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 WebAn Incast-Coflow-Aware Minimum-Rate-Guaranteed Congestion Control Protocol for Datacenter Applications. Abstract: Today s datacenters need to meet service level objectives (SLOs) for applications, which can be translated into deadlines for (co)flows running between job execution stages.
