We analyze the defects of window-based TCP algorithm in datacenter networks and propose Rate-based Datacenter (RDT) this paper. The RDT combines rate-based congestion control technology with ECN (Explicit Congestion Notification) mechanism DCTCP. experiments NS2 show that has a potential to completely avoid incast collapse datacenters inherit low latency advantages
