Abstract
A method, a device, and a system for network interception are provided. The method for network interception includes the following steps. A matching rule obtained by parsing an interception policy. Received data are selected by adopting a deep packet inspection (DPI) according to the matching rule so as to obtain an interception result, in which the received data are obtained by adopting data preprocessing to filter packet data according to a service customizing rule obtained by parsing the interception policy. The system for network interception includes a service probe server (SPS) and a service analyze server (SAS). Thus, various packet data services transmitted over an Internet protocol (IP) network can be intercepted.
