Today's enterprises have several groups of users with specific needs. The differences between these groups translate into specific network requirements. As the number of groups increases, keeping them separate and secure is a challenge to IT departments, particularly with the advent of wireless networks, the requirement for enterprise-wide user mobility, and the need for cross-group collaboration with resource sharing on a per-project basis.
Network Virtualization provides design guidance for virtualized enterprise networks and arms network architects with the background necessary to make sound technological choices in the face of different business requirements.
In this chapter: Technical requirements posed by the need to virtualize the network are defined. Based on these requirements, the authors propose an architectural framework comprised of the functional areas necessary to successfully support concurrent virtual networks over a shared enterprise physical network. They also discuss security considerations of defining a network perimeter.
