Long flows could potentially block the transmission of delay-sensitive short flows, leading to degraded performance.  ...  In today's data center, a diverse mix of throughput-sensitive long flows and delay-sensitive short flows are commonly presented in shallow-buffered switches.  ...  Fastlane [25] is an agile congestion notification mechanism, which aims at informing the sender as quickly as possible to throttle the transmission rate by sending explicit, high-priority drop notifications  ...
