In this solution there are still some limitations which are the important obstacles obtaining timeliness in the network. The FTT-SE protocol which is a technique based on the master/slave and FTT methods was proposed to overcome the mentioned limitations. However, the FTT-SE protocol has been investigated for a small network architecture. In this work we propose a solution that extends the FTT-SE protocol while keeping the real-time behavior of the network.
