A system receives, from one or more subsystems, one or more predicted outcomes associated with a device. The system provides provide at least a subset of the predicted outcomes as input to a machine learning model trained to identify a set of resolution actions. The system receives, from the machine learning model, the set of resolution actions for the subset of the predicted outcomes, wherein each resolution action in the set of resolution actions is associated with a probability of resolving at least one of the predicted outcomes in the subset of predicted outcomes. The system identifies a first resolution action from the set of resolution actions, wherein the first resolution action has a highest probability of resolving the at least one of the predicted outcomes in the subset of predicted outcomes. The system provides a first instruction to execute the first resolution action.

A method and system for packet tracing is described. In one embodiment, a method includes selecting a packet for tracing through a cluster of a plurality of nodes. The method includes preparing the packet for tracing by generating a cluster-wide unique ID, associating the unique ID with the packet, generating a running counter, and associating the counter with the packet. The method includes generating a first record buffer on a first node of the plurality of nodes and recording the unique ID and an initial value of the counter. The method includes recording a description of an operation performed on the packet in the first record buffer along with a value of the counter. The method also includes transferring the packet to a second node, along with the unique ID, the value of the running counter, and an attribute that indicates that the packet is to be traced.

A method and system for managing performance of over a multimedia content distribution network (MCDN), such as a digital subscriber line network, involves receiving an indication of an impairment in network performance from an MCDN client. The MCDN node associated with the client may be identified and a community of MCDN clients coupled to the MCDN node may be further identified. Impairment information, representative of MCDN equipment, may be collected for each of the MCDN clients. Detailed network diagnostics and field service may be performed for MCDN clients based on a characterization of the impairment parameters. After remediation of the MCDN node, collection of the impairment information may be terminated.

For a network with host machines that are hosting virtual machines, a method for facilitating BUM (broadcast, unknown unicast, and multicast) traffic between a hardware switch (e.g., ToR switch) and the host machines is provided. The network has a set of host machines configured as a cluster of replicators for replicating BUM traffic from the hardware switch to the host machines. A set of network controllers establishes failure-detection tunnels for links between the hardware switch and the replicator cluster. The replicator cluster informs the set of controllers of a change in the membership of the replicator cluster to initiate an update to the active failure-detection sessions. The set of network controllers communicates with the replicator cluster and a ToR switch to establish bidirectional forwarding detection (BFD) sessions between one or more replicator nodes in the replicator cluster and the ToR switch.

The present disclosure provides methods for detecting faults in a distributed computing network system. The method includes receiving, from a management services, authority information identifying peer computing devices of a distributed computing network system. For each respective peer computing device, a first message comprising a first instance of a dataset and a second message comprising a second instance of the dataset are received. Where the first peer computing device and the second peer computing device have authority over the data set, it is determined whether the first instance of the dataset matches the second instance of the dataset. Where the first instance of the dataset does not match the second instance of the dataset, a fault message is sent to the management services indicating that a fault has been detected at the first peer computing device.
