[内容简介]

Chapter 1 concerns virtualization techniques that allow sharing computational resources, slicing a real computational environment into virtual computational environments that are isolated from each other. 
Chapter 2 presents Xen and OpenFlow virtualization platforms and provides a performance analysis of both. This chapter also defines the primitives that the network virtualization infrastructure must provide to allow the piloting plane to manage virtual network elements. Afterwards, interfaces for system management of the two platforms are proposed in Chapter 3. To control and manage virtual network elements, five primitives that the network virtualization infrastructure must provide are defined: instantiate, delete, migrate, monitor, and set. Chapter 6 surveys existent control algorithms for virtual networking. This chapter also describes the main challenges for packet forwarding using Xen as a virtualization tool and describes in more detail a proposal for local control of virtual networks. Within each physical node, this proposal guarantees the service level acquired by each virtual network, even in the presence of misbehaved virtual networks.
