Abstract: Packet-processing circuitry including one or more flow caches whose contents are managed using a cache-entry replacement policy that is implemented based on one or more updatable counters maintained for each of the cache entries. In an example embodiment, the implemented policy enables the flow cache to effectively catch and keep elephant flows by giving to the caught elephant flows appropriate preference in terms of the cache dwell time, which can beneficially improve the overall cache-hit ratio and/or packet-processing throughput. Some embodiments can be used to implement an Open Virtual Switch (OVS). Some embodiments are advantageously capable of implementing the cache-entry replacement policy with very limited additional memory allocation.

Abstract: A method, apparatus, and computer program product are disclosed for determining, by a mobile wireless device, a likelihood that a first device ID of a target wireless device corresponds to a physical location of the first wireless device at a first measurement location, based on comparing a measured received signal strength of the target wireless device at the first and a second measurement locations and comparing the measured received signal strength of one or more other wireless devices at the first and second measurement locations. The mobile wireless device registers the first device ID of the target wireless device and associates the registered first device ID with the determined corresponding physical location of the target wireless device.

Abstract: An end-to-end telemetry system for a Remote Direct Memory Access (RDMA) communication network having multiple end-servers. The system includes an RDMA tracer for each end-server, one or more programmable data planes, and a telemetry collector. Each RDMA tracer extracts host-level telemetry information for one or more RDMA sessions associated with the corresponding end-server. Each programmable data plane extracts network-level telemetry information for one or more RDMA sessions associated with the programmable data plane. The telemetry collector (i) receives the host-level telemetry information from the RDMA tracers and the network-level telemetry information from the one or more programmable data planes and (ii) generates telemetry reports based on the host-level and network-level telemetry information. In some implementations, the system enables real-time monitoring of RDMA traffic at the RDMA protocol level granularity across all RDMA-enabled workloads for different use cases.

Abstract: System, method, and software for detecting anomalies in data generated by microservices. In one embodiment, an anomaly detector collects performance metrics for a microservice deployed in a data center for an application. The anomaly detector transforms the performance metrics into a time-series structured dataset for the microservice, and feeds the structured dataset to a machine learning system to determine whether an anomaly exists in the structured dataset based on an anomaly detection model. The anomaly detector performs an anomaly classification with the machine learning system based on an anomaly classification model and the structured dataset when an anomaly is detected in the structured dataset, and performs an action based on the anomaly classification.

Abstract: A CPU implements a virtual network function (VNF) associated with flow processing and can offload at least some of the flow processing to a hardware accelerator. A module (e.g., TOR switch), external to the software-based processor and the hardware accelerator, examines packet flows and determines (e.g., using a top-K elephant-flow-detection algorithm) which ones are more suitable for offloading from the software-based processor to the hardware accelerator than others. The external module communicates the relative suitability for offloading to the CPU using packet tags or out-of-band messaging, and the CPU uses the relative suitability to determine which flows to offload or onload. In some implementations, the CPU can instruct the external module to change the value of K used in the algorithm.
