Queuing and Loss

This animation illustrates queuing delay and packet loss.

Three different senders - inidcated by colors - send packets. The packets arrive and queue for service.
If the emission rate is higher than the transmission rate (both are slotted for better visualisation) a queue overflow will happen and according to the chosen method different packets will be dropped.
