摘要: 提出了一种基于应用层ARQ的传输机制:BAATM(Transmission Mechanism Based on ARQ of the Application Layer)。基于BAATM,提出了一种数据封装:DDoIP(Data Directly over IP,数据直接IP封装)。DDoIP头部开销比TCP节约了20字节,比UDP节约了8字节;在传输数据量相同时,BAATM有效性比TCP提高了约30%,比TFTP提高了约50%。实验证明了BAATM的可行性。

Abstract: This paper proposes a new transmission mechanism based on ARQ of the application layer:BAATM.Based on BAATM,this paper proposes a new data encapsulation,DDoIP(Data Directly over IP).The overhead of DDoIP is 20 bytes less than that of TCP,and 8 bytes than that of UDP.Transmitting the same quantity of data,compared with TCP and TFTP,BAATM improved the performance about 30% and 50%.BAATM has been proved to be true.
