How is bandwidth managed in an unmanaged network switch?
Suppose that port 1 is connected to a a very busy server. If suddenly machines connected to ports 2, 3 and 4 decide to send a massive amount of packets (in an extreme scenario: at maximum theoretical throughput) to the server in port 1, how will the switch handle this?
Will the switch perform any sort of flow control, ensuring that each sending port gets a fair share of the available bandwidth to port 1, or will they simply be served in a "first come, first served" manner (obviously, dropping packets as necessary)?
