Choosing the right protocol stack for an open and flexible remote unit

This paper presents some works made in the development of communications software for an embedded open core system. By using a Linux-based processor implemented on a FPGA, we are developing the appropriate software in order to implement a remote unit to be used in a telecontrol network. We present an analysis of the physical devices needed and a performance report of them. After that, we analyze the requirements of the telecontrol network and the possibility of re-using already implemented protocols in Linux instead of using standard telecontrol protocols.
