Abstract

This specification provides a message forwarding method, device and gateway equipment, relating to the field of communication equipment. A message forwarding method, comprising: receiving a data flow message sent by a logic chip; when it is determined that the data flow message is the first message, generating a session entry for the data flow, and sending the session entry to the logic chip ; When it is determined that the data flow message is not the first message, the data flow message is carried out in-depth message detection DPI processing, after determining that the operation corresponding to the matched application layer security policy is release, the first identification is placed as a match state, and set the second identifier in the issued session entry to the effective state, so that the logic chip forwards the data flow message according to the issued session entry. Through the above method, the forwarding speed of the data flow of the gateway device can be increased when the application layer security policy control is activated.

Description

technical field [0001] This specification relates to the field of communication technologies, and in particular, to a message forwarding method, apparatus, and gateway device. Background technique [0002] With the development of the network, when the gateway device forwards the packets, there are two methods: software forwarding and hardware forwarding. During software forwarding, the processor executes software algorithms to process and forward packets; during hardware forwarding, FPGA (Field Programmable Gate Array, Field Programmable Gate Array) or ASIC (Application-Specific Integrated Circuit, Application Specific Integrated Circuit) and other logic chips process and forward packets. More functions can be achieved through software forwarding, while higher forwarding speed can be achieved through hardware forwarding. [0003] Due to the user's requirement for network security, on the basis of identifying the quintuple of the packet and executing the security policy, it...
