However, COTS switches may

Reconciling the use of ordinary switches with the needs of real-time communication requires an adequate overlay protocol. In this paper we focus on using a Master-Slave technique to overcome the COTS switch limitations in real-time applications, namely the FTT-SE protocol. We extend the protocol for large scale networks and we present the worst-case delay analysis using the Network Calculus formalism for such a network. Moreover, we assess the end-to-end delay of traffic with simulation.
