Embodiment Construction

[0030] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0031] In order to solve the problem of poor processing efficiency when 3G network transmission is congested in the prior art, a network congestion control method is proposed according to one aspect of the present invention.

[0032] Such as figure 1 As shown, the specific workflow of the network congestion control method in the embodiment of the present invention is as follows:

[0033] Step 101: After the network transmission starts, use the slow start algorithm to control the network transmission rate, record each RTT value during the transmission process and calculate the average RTT value (RTT0).

[0034] RTT (Round-Trip Time) refers to the delay experienced by the sender sending data until the sender receives an...

Abstract

The invention discloses a network congestion control method and device. The method comprises the steps that whether long-time congestion control is carried out is determined; whether short-time congestion control is carried out is determined; and whether the MIMD congestion algorithm is used for transmission speed control is determined. According to the network congestion control method and device, RRT values are recorded and the average of RRT is calculated to distinguish short-time congestion from long-time congestion, rapid and effective transmission speed control is realized, and the present network resource of channels can be utilized more effectively.

Description

technical field [0001] The present invention relates to the technical field of multimedia network transmission under 3G network, in particular to a method and device for network congestion control. Background technique [0002] With the development of wireless networks, especially the acceleration of the practical process of 3G mobile communication standards, it has become an inevitable development trend that people mainly use mobile terminals to obtain various multimedia services. The key technology for the transmission of video streams in the wireless network is the quality of service (QoS, Quality of Services) guarantee. [0003] The current communication network is generally composed of wired network and wireless network. Wireless network transmission mainly encounters the following two problems: 1. Packet loss caused by node congestion; 2. Transmission errors in wireless network (fading, shadow influence) ) caused by packet loss or bit errors. In wireless networks, th...
