空间网络基于CFDP协议的并行多路径传输技术研究OA北大核心CSTPCD

This paper proposes a parallel multi-path transmission design based on the CFDP(CCSDS File Delivery Protocol),which expands the parallel transmission of files over multiple paths in space network file transfers.This design further enhances the efficiency of file transfer while maintaining compatibility with the original file transfer protocol.The design fully utilizes the characteristics of space network links and achieves the goal of parallel multi-path transmission by using load balancing algorithms for data scheduling to allocate file data to transmission paths reasonably.The simulation results demonstrate that compared with traditional CFDP transmission,this parallel multi-path transmission design fully utilizes multiple transmission paths,significantly reducing the file delivery time.
