METHOD AND DEVICE FOR CROSS-PACKET INSPECTION OF PROTOCOL BASED ON DEEP PACKET INSPECTION

摘要

Embodiments of the present invention provide a method and device for cross-packet inspection of a protocol based on deep packet inspection. The method for cross-packet inspection of a protocol based on deep packet inspection comprises: acquiring packets having different features in the same stream (101); determining whether each packet hits a certain rule (102); if the packet hits a certain rule, determining, according to the hit rule and the sequence of the packet, whether the stream hits a certain protocol (103). The embodiments of the present invention may perform cross-packet inspection of the protocol, be applicable to a multi-packet multi-rule application scenario, and have desired extensibility and flexibility.
