Network is Ethernet 100BASE-TX with switch in the middle. 8 ports.
At what point should I start to worry about QoS. Right now I do not go above 15 Mbps as being the total offered node. i.e. Worst case 15 Mbps offered to one port and clients at say two ports 7.5 Mbps at each. 50% VoIP and 20% TCP and 30% UDP.
I think I do not need QoS yet, but is there a norm or some accepted industry practice say when you need to start worrying. For the UDP and VOIP I have no reliability built in.
Note: The switch is supposed to be 100BASE-T standard.
