Abstract: In one implementation, a device obtains a natural language-based description of a network via a user interface. The device generates, based on the natural language-based description, network configuration parameters for the network using a generative model. The device conducts a simulation of traffic in the network using the network configuration parameters, to obtain telemetry data. The device uses the telemetry data to train a machine learning model to perform network analytics.

Abstract: In one aspect, a system includes a station device configured to transmit a signal; multiple access point devices in connection with the station device, the multiple access point devices configured to receive the signal transmitted from the station device, wherein the multiple access point devices are configured to convert the signal into a measurable form; and a processing unit operably connected to the multiple access point devices. The processing unit is configured to, for each subcarrier within the signal received by the multiple access point devices, determine a measurement of channel state information including an overall shape of the signal; determine a magnitude distance for each subcarrier; and determine a location of the station device based on a fit of the magnitude distance to a model, wherein the model is based on an environment with one or more obstacles causing an obscuration of the signal.

Abstract: Symmetric networking techniques disclosed herein can be applied by gateway routers in cloud networks. The techniques can ensure that both outbound traffic received at a cloud from a branch device and return traffic directed from the cloud back to the branch device are processed by a same gateway router. The gateway router can use network address translation to insert IP addresses from an inside pool and an outside pool assigned to the router.

Abstract: This disclosure describes various methods, systems, and devices related to identifying path changes of data flows in a network. An example method includes receiving, at a node, a packet including a first signature. The method further includes generating a second signature by inputting the first signature and one or more node details into a hash function. The method includes replacing the first signature with the second signature in the packet. The packet including the second value is forwarded by the node.

A device may utilize one or more error patterns associated with the network device to retrieve one or more symbol errors from the one or more error patterns. The device can determine an error threshold for a segment based on a predefined Bit Error Rate (BER) level for the segment. The device may generate a performance metric for the segment based on the error threshold and the retrieved symbol errors. The device can generate a receiver performance metric based on performance metrics of segments. The device may determine a Code Error Ratio (CER) and can predict a Frame Loss ratio (FLR) associated with the network device based on the CER.
