Problems solved by technology

However, the physical properties of wireless links and wired links are quite different. Wireless links are affected by environmental interference and are more prone to packet loss, which does not entirely depend on whether the network is congested. Therefore, the TCP protocol cannot adapt well In the wireless link environment, the disadvantage is that the server often needs to use an extremely slow-down processing method to send downlink data to the client on the mobile terminal, and usually, the server initiates a timeout retransmission response to the client. slower

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] see figure 1 , a method for accelerating data transmission is provided in an embodiment. This method can be applied in the scenario where the "acceleration" server sends downlink data to the client in the wireless network. The method includes processes:

[0040] Step 102, the acceleration device listens to the handshake signal from the client requesting the server to establish a TCP connection.

[0041] Specifically, the acceleration device is deployed at the interface between the wireless network and the wired network, the client is a client in the wireless network, and the server is a s...

Abstract

The invention discloses a method and device for accelerating data transmission. The method includes the steps that an accelerator monitors a handshake signal indicating that a client side requests establishment of TCP connection from a server side; the accelerator acts as a proxy to conduct TCP connection, establishes wireless connection with the client side, establishes wired connection with the server side and determines a first send window and a second send window respectively, wherein the first send window transmits data to the client side through a wireless network and the second send window transmits data to the server side through a wired network; according to the size of the second send window, downlink data sent by the server side are received and cached by the accelerator through the wired network; according to the first send window, the downlink data is forwarded by the accelerator through the wireless network to the client side. By the adoption of the technical scheme, the condition that the server side sends the downlink data to a mobile terminal in the wireless network in a decelerating mode can be avoided.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a data transmission acceleration method and device. Background technique [0002] With the application of mobile terminals becoming more and more popular, the demand for mobile terminals for office and entertainment is increasing. As an important way to realize mobile office and entertainment, wireless networks have penetrated into all aspects of our lives. For example, mobile terminals can The network is connected to AP (Access Point, wireless access point), AC (Access Controller, wireless controller) and other devices, and then AP, AC, etc. are connected to the server through a wired network, so that the server can send The mobile terminal sends data downlink to realize office and entertainment on the mobile terminal. [0003] In the process of data interaction between the client and the server, network protocols are bound to be involved. TCP (Transmission control P...
