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. The scenario of incast congestion in data-center networks, where multiple TCP senders transmit data to the same receiver under the same ToR switch. Webincast congestion happens. For example, DT always keeps a specific amounts of buffer reserved for other inactive ports, while a port that experiences incast might need it. To further evaluate DT’s perfor-mance, we simulated a datacenter network using reported numbers in previous studies (e.g., [52] and [64]) to measure the performance
