Problems solved by technology
[0003] In order to solve the current problem that the high-speed data received is directly written into the file, the hard disk reading and writing rate is reduced, the memory is insufficient, and the data cannot be received in real time and stored without frame loss. The invention discloses a high-speed FC data real-time reception without loss The frame storage method realizes real-time reception of high-speed data by directly reading and writing disk sectors

Embodiment Construction
[0026] The present invention can be explained in detail through the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.
[0027] A method for storing high-speed FC data in real time without losing frames, including application software receiving high-speed FC data from the bottom layer in real time, and realizing parsing the received FC data frames and storing them in local files. The implementation method of high-speed FC data real-time reception without frame loss storage is as follows:
[0028] 1) Select a logical partition or volume on the hard disk, such as selecting "E" disk, and allocate 400G space for E disk. E disk cannot store other files;
[0029] 2) Call the system function to create a disk file in the selected logical partition E disk, and lock the selected logical partition;
[0030] 3) Call the system function to move the pointer to the beginning of the disk...

A method for storing high-speed FC data in real time without losing frames, characterized in that: the high-speed FC data frames received in real time are correctly parsed and stored in a local file without frame loss, and a logical partition is selected on the hard disk for disk fan area read and write; create a disk file in the selected logical partition, and lock the selected logical partition; move the pointer to the disk sector to be written in the way of file operation, etc.; data recording adopts direct sector read and write technology; read The writing method abandons the commonly used file format, which greatly reduces the loss of addressing time caused by repeatedly querying the file allocation table and discontinuous sector records in the file management mode, thereby improving the data recording speed and realizing the speed of receiving data. No frame drops required.
Description
technical field [0001] The invention relates to a method for storing high-speed signal data in real time without losing frames, and belongs to the technical field of computer data processing. Background technique [0002] At present, for high-speed signal transmission equipment, when the signal transmission data volume is large, the speed is high, and the data is transmitted for a long time, in order to view the content of the transmitted high-speed data, the application software needs to realize the real-time reception and storage of high-speed data. The storage of data is generally by directly storing the received data in a local file. The storage process is as follows: figure 1 shown. However, when receiving and storing high-speed data for a long time, the rate of reading and writing files on the hard disk decreases, and the rate of receiving high-speed FC data far exceeds the rate of data storage to files, resulting in insufficient memory, and cannot realize real-time s...
