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 …

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

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 …

To be agile and cost effective, data centers should allow dynamic resource allocation across
large server pools. In particular, the data center network should enable any server to be …

To be agile and cost effective, data centers must allow dynamic resource allocation across
large server pools. In particular, the data center network should provide a simple flat …

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 …

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 …

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 …

Today's data centers may contain tens of thousands of computers with significant aggregate
bandwidth requirements. The network architecture typically consists of a tree of routing and …

In this paper, we propose an unorthodox topology for datacenters that eliminates all
hierarchical switches in favor of connecting nodes at random according to a small-world …
