Abstract: In some embodiments, a device in a network receives a packet from a sender that is destined for a receiver. The device forms duplicate packets of the packet. The device assigns a sequence number to the duplicate packets based on an identity of the sender and on a flow identifier associated with the packet. The device sends the duplicate packets with the sequence number via different paths in the network towards the receiver.

Abstract: According to one or more embodiments of the disclosure, a supervisory networking device in an Ethernet ring obtains identity information for each of a plurality of other networking devices in the Ethernet ring. The supervisory networking device determines, based on the identity information, a relative position for each of the plurality of other networking devices in the Ethernet ring. The supervisory networking device generates, based on the relative position of each of the plurality of other networking devices in the Ethernet ring, a load balancing configuration for the Ethernet ring. The supervisory networking device implements the load balancing configuration in the Ethernet ring by blocking a first link of the supervisory networking device for a first subset of the plurality of other networking devices and a second link of the supervisory networking device for a second subset of the plurality of other networking devices.

Abstract: In one embodiment, a device in a wireless network receives telemetry data from a plurality of autonomous vehicles. The telemetry data is indicative of radio signal quality metrics experienced by the vehicles at a particular location over time. The device forms an array of wireless roaming thresholds by applying regression to the telemetry data. The device computes an optimum roaming threshold from the array of wireless roaming thresholds to be used by the vehicles when approaching the location. The device triggers, based on the computed optimum threshold, one or more of the autonomous vehicles to initiate access point roaming when approaching the particular location.

Abstract: Techniques for utilizing Software-Defined Field-Area Network (SD-FAN) controllers to receive a geographic location and transmission power of individual nodes and generate a geographic location topology of a Field-Area Network (FAN) to provide nodes with location-aware route paths for data transmission. One or more SD-FAN controller(s) may maintain a geographic location database to store the geographic location and transmission power of the individual nodes. Each node may utilize a Destination Address Object to advertise its geographic location and transmission power to the SD-FAN controller. The SD-FAN controller(s) may utilize the geographic location table to generate the geographic location topology of the FAN and determine a location-aware route path for optimized data transmission between nodes in the FAN.

Abstract: In one embodiment, a device in a mesh network joins a source-destination oriented partial directed acyclic graph (SDO-PDAG) between a source node and a destination node in the network. The device receives operations, administration and maintenance (OAM) packets flooded along reverse paths of the SDO-PDAG. The device determines, based on the received OAM packets, packet drop rate (PDR) capacities of different paths between the device and the destination node. The device replicates a data packet sent from the source node to the destination node along two or more of the paths between the device and the destination node, based on the determined PDR capacities of those paths.

Abstract: Techniques for accelerated Time series analysis (TSA) in a network are described. Packets from a first network flow at a network element, such as a switch or a router, are trapped using a hardware based TSA engine at the network element. The packets are then reduced into TSA tuples including TSA data points and stored into memory. A software based TSA module performs one or more TSA actions on the stored tuples, where the TSA actions produce analysis results used to determine network performance for the network and network based applications.
