Abstract: Presented herein are segment-routing methods and systems that facilitate data plane signaling of a packet as a candidate for capture at various network nodes within a segment routing (SR) network. The signaling occurs in-band, via the data plane—that is, a capture or interrogation signal is embedded within the respective packet that carries a user traffic. The signaling is inserted, preferably when the packet is classified, e.g., at the ingress node of the network, to which subsequent network nodes with the SR network are signaled to capture or further inspect the packet for capture.

Abstract: A network device receives a data packet including a source address and a destination address. The network device drops the data packet before it reaches the destination address and generates an error message indicating that the data packet has been dropped. The network device encapsulates the error message with a segment routing header comprising a list of segments. The first segment of the list of segments in the segment routing header identifies a remote server. The network device sends the encapsulated error message to the remote server based on the first segment of the segment routing header.

Abstract: Various implementations disclosed herein enable improved allocation of fog node resources, which supports performance driven partitioning of competing client applications. In various implementations, methods are performed by a fog orchestrator configured to determine allocations of fog resources for competing client applications and partition the competing client applications based on the fog resource allocations. Methods include receiving reservation priority values (RPVs) associated with a plurality of client applications competing for a contested fog node resource, transmitting, to a subset of client devices, a request to provide updated RPVs, and awarding the contested fog node resource to one of the plurality of client applications based on the received RPVs and any updated RPVs. In various implementations, methods also include determining, for each of the plurality of client applications, a respective mapping for a respective plurality of separable components of the client application based on the awarded contested fog node resource.

Abstract: A network device may connect to a smart-enabled network. Once connected, the network device may receive a network address for a network management server (NMS). Having the network address for the NMS, the network device may generate a vCard comprising the attributes necessary for registering with the NMS. The network device may then communicate the vCard to the NMS. The NMS may then be configured to identify, register, and add the network device to a directory.

Abstract: In one embodiment, an intermediate node, of a multi-stage process path through a computer network, receives a workload message with an associated latency budget to complete the multi-stage process at a final stage device. In response, the intermediate node determines a current latency from an initial stage device for the workload message to the receiving of the workload message, and also determines a remaining portion of the latency budget based on the current latency. In response to the remaining portion of the latency budget being less than expected at the intermediate node, the intermediate node may perform one or more latency-reducing actions, and then transmits the workload message toward the final stage device.

Abstract: In one embodiment, a device in a network receives a set of sensor data from a plurality of sensors deployed in a location. The device determines a physical layout for furnishings in the location based on the received set of sensor data. One or more of the furnishings is equipped with one or more actuators configured to move the equipped furnishing in one or more directions. The device generates an instruction for the one or more actuators of a particular one of the furnishings based on the determined physical layout for the furnishings. The device sends the instruction to the one or more actuators of the particular furnishing, to implement the determined physical layout.

Abstract: Various implementations disclosed herein enable transforming mutable wireless coverage areas using network coverage vehicles (NVCs) that are orchestrated by a network coverage controller. In various implementations, the method includes receiving coverage area performance characterization values from NCVs configured to provide a plurality of mutable wireless coverage areas. In various implementations, an arrangement of the mutable wireless coverage areas mutably defines the service area, which changes in accordance with changes to the arrangement of the mutable wireless coverage areas. In various implementations, the method also includes determining NCV operation adjustments for some of the NCVs based on the received coverage area performance characterization values in accordance with a service performance metric; and, altering an arrangement of one or more of the plurality of mutable wireless coverage areas within the service area by providing the NCV operation adjustments to some of the NCVs.

Abstract: In one embodiment, a first wireless unmanned aerial vehicle (UAV)-locating signal is transmitted by a wireless network access point in a network based on a first UAV-locating mode selected from a plurality of UAV-locating modes. The wireless network access point receives a wireless signal in response to the first transmitted UAV-locating signal, the wireless signal indicative of a location of an airborne UAV, and causes the determination of the location of the airborne UAV based on the received wireless signal. The wireless network access point transmits a second wireless UAV-locating signal based on a second UAV-locating mode selected from the plurality of UAV-locating modes. The selected UAV-locating modes control an emission pattern of an antenna of the wireless network access point.

Abstract: Disclosed are systems, methods and non-transitory computer-readable mediums for dynamically presenting and updating a directed time graph displayed in a graphical user interface. In some examples, the method can include displaying a suggested path within a graphical user interface on a computer screen, the suggested path can include outstanding issues of elements of a network. The displaying the suggested path can include determining based on one or more factors an efficient ordering of the outstanding issues and ordering the outstanding issues based on the one or more factors. The method can also include monitoring, at regular intervals, updates to the one or more outstanding issues and automatically updating the suggested path, by a processor, based on the updates to the one or more outstanding issues.
