Congestion occurs when machines send too many packets to a network too quickly from the transport layer. . Performance will become degraded as packets are dropped and lost.. Congestion Control. If the transport entities on many machines send too many packets into the network too quickly, the network will become congested, with performance degraded as the packets are delayed and lost..
