Abstract

The invention provides a method for inserting and unloading a transmission control protocol (TCP) proxy and service gateway equipment. The method comprises the following steps of: during establishment of TCP connection, forwarding a TCP connection establishing message between a TCP client and a TCP server via an L3 layer, and recording option information and serial number information of the TCP connection establishing message; after the TCP connection is established, judging the received massage according to an agent policy; forwarding the message not needing the agent determined according to the agent policy via the L3 layer, and updating the recorded serial number information according to the serial number information of the received message; for the message needing the agent determined according to the agent policy, generating a client pseudo-socket and a server pseudo-socket according to the recorded option information and serial number information; and terminating the received message by adopting the client pseudo-socket and the service end pseudo-socket, and processing the terminated message via an L7 layer, and forwarding the processed message. By the method, the system performance can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a transmission control protocol (Transmission Control Protocol, TCP for short) proxy insertion and unloading method and a service gateway device. Background technique [0002] In order to solve the challenges faced by Mobile Broadband (MBB) operations, service gateway devices are usually deployed at the gateway connecting mobile terminals to the mobile Internet to achieve refined data service control and management. In order to achieve fine-grained data service control and management, usually the service gateway device needs to analyze the content of layer 7 (L7 layer) data packets, and perform related processing according to its content and related attributes, such as content adaptation, content enhancement, anti-virus, network acceleration . Since basically all network services are based on TCP, in order to realize the above-mentioned rel...
