Abstract: Systems and methods for tracking and reporting the existence or absence of faults in a Network Element (NE) or node of a network, network domain, or Maintenance Domain (MD) are provided. A method, according to one implementation, includes a step of tracking the existence or absence of a plurality of faults in a NE within a network domain. Each of the plurality of faults is categorized in one of a plurality of priority levels. In response to a detection of one or more new faults in the NE or a rectification of one or more old faults in the NE, the method further includes the step of updating a fault indication variable that individually signifies the existence or absence of a fault at each of the priority levels.

Abstract: In some examples, a first virtual network function (VNF) that is part of a collection of interconnected VNFs detects a service interruption in a network that includes the collection interconnected VNFs. In response to detecting the service interruption, the first VNF sends control information to a target entity, the control information specifying an action to take to change a communication flow through the collection of interconnected VNFs.

Abstract: Examples of the present disclosure describe systems and methods of dynamically modifying execution environment for varying data or executables. The data or executables may be a multimedia file and the execution environment may be multimedia playback settings. In aspects, content comprising various media items may be received by a client device. The media items may be evaluated to determine a set of characteristics for the media items. The set of characteristics may be compared to a user's preferred configuration settings or previously-played media items. Based on the comparison, the set of characteristics may be altered to be consistent with the preferred configuration settings (e.g., a modified set of characteristics may be estimated). The modified media items may then be played under known playback settings. In aspects, the media item under consideration may be played as is using an estimated playback configuration to enable a user-preferable playback experience.

Abstract: Presented herein are systems, and methods thereof, that is configured to enter a maintenance mode to isolate itself from its neighbor and to gracefully cause neighbor devices to isolate themselves from the system, as to cause minimal or “zero” service disruption with its neighbors. The system broadcasts a maintenance-related message, via a standard transport layer, over routing protocols, to counter parts protocols at the neighbor device and waits for an acknowledgement message from the neighbor network devices. The broadcast and acknowledgement, through standard transport layer messaging, ensures that traffic generated by such protocols at the neighbor devices, regardless of manufacturer, are redirected before the system fully enters into the maintenance mode.

Abstract: Disclosed are various embodiments for scalable notification deliveries in computing environments. A subscription request is transmitted along with a user identifier, a service identifier, a subscription identifier, and a channel identifier. Notifications are communicated through a notification multiplexing channel between two nodes of a computing environment. The notification multiplexing channel includes notifications multiplexed by subscription identifiers. The notification multiplexing channel corresponds to the channel identifier. A notification corresponding to the subscription identifier is identified and provided to a client computing device associated with the user identifier.

Abstract: A reactive buffering system for use in IIoT data pipelines dynamically adjusts data accumulation and delivery by a node of a pipeline based on aggregated downstream metrics representing current data processing latencies of downstream nodes. Based on these downstream performance metrics, a reactive node that adjusts the size of the next data batch to be sent to an adjacent downstream node. The nodes of the data pipeline are configured to support a request-response based handshaking protocol whereby the nodes that send data to downstream nodes maintain up-to-date performance level information from adjacent downstream nodes. With this performance information, together with pipeline priorities, the sending node (or reactive node) adjusts the transmission rate and intermediate buffering of data. In this way, the nodes of the pipeline can dynamically regulate interim data storage to avoid overwhelming the pipeline system with too much data during periods of high latency.

Abstract: The present disclosure relates to computer-implemented methods, software, and systems for detecting isolated zones in a cloud platform. Aggregated data for network connectivity status of web agents at the cloud platform is iteratively collected at a health service. The aggregated data is generated based on network call log data for external accessibility of the web agents. The web agents run at different network segments of the cloud platform. The network call log data is generated based on executed network calls issued from one or more external web agents running outside of the cloud platform and directed to each of the web agents at the cloud platform. A poll request for a network connectivity status for inbound connectivity for an entity running on the cloud platform is received. In response to evaluating the collected aggregated data, the network connectivity status for inbound connectivity for the entity is provided.

Abstract: Techniques discussed herein monitoring for and identifying failures in a cloud-computing environment. Proxy devices can be communicatively disposed between services of the cloud-computing environment. The proxy devices can capture call stack data corresponding to function calls between services. A directional graph can be generated based on that call stack data that represents the communication paths between cloud-computing resources (e.g., the services). Ingress paths to a service can be evaluated by calculating various metrics for each path. Using these metrics, failures can be isolated to a particular communication path and/or a particular, and potentially relatively distant, upstream service.

Abstract: A method includes processing a user input for generating a non-deterministic finite automata tree (NFAT) correlation policy. The user input indicates one or more of a static condition or a dynamic condition for inclusion in the NFAT correlation policy. The static condition includes a comparison between a defined entity and a first fixed parameter. The dynamic condition includes a comparison between the defined entity and a variable parameter. An applicable NFAT element is generated that includes at least one of the NFAT correlation policy generated based on a determination that the user input indicates the static condition or a NFAT template generated based on a determination that the user input indicates the dynamic condition. Event data received from a network device is processed to detect a status of a network entity associated with a communication network based on the applicable NFAT element.
