STCC: A SDN‐oriented TCP congestion control mechanism for datacenter network

Abstract Due to characteristics of high bandwidth and low latency, datacenter networks ensure tremendous data could be transmitted in an efficient way. However, in many‐to‐one transmission scenarios, high concurrency of TCP flows aggravates network congestion and causes overflows in switches, seriou...
