Abstract: This paper presents a remote system call mechanism for expanding local operating system functions, and then discusses its structureand the key techniques. Using this mechanism and DSAG simulation platform, this paper implements a Linux application compatible environmentand the rfork/rpipe distributed functions. Finally, the author develops the test system and realizes the application.
