With the rapid development of the network technology and the increase of the network band width,network security is be-coming more and more important.As a necessary method,capture and monitoring of network packet has been widely used in real life.It is proved that filter model is subject to the efficiency of network packet capture and traditional data analyzing methods have no mathe-matical model as base.After network packet transition and capture mechanism is studied,two different predicate filter model are analyzed in detail and efficiency is compared with a result that CFG model is better than tree model in general.
