Problems solved by technology

[0003] In the existing passive proxy, it is mainly implemented by adding redirection rules to redirect the application data packets to the proxy program. However, in some practical applications, it is found that it may not be possible to distinguish the application to be accelerated from the proxy by relying on the redirection rule alone. After processing the data packets sent by the program, the data packets sent by the agent program will be redirected to the agent program again, causing the data packets to loop endlessly in the system

[0062] see image 3 As shown, the third embodiment of the present invention provides a data packet transmission system, the data packet transmission system includes a terminal device, an acceleration server, and a source station, and an application program and an agent program run on the local system of the terminal device.

[0063] Specifically, an application program is a program that provides users with specific business services, such as browsers, music and video services, and other functional service programs, and users obtain corresponding services by operating these application programs. The application program receives user operations and sends corresponding request data packets, which will pass through the proxy program and the local system, and finally be sent to the acceleration server or origin station for back-to-source response to user requests.

[0064] The proxy program processes the request data packets sent by the application programs, so that the request dat...

Abstract

The invention discloses a data packet transmission method. The method comprises the steps that: an agent program receives request data packets through a monitoring port, sets labels for the request data packets, and then, sends the request data packets with the labels; a local system receives the request data packets sent by the agent program and an application program, matches the labels in the request data packets, directly forwards the request data packets if the labels are successfully matched, and redirects the request data packets to the monitoring port of the agent program if the labels are failed to match; label setting of the data packets sent by the agent program is carried out; therefore, the local system can distinguish the request data packets from the application and the agent according to the labels; furthermore, corresponding operation is carried out; and thus, endless loop of the data packets in local can be avoided. The invention further discloses a data packet transmission system.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a data packet transmission method and system. Background technique [0002] With the continuous development of Internet technology, various applications have sprung up densely. In order to provide a better user experience, network acceleration services for applications have also emerged. Taking Android application proxy acceleration as an example, it can be divided into active proxy and passive proxy. Active proxy is when the application initiates a network request. Active agent acceleration, passive agent, also known as local agent, is to intercept specific request data packets to the local acceleration service program through certain means at the system level, and then the local agent program will perform corresponding acceleration control and then retransmit the data packets. send out. [0003] In the existing passive proxy, it is mainly implemented by adding redirection ru...
