Research of Multimedia Data Transmission Based on UDP

摘要：

The article focuses on the research of a reliable data transmission extension protocol — UDT based on UDP, the related implementation method and transmission control method of multimedia data realtime and reliable transmission, the improvement to algorithm of its related methods in specific applications; as well as the improvement to AIMD (Additive Increase and Multiplicative Decrease) congestion controlling algorithm, proposing DAIMD congestion controlling algorithm; the sending rate increment is changed from the constant quantity to the variable quantity which continuously reduces with the continuous increase of the sending rates, so it not only makes a more rational use of limited network bandwidth, also reduces the larger oscillation in the network data transmission; the improvement of validation mechanisms, propose validation mechanisms based on the combination of time and data packets numbers, and improve the efficiency of data transmission.
