A system and realization method for high speed capture and quick storage of IPv6 data

The invention relates to a system for picking up IPv6 data at high speed and quickly storing, and a relative method. Wherein, it comprises an initialization module; an IPv6 data picking up module for real-time picking up the IPv4/v6 dataflow through detecting interface, while the picked data can be used in following protocol analysis; IPv6 protocol analyze module for processing the picked IPc4/v6 data to match the picked data from outer to inner with variable protocols, to analyze the protocols of all layers, to be stored in memory unit set for different protocols. The invention uses bidirectional linkage list technique to quickly write and discompose the picked IPv6/v4 data pack in memory queue. And it uses multi-process technique to pick and record high-speed data at IPv6/v4 network, to be analyzed and stored.
