The first chapter of this title concerns virtualization
techniques that allow sharing computational resources basically,
slicing a real computational environment into virtual computational
environments that are isolated from one another.
The Xen and Open Flow virtualization platforms are then presented in
Chapter 2 and a performance analysis of both is provided. This
chapter also defines the primitives that the network virtualization
infrastructure must provide for allowing the piloting plane to
manage virtual network elements.
Following this, 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.
The book then moves on to survey existing control algorithms for
virtual networking. It 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
misbehaving virtual networks.
