    Abstract: In general, the disclosure describes techniques for measuring edge-based quality of experience (QoE) metrics. For instance, a network device may construct a topological representation of a network, including indications of nodes and links connecting the nodes within the network. For each of the links, the network device may select a node device of the two node devices connected by the respective link to measure one or more QoE metrics for the respective link, with the non-selected node device not measuring the QoE metrics. In response to selecting the selected node device, the network device may receive a set of one or more QoE metrics for the respective link for data flows flowing from the selected node device to the non-selected node device. The network device may store the QoE metrics and determine counter QoE metrics for data flows flowing from the non-selected node device to the selected node device.

    Abstract: An example network analysis system includes a memory storing telemetry data received from a plurality of network devices, the plurality of network devices includes extract entity information and connectivity information from the received telemetry data, wherein the entity information represents one or more network devices of the plurality of network devices and the connectivity information represents network connections between one or more devices of the plurality of network devices; and store the connectivity information and entity information as a network topology graph in a graph database, wherein the entity information is stored as nodes of the network topology graph and the connectivity information is stored as edges of network topology graph, and wherein the network topology graph represents an organization level topology of the organization network.

    Abstract: Techniques are described for capturing dropped packets and creating modified dropped packets with drop information associated with the dropped packets to provide greater details of the dropped packets for further analysis and/or serviceability. For example, a computing device comprises an internal communication channel, a process executing in user space, and a virtual router. The virtual router comprises, for example, processing circuitry and a drop interface to the internal communication channel, wherein the virtual router is configured to: receive a packet; in response to determining the packet is to be dropped, creating a modified dropped packet to include drop information associated with the packet; and provide the modified dropped packet to the drop interface to communicate the modified dropped packet via the internal communication channel to the process.

    Abstract: A network device may be configured to receive a file stream associated with an file. The network device may be configured to identify, based on receiving the file stream, an initial portion of the file. The network device may be configured to process the initial portion of the file to determine one or more features of the file. The network device may be configured to generate, based on the one or more features of the file, a determination as to whether the file is malicious. The network device may be configured to block or allow, based on the determination, the file stream.
