Datacenters support a variety of applications and tenants with vastly different requirements, imposing several challenges on the underlying network. Large, bandwidth hungry, flows share the same network with smaller, latency-sensitive flows. Traffic from multiple tenants or applications can congest a common bottleneck link, leading to delays that are an order-of-magnitude higher than an uncongested case. In this talk, I'll present two mechanisms that can reduce the impact of congestion in datacenter networks by allowing administrators to dictate the behavior of flows at the "edge." That is, instead of making expensive upgrades to network equipment, administrators can provision simple lightweight changes in server software to obtain network-wide performance benefits and also enforce fine-grained control over traffic in their network.
