In this paper we present VeRTIGO (ViRtual TopologIes
Generalization in OpenFlow networks), a Software–defined
networking platform designed for network virtualization. Based
on the OpenFlow original network slicing system FlowVisor,
the VeRTIGO platform aims at covering all flavors of network
virtualization: in particular, it is able to expose a simple abstract
node on one extreme, and to deliver a logically fully connected
network at the very opposite end.
In this work, we first introduce the VeRTIGO system architecture
and its design choices, then we report on a prototypical
implementation deployed over an OpenFlow–enabled testbed.
Experimental results show that VeRTIGO can deliver flexible
and reliable network virtualization services to a wide range of
use cases in spite of failure and/or congestion at the underlying
physical network.
