There are three major approaches to the virtualization of network services:
- The first, referred to as network virtualization (NV), is a network tunnel. This version is used to create tunnels through an existing network to connect two separate domains. This is done as an alternative to physically connecting two network domains. Using tunnels is valuable because it avoids physical labor associated with physically installing new domain connection. This concept is even more critical when needed to connect virtual machines. NV also efficiently leverages capital investments in existing infrastructure thus avoiding additional capital outlays. When network virtualization is used with high-performance x86 platforms, movement ...
