云环境应该为虚拟化数据中心中共处一地的不受信任租户提供网络性能隔离。我们提出了性能隔离解决方案应该满足的关键属性，并介绍了我们在网守上的进展，网守是一个旨在满足这些要求的系统。我们的基于Xen-based实现的数据中心集群中的网守的实验表明，有效和灵活的控制下的TCP和贪婪的无响应UDP流量的租户虚拟机的入口/出口链路带宽。
Cloud environments should provide network performance isolation for co-located untrusted tenants in a virtualized datacenter. We present key properties that a performance isolation solution should satisfy, and present our progress on Gatekeeper, a system designed to meet these requirements. Experiments on our Xen-based implementation of Gatekeeper in a datacenter cluster demonstrate effective and flexible control of ingress/egress link bandwidth for tenant virtual machines under both TCP and greedy unresponsive UDP traffic.
