单向链路下高可靠数据传输方法
Method of high reliable data transmission over unidirectional link
摘要
Abstract
An adaptive coding method based on the maximum transmission rate was proposed to a‐chieve high reliability of data transmission in unidirectional link network .First the correlation be‐tween send rate and packet loss rate was utilized under unidirectional link ,and then the influence of redundant code for packet loss rate was studied when sending rate shall not exceed the maximum rate . Namely one‐way control mechanism was adopted based on ErasurseCode algorithm under low packet loss rate to adjust coding strategy based on maximum rate ,and establish redundancy check betw een the transmissions of message .Using maximum safe rate of link to transfer redundancy coding infor‐mation and get back the lost packets as high as possible .T he experimental results show that the pro‐posed adaptive coding method can effectively reduce the packet loss rate meanw hile guarantee low packet loss rate ,and further improve the fault tolerance of one‐way transmission ,realize the high reli‐ability of unidirectional data transmission .关键词
