In this chapter, we introduced the concept of network virtualization and, in particular, the role and functionality of FlowVisor as a tool for network slicing in OpenFlow-based networks. The FlowVisor API and related structures for flow matching and slice actions were presented and a use case experiment was explained in this chapter. Now you are aware of the tools that can be used to slice a network and control each slice in an innovative way.
In the next chapter, we will look at the roles of OpenFlow and SDN in general in cloud computing.
