ETHERNET DATA STREAM RECORDING METHOD FOR HIGH SPEED DATA ACQUISITION SYSTEM

摘要

The present invention belongs to the fields of high speed data acquisition and network data processing, and in particular relates to an Ethernet data stream recording method and system for a high speed data acquisition system, and a device, aiming to solve the problems of low CPU utilization, poor system compatibility, packaging and deployment difficulty, and low system transmission reliability in the existing high speed data acquisition. The present system method comprises: after a Linux operating system is started, isolating a set number of CPU cores; uninstalling a kernel mode network card driver of the operating system, creating a huge page memory pool, allocating a corresponding data receiving buffer pool and lock-free FIFO buffer to each 10 Gigabit network card, and initializing a PCIE register of each 10 Gigabit network card to enable same to enter an acquisition state; and continuously receiving and disk recording data packets acquired by each 10 Gigabit network card in a user-mode polling drive manner. The present invention improves the CPU utilization, system compatibility and transmission reliability, and reduces the difficulty in packaging and deployment.
