Seamlessly connected kernel data packet acquisition technology

Abstract

The invention relates to a seamlessly connected kernel data packet acquisition technology. The technology comprises the following operation steps: firstly, driving is performed on a kernel registration network intermediate layer; secondly, data packets are cached in network intermediate layer driving in a blocked way, blocked data is stored in a queue, and each data cache is set to be 2M; thirdly, when a data traffic peak value exceeds a data packet disc writing speed, a data storage queue can automatically apply memory from a system, so as to meet the storage requirements, when the data traffic peak value is recovered, data cache blocks used for a long time can be released, and the data storage queue can be automatically adjusted according to data traffic; fourthly, when a thread is started in a kernel to read blocked data in a cache queue, and when the quantity exceeds the designated data packet quantity, the blocked data cache is written in disc files in order; fifthly, the blocked data is written in a disc according to a PCAP file format.

Description

technical field [0001] The invention relates to seamless kernel data packet capture and belongs to the technical field of computer applications. Background technique [0002] With the rapid development and expansion of computer network technology, especially the rapid development of the Internet in recent years, society has entered an era of information explosion, and the world has become smaller due to the network. People use various technologies and tools to make communication break through the limitation of space. . Global network interconnection has brought convenience to people's life and work, and people are enjoying the better life brought by network technology. But at the same time, some criminals use the loopholes of the network to illegally invade other people's host systems, and some use the network to steal other people's personal information, such as online bank account passwords, etc., posing a major threat to the safety of other people's property.
