Figure 1(a) shows that an Incast traffic with the line-rate as the initial rate will cause a queue length peak up to 340KB at the switch. However, after the disappearance of the ... Webin proactively avoiding incast congestion. To address this problem, in this paper, we propose a new application layer solution, called Proactive Incast Congestion Control (PICC) for a datacenter serving web applications. The root cause of the incast congestion problem is the many-to-one concurrent communications between the single front-end
