Design and Implementation of a Cloud-Federation Agent for Software Defined Networking

This paper introduces a cloud-federation agent which enables a horizontal network federation between different cloud providers, based on Software Defined Networking (SDN). Furthermore, tenants, using the cloud´s Infrastructureas a Service (IaaS) model, have a fine grained access to the resources via an exposed Open Flow interface, deployed on top of the SDN router´s virtualized control plane. This provides complete management and control capabilities of a virtual SDN (vSDN) substrate and gives tenants the freedom to deploy virtual network-appliances or services using Network Function Virtualization (NFV) on top of the allocated vSDN.
