基于Tsunami协议的干涉测量数据实时传输

sunami is a reliable UDP-based application-level transmission protocol. A requirement of the real-time transmission for interferometry data was introduced, and the congestion control mechanism based on the error-rate feedback applied in Tsunami was analyzed. A retransmission buffer was proposed to improve the retransmission strategy and the mechanism of packet sending of Tsunami, which is implemented in the real-time transmission of the interferometry data. Moreover, the relationship between the extra delay and the transmission rate control was deducted. Finally, a real-time data transmission test is conducted on a 622Mbps link, which shows that Tsunami can achieve much higher bandwidth utilization than that of the TCP protocol with a high bandwidth-delay product.
