Abstract: Techniques are disclosed for reporting diagnostics data by a first network device to a cloud-based Wide Area Network (WAN) assurance system, responsive to the first network device detecting a communication issue with the cloud-based WAN assurance system. For example, the first network device detects an issue with sending telemetry data to the cloud-based WAN assurance system via a first communication path. In response, the first network device determines a second network device that has connectivity to the WAN assurance system. The first network device sends diagnostics data to the second network device along a second communication path for forwarding to the cloud-based WAN assurance system. The cloud-based WAN assurance system receives the diagnostics data from the second network device. The cloud-based WAN assurance system controls the second network device to remediate the first network device based on the diagnostics data.

Abstract: In an example, a validation system comprises processing circuitry having access to a storage device and is configured to obtain flow records indicative of packet flows among workloads deployed to a cluster of one or more computing devices configured with a network policy, wherein each flow record of the flow records indicates a corresponding packet flow was allowed or denied by the cluster; receive an updated network policy; determine whether a corresponding packet flow for a flow record of the flow records has a discrepancy with the updated network policy; and in response to determining the corresponding packet flow for the flow record of the flow records has a discrepancy with the updated network policy, output an indication of an error.

Abstract: A method for managing a plurality of network devices of a network includes determining, by one or more processors, a causality map for the plurality of network devices according to an intent. The method further includes receiving, by the one or more processors, an indication of a network service impact and determining, by the one or more processors, a relevant portion of the causality map based on the network service impact. The method further includes determining, by the one or more processors, one or more candidate root cause faults based on the relevant portion of the causality map and outputting, by the one or more processors, an indication of the one or more candidate root cause faults.

Abstract: Techniques are described for detecting that a client device physically connected to a network device is “stuck,” that is, the client device is not sending or receiving network packets with the network device. A network management system (NMS) receives current network statistics of ports of network devices with respect to client devices physically connected to the ports. The NMS identifies a candidate client device connected to a particular port of a particular network device for which the current network statistics indicate an issue. The NMS detects anomalous behavior of the candidate client device based on one or more features of the current network statistics, historical baseline statistics associated with the candidate client device, and peer statistics associated with one or more peer client devices of a same device type as the candidate client device. The NMS outputs a notification of the anomalous behavior.

Abstract: Techniques are disclosed for a network management system (NMS) that performs quality of service (QOS) monitoring and troubleshooting of user experience issues occurring outside of a network managed by the NMS using data obtained from third-party sources. For example, an NMS obtains third-party data of a third-party application server or third-party service provider server from a third-party monitoring vendor. The NMS identifies a user experience issue indicated by the third-party data and stitches the third-party data to network data received from network devices. The NMS determines a root cause or a remedial action of the user experience issue based at least on the network data received from the one or more network devices. The NMS generates a notification for presentation to an administrator device which identifies the root cause or the remedial action of the user experience issue.

Abstract: In some implementations, a heatsink assembly may include a heatsink that transfers heat from a pluggable module plugged into a frame, a clip coupling the heatsink to the frame and biasing the heatsink toward the pluggable module when the pluggable module is plugged into the frame, and an actuator plate that engages with the pluggable module as the pluggable module is plugged into the frame and thereby translates between an activated position and a deactivated position. When the actuator plate is in the activated position, the actuator plate may lift the heatsink away from the pluggable module, and, when the actuator plate is in the deactivated position, the actuator plate may permit the heatsink to engage the pluggable module. The actuator plate may translate from the activated position to the deactivated position by contacting the pluggable module as the pluggable module is plugged into the frame.

Abstract: An electrostatic discharge bag may include a bottom portion, and a front portion integrally connected to the bottom portion and including a first inside-out creased edge. The electrostatic bag may include a first side portion integrally connected to the bottom portion and the front portion and including a second inside-out creased edge and a first pair of outside-in creased edges, and a second side portion integrally connected to the bottom portion and the front portion and including a third inside-out creased edge and a second pair of outside-in creased edges. The first and second pairs of outside-in creased edges may enable the electrostatic discharge bag to collapse inward and downward toward the bottom portion. The electrostatic discharge bag may include a rear portion integrally connected to the bottom portion, the first side portion, and the second side portion and including a fourth inside-out creased edge.

Abstract: A network device may receive policy data identifying a first segment routing (SR) policy and a second SR policy. The first SR policy may be associated with a first path through a network and a first next hop, and the second SR policy may be associated with a second path through the network and a second next hop. The network device may advertise, to another device, reachability associated with the first next hop and the second next hop, and may receive, from the other device, a packet with a header. The network device may determine, from the header, data identifying the first next hop or the second next hop, without performing a lookup, and may cause the packet to be routed to a destination address, via the first path or the second path, based on the policy data associated with the first next hop or the second next hop.
