摘要： In one embodiment, a device in a network performs anomaly detection functions using a machine learning-based anomaly detector to detect anomalous traffic in the network. The device identifies an ability of one or more nodes in the network to perform at least one of the anomaly detection functions. The device selects a particular one of the anomaly detection functions to offload to a particular one of the nodes, based on the ability of the particular node to perform the particular anomaly detection function. The device instructs the particular node to perform the selected anomaly detection function.

摘要： In one embodiment, nodes are polled in a network for Quality of Service (QoS) measurements, and a QoS anomaly that affects a plurality of potentially faulty nodes is detected based on the QoS measurements. A path, which traverses the plurality of potentially faulty nodes, is then computed from a first endpoint to a second endpoint. Also, a median node that is located at a point along the path between the first endpoint and the second endpoint is computed. Time-stamped packets are received from the median node, and the first endpoint and the second endpoint of the path are updated based on the received time-stamped packets, such that an amount of potentially faulty nodes is reduced. Then, the faulty node is identified from a reduced amount of potentially faulty nodes.

摘要： In one embodiment, a first device in a network receives traffic flow data from a plurality of devices in the network. The traffic flow data from at least one of the plurality of devices comprises raw packets of a traffic flow. The first device selects a set of reporting devices from among the plurality of devices based on the received traffic flow data. The first device provides traffic flow reporting instructions to the selected set of reporting devices. The traffic flow reporting instructions cause each reporting device to provide sampled traffic flow data to an anomaly detection device.

摘要： In one embodiment, a packet to be transmitted along a communication path in a network from a source to a destination is determined, the communication path having one or more hops between the source and the destination. An instruction is sent to one or more tracking nodes along the communication path to track a number of local retransmissions required to successfully transmit the packet from each tracking node to a respective next-hop destination. Then, reports indicating the number of local retransmissions are received from the one or more tracking nodes.

摘要： In one embodiment, a capable node in a computer network may host a path computation element, receive one or more neighborhood discovery messages including neighborhood information from a plurality of nodes in the computer network, and compute a minimum spanning tree (MinTree) for the computer network based on the neighborhood information. The MinTree may divide the plurality of nodes in the computer network into a first subset of routing nodes and a second subset of host nodes. The first subset of routing nodes may form one or more interconnected paths of routing nodes within the MinTree, and each host node within the second subset of host nodes may be located within one hop of at least one routing node. The capable node may then communicate a MinTree message to the plurality of nodes in the computer network to build the MinTree by enabling routing on each routing node.
