分析RUDP和UDT数据传输协议的优缺点,对拥塞控制机制进行改进:在服务器端添加拥塞控制算法,根据反馈信息被动触发,在客户机端实行主动拥塞避免机制,从而提高传输效率和可靠性,在延时抖动和吞吐量方面也有所改进. This paper analyzes the advantages and disadvantages of RUDP and UDT data transmission protocol and improves the congestion control mechanism by adding a congestion control algorithm on the server side and passively triggering according to the feedback information to implement an active congestion avoidance mechanism at the client end so as to improve transmission efficiency and reliability, There are also improvements in latency jitter and throughput.
