Network Virtualization (NV) is one of the most promising approaches to enable innovation in today’s network. Generally speaking, NV refers to the possibility of pooling together low–level hardware and software resources belonging to a networked system into a single administrative entity. In such a way network resources could be effectively shared in a transparent way among different logical network instances corresponding to different virtual network topologies. A recent approach toward Network Virtualization has been proposed through FlowVisor [1], whose aim is to leverage on the specific features of an OpenFlow–controlled network [2] to share the same hardware forwarding plane among multiple logical networks.

Abstract
Network Virtualization (NV) is one of the most promising approaches to enable innovation in today’s network. Generally speaking, NV refers to the possibility of pooling together low–level hardware and software resources belonging to a networked system into a single administrative entity. In such a way network resources could be effectively shared in a transparent way among different logical network instances corresponding to different virtual network topologies. A recent approach toward Network Virtualization has been proposed through FlowVisor [1], whose aim is to leverage on the specific features of an OpenFlow–controlled network [2] to share the same hardware forwarding plane among multiple logical networks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
