摘 要:
借鉴CCSDS文件传输协议和数据包交织的思想，提出了一种适合深空环境的基于交织技术的文件传输协议，接收端只需要接收到一定数量的数据包，就能够恢复出整个原始信息，无需或需要很少反馈确认信息。该协议能够减少文件传输时延，增大系统的吞吐量并保证通信的有效性。[著者文摘]

Abstract:
By adopting the ideas of CCSDS file delivery protocol （FDP）and packets interleaving, a new protocol based on interleaving technique and fountain codes theory is put forward. Under Such protocol, only a certain number of packet - data - units received by receiving end can the success of receiving whole file be guaranteed without any acknowledge or little information. Such protocol is able to shorten the file delivery delay, enhance throughput - ability and ensure the validity of communication compared with other protocols.[著者文摘]
