WebJan 11, 2024 · Datacenters host a mix of applications which generate qualitatively distinct traffic patterns and impose varying network objectives. Online, user-facing applications generate many-to-one, incast traffic of mostly short flows, which are sensitive to tail of Flow Completion Times (FCT). Data analytics applications generate all-to-all traffic (e.g., Web … 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.

WebIncast Congestion leading to internal packet loss 1. During incast scenario, ingress queue counter doesn’t exceed the PFC threshold, so will not send PFC Pause frame to upstream. Packet will always come in from ingress port. Ingress queue counter Ingress queue counter 2. But the physical egress queue has backlog because of convergence effect. 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
