Research on the Improved Method of UDT Protocal
Di Zhang, XinDi Guan, Ren Zhihong · 2021
In order to overcome the problem of the low rate of high-performance data transmission protocol UDT in China Telecom network transmission, this paper proposes an improved method. Based on the verification of the data transmission rate of UDT protocol in China Telecom network, the paper proposes The SACK mechanism is used to cope with the problem of repeatedly sending data packets in the fast retransmission mechanism. In the slow start phase of the congestion control link, it solves the problem of speed reduction and misjudgment caused by packet loss. This method adds a small amount of control packet information. The data transmission rate of the improved UDT protocol between the three cities has been significantly improved.
