Multi-tenant datacenters represent an extremely challenging networking environment.
Tenants want the ability to migrate unmodified workloads from their enterprise networks to …

Providers of" Infrastructure-as-a-Service" need datacenter networks that support multi-
tenancy, scale, and ease of operation, at low cost. Most existing network architectures …

In this paper, we propose virtual data center (VDC) as the unit of resource allocation for
multiple tenants in the cloud. VDCs are more desirable than physical data centers because …

The shared nature of the network in today's multi-tenant datacenters implies that network
performance for tenants can vary significantly. This applies to both production datacenters …

Cloud environments should provide network performance isolation for co-located untrusted
tenants in a virtualized datacenter. We present key properties that a performance isolation …

Emerging data-center network designs seek to provide physical topologies with high
bandwidth, large bisection capacities, and many alternative data paths. Yet, existing …

BACKGROUND Server virtualization allows multiple virtual machines (VM) to run on a single
physical server. Virtualization allows users to move their servers to a" cloud and to take …

This paper presents Blender, a framework that enables network operators to improve tenant
performance by tailoring the network's behavior to tenant needs. Tenants may upgrade their …

BACKGROUND Data center network research often demands a datacenter environment
with a number of hosts, with virtualization Sup port and Switches to connect these hosts. A …

While virtual machine (VM) migration is allowing data centers to rebalance workloads across
physical machines, the promise of a maximally utilized infrastructure is yet to be realized …
