Abstract

The embodiment of the invention discloses a message processing method and device. The method comprises the following steps of: receiving three-time TCP (Transmission Control Protocol) handshake messages of a data stream and performing negotiation processing; receiving a data message of the data stream and carrying out application layer protocol identification on the data stream so as to judge an application layer protocol corresponding to the data stream according to the data message; judging whether the data stream needs mirroring or steering processing according to the application layer protocol; if not, not establishing a TCP effective session table entry on preset third-party equipment; if so, performing mirroring or steering processing on the data stream. With the method and the device, the resource loss of DPI (Data Processing Installation) can be reduced.

Description

technical field [0001] The invention relates to message processing technology, in particular to a message processing method and device. Background technique [0002] Packet mirroring technology means that after a device on the network receives a packet, it judges whether the packet conforms to a certain preset rule, copies the packet that conforms to the preset rule, and then transfers the packet from the designated physical port. The technology of message forwarding is described. At present, network devices such as switches and routers have this function. The switch supports port-based packet mirroring, and the router supports packet mirroring based on the access control list (ACL). Such as figure 1 As shown, a flow monitoring device (DPI) device is given a process of message mirroring processing. When the DPI device receives the message, if the message meets certain rules, such as the message belongs to the hyperfile transfer protocol (HTTP ) protocol, the message will ...
