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, and at least one additional segment is an instruction for handling the error message. The network device sends the encapsulated error message to the remote server based on the first segment of the segment routing header.

Abstract: In one embodiment, a method includes receiving flight path data regarding the presence of an unmanned aerial vehicle (UAV) at a location at a future time, detecting the presence of the UAV at the location at the future time, determining radio identity data of the UAV using a radio mode of identification, determining optical identity data of the UAV using an optical mode of identification, and certifying the UAV based on a comparison of the radio identity data and the optical identity data to the flight path data.

Abstract: Systems, methods, and computer-readable media for orchestrating data center resources and user access to data. In some examples, a system can determine, at a first time, that a user will need, at a second time, access to data stored at a first location, from a second location. The system can identify a node which is capable of storing the data and accessible by a device from the second location. The system can also determine a first service parameter associated with a network connection between the device and the first location and a second service parameter associated with a network connection between the device and the node. When the second service parameter has a higher quality than the first service parameter, the system can migrate the data from the first location to the node so the device has access to the data from the second location through the node.

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.

Abstract: Presented herein are methods and systems that facilitate data plane signaling of a packet as a candidate for capture at various network nodes within an IPv6 network. The signaling occurs in-band, via the data plane—that is, a capture or interrogation signal is embedded within the respective packet (e.g., in the packet header) 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 IPv6 network are signaled to capture or further inspect the packet for capture.

Abstract: Disclosed is a router (and method) for virtualizing a control plane of the router without redundancy. The router can include a processor, a data plane, a control plane, and a computer-readable storage medium having stored therein instructions which, when executed by the processor, cause the processor to request, a cloud service to instantiate a virtual instance of the control plane, receive a confirmation of instantiation of the virtual instance, transfer to the virtual instance of the control plane, an active state of the control plane, perform offline services (e.g., configuration change, operating system update, or firmware upgrade, etc.) and in response to completion of the offline services, receive the active state.

Abstract: In one embodiment, an autonomous vehicle receives a location of a fiber optic cable repeater of a fiber optic cable. The autonomous vehicle navigates the vehicle to the location of the fiber optic cable repeater and interfaces an optical time domain reflectometer (OTDR) of the autonomous vehicle with an OTDR port of the fiber optic cable repeater. The autonomous vehicle performs OTDR measuring of the fiber optic cable via the OTDR port of the fiber optic cable repeater, and sends a result of the OTDR measuring of the fiber optic cable to a supervisory device.

Abstract: In one embodiment, a device in a network joins a fog-based malware defense cluster comprising one or more peer devices. The device and each peer device in the cluster are configured to execute a different set of local malware scanners. The device receives a file flagged as suspicious by a node in the network associated with the device. The device determines whether the local malware scanners of the device are able to scan the file. The device sends an assessment request to one or more of the peer devices in the malware defense cluster, in response to determining that the local malware scanners of the device are unable to scan the file.

Abstract: Presented herein are service-function chaining techniques that enable data plane signaling of a packet as a candidate for capture at various network nodes along a service function path of a service function chain. That is, a capture signal is embedded within the respective packet that carries a user traffic. The signaling occurs in-band, via the data plane, such that classification of the packet for capture beneficially occurs, at the ingress node of the network, once to which subsequent network nodes along a service function path are signaled to capture or further inspect the packet for capture. Service function chaining treats service functions as resources with associated attributes available for scheduled consumption to which selective traffic are steered according to a policy construct to the requisite network-service resources.
