Problem definition

The goal of the semester project was to realise a relay for a switch fabric control that interconnects the backends of the signaling protocol engine. The internal signaling protocol as defined in ftp://lrcftp.epfl.ch/pub/linux/atm/docs/isp_0.2.tar.gz is used. A state machine had to be developped and implemented.
