Abstract

The embodiment of the invention provides a data transmission management and control method and apparatus. The method is applied to a data transmission system comprising a transmitting end device and areceiving end device which communicate with each other. The method achieves effects of simultaneously weakening various network fluctuations by using a combination of three single network fluctuationweakening measures comprising packet loss retransmission, FEC recovery data and jitter buffer receiving data and reasonably distributing respective bandwidths of a first channel, a second channel anda third channel to ensure that each channel can transmit data with a proper data volume and a proper transmission quantity as far as possible, and improving the data transmission quality. The first channel is used for transmitting an initially transmitted data packet; the second channel is used for transmitting an FEC recovery packet; and the third channel is used for retransmitting a data packet.

Description

technical field [0001] The present application relates to the technical field of data packet transmission, and in particular, to a data transmission control method and device. Background technique [0002] With the continuous development of science and technology, network communication technology has also been rapidly improved, and data packet transmission technology is an important part of network communication technology. However, when data packet transmission technology is applied to real-time transmission scenarios, network fluctuations that affect data transmission quality, such as network congestion, packet loss, freeze, and high delay, usually occur due to the constraints of network bandwidth and hardware facilities of transmission equipment. . Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a data transmission management and control method and device, th...
