WebThe meaning of INCAST is something added for good measure. WebSep 30, 2024 · For Ethernet switches, incast traffic may cause instantaneous burst congestion or even packet loss in the internal queue buffer of a switch. As a result, the application delay increases and the throughput decreases, which lowers the performance of distributed applications. WebSep 14, 2024 · Incast congestion happens when multiple sending servers under the same ToR switch send data to one receiver server simultaneously. This process is demonstrated in Fig. 2. Figure 2.
