Abstract: Embodiments described herein improve availability of a power plane in a network device by using a PoE manager that is separate from an operating system in the network device. For example, when the operating system (or a PoE application executing in the operating system) becomes unavailable, either because of failure or system upgrade, the PoE manager continues managing a power plane in the network device such that connected PDs continue to receive DC power. Stated differently, by using a PoE manager that is separate from the operating system, there is no fate sharing between the PoE manager and the operating system. If the operating system is unavailable, the PoE manager continues to provide the same power allotment to the PDs. As such, updates and failures which previously made the power plane unavailable no longer affect the power supplied to the PDs.

Abstract: Techniques are disclosed for generating a combined visual representation of subsets of devices associated with corresponding sub-networks of a private network, where at least two devices in corresponding sub-networks share a same private internet protocol (IP) address. The system generates a separate profile for each device using a combination of elements including at least (a) a private IP address corresponding to the device and (b) a network identifier corresponding to a sub-network associated with the device. These sub-networks and their constituent devices may be visually represented in corresponding user interface elements.

Abstract: Presenting, at a graphical user interface (GUI), device photos and risk categories associated with devices in a network is described. Data packets communicated in a network are detected. Based on the detected data packets, a set of devices in the network are determined. A set of device photos associated respectively with the set of devices are determined. A GUI concurrently presents the set of device photos to indicate the set of devices detected in the network. The set of devices may be filtered, sorted, and/or grouped based on various criteria. The GUI may present the device photos according to the filtering, sorting, and/or grouping. Additionally or alternatively, risk scores associated respectively with the set of devices are determined. The set of devices are categorized into respective risk categories based on the associated risk scores. A GUI concurrently presents a set of risk categories and information associated with each risk category.

Abstract: Techniques for identifying and mapping applications to devices in a network are disclosed. A system monitors data transmitted on a network to identify a plurality of data traffic patterns in the network. Based on the plurality of data traffic patterns, the system identifies a plurality of applications associated with respective subsets of the data, the plurality of applications including a first and a second application. The system determines that a particular network infrastructure element, among the plurality of network infrastructure elements, processes data associated with the first application. The system stores a mapping between the particular network infrastructure element and the first application.

Abstract: Techniques for generating and enforcing security policies for device clusters are disclosed. A security manager generates a plurality of clusters of devices for applying security policies. For each cluster of devices, the security manager trains a machine learning model to indicate whether a particular data flow associated with a device in the particular cluster of devices is allowed or denied. The security manager detects a data flow corresponding to a device. If the security manager determines that the device corresponds to a first cluster of devices, the security manager identifies a first trained machine learning model corresponding to the first cluster of devices. The security manager applies the first trained machine learning model to the first data flow to determine whether the first data flow is to be allowed or denied. The security manager allows or denies the first data flow based on the applying operation.

Abstract: Techniques for presenting, at a graphical user interface (GUI), a constellation view of communications associated with node groups of a network disclosed. A GUI presents icons arranged on concentric rings. Icons on one ring represent device groups. Icons on another ring represent address groups. Icons on another ring represent intranet groups. Each icon is selectable to request information about the communications of the corresponding node group. Connections are drawn between the selected icon and other icons to represent the communications. Each connection is selectable to request additional information regarding the communication.

Abstract: Techniques for determining a device profile and anomalous behavior associated with a device in a network are disclosed. Attribute values associated with a target device are determined based on data packets detected from a network. A subset of a set of classifiers associated with the available attribute values are selected. The attribute values are applied to the selected classifiers to determine a respective candidate device profile. A current device profile is determined for the target device based on the candidate device profiles. The current device profile indicates expected attribute values for the target device. Current attribute values are compared to the expected attribute values to determine whether there is any anomalous behavior associated with the target device.

Abstract: Embodiments described herein include a Power over Ethernet (PoE) enabled device that uses 2-event classification when allocating power to coupled powered devices (PDs). If the 2-event classification is successful, power sourcing equipment (PSE) on the PoE device allocates a maximum power allotment to the PD. Once powered on, the PD may determine it does not require the maximum power allotment and negotiate a reduction in the power allotted to the PD.

Abstract: Embodiments generally provide techniques for waking up a plurality of network devices from a power saving mode via layer 1 (L1) signaling. Embodiments include entering a power saving mode at a first network device, wherein logic for processing layer 2 and higher data is inactive during the power saving mode and receiving, while the first network device is in the power saving mode, a L1 bit stream from a second network device connected to the first network device. Additionally, embodiments include, upon determining that a predefined code is present within the received L1 bit stream, exiting the power saving mode at the first network device and transmitting a second L1 bit stream containing the predefined code to a third network device.
