The present disclosure relates to a method and apparatus for processing sensor data, a computing device and a storage medium, which are used to solve the problem of inconsistency in sensor data streams transmitted to an algorithm module in the prior art. The method for processing the sensor data comprises: receiving a plurality of data streams to be processed, each data stream corresponding to a sensor, and each data stream comprising a data frame having a generation timestamp; correcting the generation timestamps of the data frames to acquire corrected timestamps; and determining, based on the corrected timestamps of the data frames and preset data transmission periods, a data frame to be transmitted in each data transmission period for each data stream.

This disclosure generally relate to a method and system for network policy simulation in a distributed computing system. The present technology relates techniques that enable simulation of a new network policy with regard to its effects on the network data flow. By enabling a simulation data flow that is parallel and independent from the regular data flow, the present technology can provide optimized network security management with improved efficiency.

Disclosed herein are systems, methods, and devices for time of arrival estimation in wireless systems and devices. Devices include a packet detector configured to identify a data packet included in a received signal having a symbol frequency. Devices also include a time stamping unit configured to generate an initial time stamp in response to the packet detector identifying the data packet. Devices further include an IQ capture unit configured to acquire a plurality of IQ samples representing phase features of the received signal. Devices additionally include a processing unit that includes one or more processors configured to generate an estimated time of arrival based on the initial time stamp and the plurality of IQ samples.

Methods for tracing a packet in a pipeline comprising a set of tables, in an SDN using OpenFlow. The packet comprises a trace bit, and is provided with a TTL value. A first network node indicates to a second network node to have each flow table decrement the TTL value by 1, based upon the trace bit. The first network node initially sets the TTL to be 1, and then sends the packet to a first table in the second network node. The first network node receives the packet, from another table in the set, and for every remaining table, and one table at a time: a) increments the TTL value by 1, and b) repeats the sending, and the receiving, until a last table is reached or a criterion is met. The first network node then indicates a route followed by the packet.

A communication control device stores reception data received from a network in any one of a plurality of reception queues to which different priorities have been given in advance to transfer the reception data to a main memory. The communication control device includes a reference table and a selection unit. In the reference table, at least one of a source address, a destination address, and an Ethernet frame type of the reception data to be stored is defined for at least one of the plurality of reception queues. The selection unit selects a reception queue in which the reception data is to be stored with reference to the reference table using at least one of the source address, the destination address, and the Ethernet frame type of the reception data.
