Transport Control Protocol (TCP) in cast congestion happens in high-bandwidth and low-latency networks when multiple synchronized servers send data to the same receiver in parallel. For many important data-center applications such as MapReduce and Search, this many-to-one traffic pattern is common. Hence TCP in cast congestion may severely degrade their performances, e.g., by increasing response time. In this paper, the authors study TCP incast in detail by focusing on the relationships between TCP throughput, Round-Trip Time (RTT), and receive window.
