Incast congestion
WebJun 1, 2014 · Congestion occurs when synchronized servers under the same Gigabit Ethernet switch simultaneously send data to one receiver in parallel .Only after all connection have finished the data transmission can the next round be issued. Thus these connections are called barrier-synchronised. 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.
