Complex Cloud Datacenters

The network architecture deployed in a data center is of extreme importance and should provide the data center with the high throughput while keeping overprovisioning at the minimum costs. In order to provide these features new complex network based models have been proposed recently. In this paper we give an overview of the proposed models and their characteristics, advantages and problems. We then propose a new datacenter network model that provides easy subgrouping while preserving high bandwidth and low average path length and network diameter.
