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. WebDec 22, 2024 · Congestion control in TCP is hobbled by two limitations. First, congestion can only be detected when there is buffer occupancy; this virtually guarantees some packet queueing when the network is loaded. ... Incast can occur if many senders simultaneously send unscheduled packets, but Homa’s RPC orientation enables a simple mitigation; see …
