Carving Research Slices Out of Your Production Networks with OpenFlow

http://conferences.sigcomm.org/sigcomm/2009/demos/sigcomm-pd-2009-final65.pdf

Network slicing implies that actions in one slice do not negatively affect other slices, even if they share the same underlying physical hardware.

A common network slicing technique is VLANs. With VLANs, the administrator partitions the network by switch port and all traffic is mapped to a VLAN by input port or explicit tag.

Centralized policy enforcement
All control traffic, from switch to controller and from controller to switch, traverses the FlowVisor.
Decouple control and virtualization technologies
Rather than building virtualization support directly into the OpenFlow protocol itself, we intentionally keep the control and virtualization aspects orthogonal. This allows each technology to evolve independently, avoiding new forms of ossification.
