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. Webheavy Incast over TCP, and 43.6% and 11.7% over Incast congestion Control for TCP (ICTCP). I. INTRODUCTION In datacenter networks, it is known that the many-to-one traffic pattern will also introduce severe TCP Incast Congestion problem in the high-bandwidth, low-latency cloud datacenter networks [8], [9].
