifying a routing path for forwarding traffic flows in a network, receiving diagnostic data of a routing device on the routing path. The diagnostic data include one or more environmental parameters associated with internal state and surroundings of the routing device. Further, the present technology includes comparing the diagnostic data of the routing device with a predetermined threshold and modifying, prior to a failure of the routing device, the routing path to bypass the routing device for at least a portion of the traffic flows based on the comparison between the diagnostic data of the routing device and the predetermined threshold.

Abstract: A first connection is established between a meeting server and a first endpoint device associated with a user. At least one multimedia stream for an online collaborative session is provided from the meeting server to the first endpoint device. The meeting server obtains an indication that a first strength of a first short-range wireless communication connection between an audio device and the first endpoint device is less than a second strength of a second short-range wireless communication connection between the audio device and a second endpoint device associated with the user. A second connection is established between the meeting server and the second endpoint device. The at least one multimedia stream is provided from the meeting server to the second endpoint device via the second connection in response to obtaining the indication.
