WebJul 18, 2024 · Incast congestion is a catastrophic loss in throughput that occurs when the number of senders communicates with a single receiver by sending data increases beyond the ability of an Ethernet switch to buffer packets. It leads to severe packet loss and consequently frequent TCP timeouts and thereby reduces the performance of TCP. WebJun 1, 2014 · Congestion occurs when synchronized servers under the same Gigabit Ethernet switch simultaneously send data to one receiver in parallel .Only after all connection have finished the data transmission can the next round be issued. Thus these connections are called barrier-synchronised.
