Design and Implementation of the File Transfer System YHFTS in Yinhe High-Speed Network

The file transfer system YHFTS in the Yinhe high speed network implements ISO FTAM protocol,and provides remote file transfer,file operation,job submission,spooling print and so on for users.This paper introduces FTAM protocol,gives the implementation model of YHFTS,reco- unts the block structure of the file access utility（FAU）and the file access listener（FAL）,and the way they work,and describes the implementation method of the FTAM protocol machine and the direct coding/decoding model.
