Introduction The term network virtualization refers to the creation of logical isolated network partitions overlaid on top of a common enterprise physical network infrastructure, as shown in Figure 1. Figure 1 Creation of Virtual Networks Each partition is logically isolated from the others, and must provide the same services that are available in a traditional dedicated enterprise network. The end user experience should be as if connected to a dedicated network providing privacy, security, an independent set of policies, service level, and even routing decisions. At the same time, the network administrator can easily create and modify virtual work environments for various user groups, and adapt to changing business requirements adequately. The latter is possible because of the ability to create security zones that are governed by policies enforced centrally these policies usually control or restrict the communication between separate virtual networks or between each logical partition and resources that can be shared across virtual networks. Because policies are centrally enforced, adding or removing users and services to or from a VPN requires no policy reconfiguration. Meanwhile, new policies affecting an entire group can be deployed centrally at the VPN perimeter. Thus, virtualizing the enterprise network infrastructure provides the benefits of using multiple networks but not the associated costs, because operationally they should behave like one network reducing the relative OPEX costs. Network virtualization provides multiple solutions to business problems and drivers that range from simple to complex. Simple scenarios include enterprises that want to provide Internet access to visitors guest access. The stringent requirement in this case is to allow visitors external Internet access, while simultaneously preventing any possibility of unauthorized connection to the enterprise internal resources and services. This can be achieved by dedicating a logical virtual network to handle the entire guest communication path. Internet access can also be combined with connectivity to a subset of the enterprise internal resources, as is typical in partner access deployments. Another simple driver for network virtualization is the creation of a logical partition dedicated to the machines that have been quarantined as a result of a Network Admission Control NAC posture validation. In this case, it is essential to guarantee isolation of these devices in a remediation segment of the network, where only access to remediation servers is possible until the process of cleaning and patching the machine is successfully completed. Complex scenarios include enterprise IT departments acting as a service provider, offering access to the enterprise network to many different customers that need logical isolation between them. In the future, users belonging to the same logical partitions will be able to communicate with each other and to share dedicated network resources. However, some direct inter communication between groups may be prohibited. Typical deployment scenarios in this category include retail stores that provide on location network access for kiosks or hotspot providers. The architecture of an end to end network virtualization solution targeted to satisfy the requirements listed above can be separated in the following three logical functional areas Access control Path isolation Services edge Each area performs several functions and must interface with the other functional areas to provide the end to end solution see Figure 2. Figure 2 Network Virtualization Framework The functionalities highlighted in Figure 2 are discussed in great detail in separate design guides, each one dedicated to a specific functional area.

The path isolation functional area is the focus of this guide. This guide mainly discusses two approaches for achieving virtualization of the routed portion of the network Policy based network virtualizationRestricts the forwarding of traffic to specific destinations, based on a policy, and independently from the information provided by the control plane. A classic example of this uses ACLs to restrict the valid destination addresses to subnets in the VPN. Control plane based network virtualizationRestricts the propagation of routing information so that only subnets that belong to a virtual network VPN are included in any VPN specific routing tables and updates. This second approach is the main core of this guide, because it allows overcoming many of the limitations of the policy based method.
