Gatekeeper: Supporting Bandwidth Guarantees for Multi-tenant Datacenter Networks
نویسندگان
چکیده
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.

Cicada: Introducing Predictive Guarantees for Cloud Networks
In cloud-computing systems, network-bandwidth guarantees have been shown to improve predictability of application performance and cost [1, 28]. Most previous work on cloud-bandwidth guarantees has assumed that cloud tenants know what bandwidth guarantees they want [1, 17]. However, as we show in this work, application bandwidth demands can be complex and time-varying, and many tenants might lac...
متن کاملEyeQ: Practical Network Performance Isolation at the Edge
The datacenter network is shared among untrusted tenants in a public cloud, and hundreds of services in a private cloud. Today we lack fine-grained control over network bandwidth partitioning across tenants. In this paper we present EyeQ, a simple and practical system that provides tenants with bandwidth guarantees as if their endpoints were connected to a dedicated switch. To realize this goal...

متن کاملEnabling Work-conserving Bandwidth Guarantees for Multi-tenant Datacenters via Dynamic Tenant- eue Binding
Today’s cloud networks are shared among many tenants. Bandwidth guarantees and work conservation are two key properties to ensure predictable performance for tenant applications and high network utilization for providers. Despite significant efforts, very little prior work can really achieve both properties simultaneously even some of them claimed so. In this paper, we present QShare, an in-net...
