In this paper we analyzed how a frame size type, period and number of virtual links affect bandwidth utilization in deterministic networks. For services which combine avionics applications and consumer electronics, such as In-flight entertainment, this analysis is very important. We analyzed one topology of TTEthernet deterministic network, and influence of the TT, RC, and synchronization traffic classes to total bandwidth utilization. Bandwidth that is not used for this traffic classes, can be exploited for consumer electronics applications traffic.
