Abstract: Examples described herein relate to a driver that is to: determine a configuration of a packet processing pipeline of a network interface device to perform an instruction set written in a domain specific language (DSL) for the packet processing pipeline based on emulation or analysis of a parser of the packet processing pipeline and provide the configuration to the packet processing pipeline of the network interface device to specify operations of the packet processing pipeline of the network interface device.

Abstract: The present invention provides a method for processing a filter to obtain a calibration dust filter, and a method for off-site calibration using the calibration dust filter. In the present invention, a batch of filters that meets specific requirements is screened out as the basal filters, and then the basal filters are processed in an actual environment to obtain the calibration dust filters. The counted number of beta particles is measured before and after sampling, and then a correction factor K is inversely inferred. The beta attenuation suspended particulate analyzer is corrected using the correction factor K.
