    Abstract: Techniques, which may be embodied herein as systems, computing devices, methods, algorithms, software, code, computer readable media, or the like, are described herein for generating heatmap visualizations. A heatmap visualization can be a graphical representation of data where the coordinates of a cell in the visualization can be a key that describes a group of data represented by the cell. The colors of a heatmap may indicate information about the data represented by the cell (e.g., the amount of data in the cell). These cells can be rendered by calculating a per-pixel metric rate for each dataset in the heatmap visualization and mapping a dataset's rate onto pixels within the visualization that correspond to the dataset. After this mapping, the maximum rate within the visualization can be used to determine the visualization's colors and the cells can be rendered by coloring each pixel (e.g. pixel row) in its corresponding color.

  • Publication number: 20260270186
    Abstract: In one implementation, a device may obtain a Simple Two-way Active Measurement Protocol test packet that includes hop-by-hop data collected by the Simple Two-way Active Measurement Protocol test packet along its path. The device may determine whether the Simple Two-way Active Measurement Protocol test packet includes an instruction to reflect the hop-by-hop data back to an originating session sender. The device may copy, based on a determination that the Simple Two-way Active Measurement Protocol test packet includes the instruction, the hop-by-hop data into a type-length-value segment of a reply Simple Two-way Active Measurement Protocol test packet. The device may transmit the reply Simple Two-way Active Measurement Protocol test packet back to the originating session sender.

  • Patent number: 12730834
    Abstract: Embodiments are directed towards real time display of event records and extracted values based on at least one extraction rule, such as a regular expression. A user interface may be employed to enable a user to have an extraction rule automatically generate and/or to manually enter an extraction rule. The user may be enabled to manually edit a previously provided extraction rule, which may result in real time display of updated extracted values. The extraction rule may be utilized to extract values from each of a plurality of records, including event records of unstructured machine data. Statistics may be determined for each unique extracted value, and may be displayed to the user in real time. The user interface may also enable the user to select at least one unique extracted value to display those event records that include an extracted value that matches the selected value.

  • Patent number: 12732828
    Abstract: Various methods, systems, and/or processes are described herein that rely on a demand-based optimization logic that aims to improve wireless network performance. It involves selecting a floorplan, identifying access points associated with the floorplan, and assessing network demands of client devices within the area. Based on the demands, a demand-based power configuration is generated to adjust the output power of one or more access points. This configuration is transmitted to the identified access points to optimize network performance. By adjusting the power of access points to match the needs of client devices, more efficient and effective wireless network usage is realized.

  • Patent number: 12732871
    Abstract: Disclosed herein are systems, methods, and computer-readable media for minimizing pre-roaming resource reservations. In one aspect, it is determined that a client device connected to a first Access Point (AP) will roam, based on the determination, generating a list of APs that are roam candidates supportive of one or more resources needed by the client device, issuing a reservation request to the roam candidates, where the reservation request includes a timeout feature that persists the reservation at each AP on the list of APs for a set period of time, determining that a second AP within the list of APs will honor the reservation request, and automatically withdrawing the reservation request when the timeout feature has expired and the client device has not connected to the second AP, where the withdrawal of the reservation request frees up the one or more resources associated with the reservation request at each AP on the list of APs.

  • Patent number: 12732482
    Abstract: A first packet of a packet flow is received at a classifying network device. The first packet is forwarded from the classifying network device to a firewall network device. An indication that the packet flow is to be offloaded is received at the classifying network device. Data is stored at the classifying network device indicating that the packet flow is to be offloaded. A non-control packet of the packet flow is received at the classifying network device. A determination is made that the non-control packet belongs to the packet flow by comparing data contained in the non-control packet to the stored data. The non-control packet of the packet flow is directed to a processing entity in response to the determining. A control packet of the packet flow is received at the classifying network device. The control packet of the packet flow is directed to the firewall network device.

  • Patent number: 12732866
    Abstract: A system and method are provided for timing measurement in a wireless network to determine a location of a station (STA). A channel stability is determined for a channel between an initiating station (ISTA) and a first responding station (RSTA). A request for a first timing-measurement exchange is sent from the ISTA and the first RSTA. Parameters are negotiated for the first timing-measurement exchange based on the determined channel stability, and then the timing-measurement exchange is performed to generate a first set of times. This process is then repeated for another timing-measurement exchange between the ISTA and a second RSTA to generate a second set of times. A location of the ISTA is determined based on the first and the second sets of times.

  • Patent number: 12732448
    Abstract: Systems and techniques are provided for path tracing. For example, a process can include establishing a path tracing session associated with path tracing (PT) probe packets from a PT source node of an IPv6 network fabric. A PT probe packet can be received with a first IPv6 Destination Options Header with Path Tracing Option (DOH-PT) header that encodes path tracing information of the PT source node and indicates respective path tracing information for each PT midpoint node along a path from the PT source node to a PT sink node of the IPv6 network fabric. The received PT probe packet can be updated to include a second DOH-PT header that encodes path tracing information of the PT sink node. An updated PT probe packet includes the first and second DOH-PT headers and can be encapsulated with an additional IPv6 header corresponding to forwarding information of a collector node.

  • Patent number: 12732485
    Abstract: Methods are provided for a proxy infrastructure that serves as a bridge between an enterprise network and a computing machine of a user ensuring a chain of trust. The methods involve obtaining, from a client device, a request to navigate to one or more target devices of a remote enterprise network and locally authenticating the client device based on at least one of an identity of the client device and user credentials. The methods further involve generating a connection request for the client device to navigate to the one or more target devices based on the client device being locally authenticated and providing the connection request to a proxy service executing in the remote enterprise network. The proxy service authenticates an access to the one or more target devices based on device credentials while hiding the device credentials from the client device.
