Incast congestion

WebApr 1, 2024 · The many-to-one traffic pattern in datacenter networks leads to Transmission Control Protocol (TCP) incast congestion and puts unprecedented pressure to cloud service providers. The abnormal TCP behaviors in incast increase system response time and unavoidably reduce the applicability of cloud-based system deployments. This paper … 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

WebJan 1, 2015 · Impairments such as TCP Incast, TCP Outcast, Buffer pressure, Queue build-up and pseudo-congestion effect severely degrade the performance of traditional TCP variants in DCNs. With cloud computing becoming an important part of the forseeable future, it is extremely crucial to eliminate these impairments. WebIncast congestion typically happens in a data center network when multiple servers, all connected to the same switch, are sending data simultaneously to a common destination, such that the switch buffer overflows, resulting in packet loss.
