Chapter 7

The Virtualization Layer—Performance, Packaging, and NFV


In this chapter, we will look at the evolution of virtualization techniques and software network I/O acceleration to satisfy these application requirements. We will also look at how the constant evolution in the compute component of the (ETSI-labeled) “NFVI” might affect the current aggregated, VM-centric NFV model, our concept of Service Function Chaining and the potential economic assumptions behind the NFV proposition.

Proponents of NFV see applications that stretch from the replacement of individual fixed network appliances (eg, firewall) through reimagination ...
