WebJan 1, 2015 · Impairments such as TCP Incast, TCP Outcast, Buffer pressure, Queue build-up and pseudo-congestion effect severely degrade the performance of traditional TCP variants in DCNs. With cloud computing becoming an important part of the forseeable future, it is extremely crucial to eliminate these impairments. 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.
