【 摘 要 】

We present Gatekeeper, a distributed rate control mechanism that supports network link bandwidth guarantees for multiple co-located tenants in a virtualized datacenter. Gatekeeper provides network performance isolation across tenants by enforcing link bandwidth allocations for both egress and ingress network traffic at each physical host. Experiments on our Xen-based implementation of Gatekeeper in a datacenter cluster demonstrate effective control of link bandwidth for both TCP and UDP traffic, and for a Hadoop-based application running concurrently with streaming workloads.
