Various embodiments herein described are directed to methods, apparatuses and computer program products configured for improving alert generation and management in network computer systems. In some embodiments, a client device may generate one or more responder alert data objects for an incident data object based at least in part on global alert policy data object(s) and inline alert policy data object(s). Additional example embodiments provide various example global alert policy creation user interfaces, global alert policy edit user interfaces, inline alert policy creation user interfaces, and/or inline alert policy edit user interfaces that facilitate various user inputs and software operations in an incident alert and management platform.

A communication device including a first communication device and a plurality of second communication devices in an optical access system in which a first communication device and the plurality of second communication devices perform communications with each other under a time division multiple access scheme includes an Ethernet controller configured to implement the communications as Ethernet (registered trademark) communications, and a link failure processing unit configured to output, in response to reception of a link failure notification for notifying occurrence of a link failure in the communications from the first communication device, a termination instruction to terminate data transmission when the communication device is performing the data transmission to the first communication device, and a start instruction to start the data transmission after recovery from the link failure when the communication device is not performing the data transmission to the first communication device.

Systems and methods include receiving Operations, Administration, Maintenance, and Provisioning (OAM&P) data from an optical network; providing a Graphical User Interface (GUI) based on the OAM&P data with the GUI including a topology view; and providing a visualization that includes one of a power readings graph, a spectral analysis graph, and a spectral allocation graph, in the GUI, and the visualization is positioned logically next to the topology view.

Methods and systems to detect and resolve failure in a distributed database system is described herein. A first node in the distributed database system can detect an interruption in communication with at least one other node in the distributed database system. This indicates a network failure. In response to detection of this failure, the first node starts a failure resolution protocol. This invokes coordinated broadcasts of respective lists of suspicious nodes among neighbor nodes. Each node compares its own list of suspicious nodes with its neighbors' lists of suspicious nodes to determine which nodes are still directly connected to each other. Each node determines the largest group of these directly connected nodes and whether or not it is in that group. If a node isn't in that group, it fails itself to resolve the network failure.

A method for operating a telecom network having an SLA agreement is disclosed. The method comprises obtaining annotated alarm data comprising an indication of a threshold crossing of at least one state variable of the telecom network defined by the SLA. The annotated alarm data further comprises an indication of a desired value of the at least one state variable of the telecom network. Moreover, the method comprises determining a desired state of the telecom network based on the desired value of at least one state variable, and selecting a set of policy actions from a policy action bank. The policy action bank comprises a plurality of policy actions, where each policy action is associated with at least one estimated action effect. The selection of the set of policy actions is accordingly based on the estimated action effects of the plurality of policy actions and on the determined desired state of the telecom network such that the desired state is reachable upon execution of the selected set of policy actions. The method further comprises

A topology configuration tool for optimizing resources to meet requirements. The tool may use a derivation of the composite service outage and restoral rates as a function of the number of servers, the number of sites, and the minimum required server capacity level, using an adaptation of the hyper-geometric “balls in urns” distribution with unequally likely combinations.

Systems and methods for application performance management across one or more networks are disclosed. A system includes a plurality of geographically distributed computing devices executing one or more applications. A plurality of collectors are distributed across the one or more networks, each collector being positioned proximate a respective computing device. The collectors may sample, by each of the plurality of collectors, a plurality of trace events received from the applications executing on the computing devices proximate the collector. The collectors may retain in memory sampled trace events that meet a configurable attribute. The collectors may use probabilistic sets and tail-based sampling to determine root events and policies for identifying relevant traces. Benefits can be achieved in bandwidth savings, network cost and cyber security.

The invention relates to coordination of network function, NF, consumers subscribing to analytics events from a second network node. According to embodiments of the invention procedures for suppressing the notification related to an analytics event for specific NF consumers are introduced. The procedures are performed between a first network node and the second network node, where the first network node 100 may be seen as a controlling function and the second network node may be seen as a controlled function. The procedures are based on a list of NF consumers subscribing to an analytics event and their respective notification status associated with the analytics event. Depending on the list of NF consumers, the second network node may transmit or suppress notifications associated with the analytics event to the NF consumers.
