Chapter 4. A Virtualization Technologies Primer: Theory
This chapter covers the technology used to build virtualized networks (VNs). As discussed previously, virtualization is not just about IPsec tunnels in the WAN—it covers a wide range of technology options on routers and switches. There are virtual partitions on routers and switches and protocol extensions that combine to maintain the end-to-end coherency of VNs across a shared infrastructure. We consider virtualization in three main sections:
Devices—. How is traffic separation maintained internally to a device? What are the primitives used for Layer 2, Layer 3, or Layer 4 traffic?
Data path—. How is traffic separation enforced across a network path? What tools are available to maintain the ...
