Network virtualization is using network resources through a logica segmentation of a single physical network. Network virtualization is achieved by installing software and services to manage the sharing of computing cycles and applications Network virtualization treats all servers and services in the network as a single pool of resources that can be accessed without regard for its physical components. The term network virtualization is often used to describe many things including network managementstorage virtualization, and even grid computing.

By deploying and managing network resources as logical services rather than physical resources, companies can:

• Enhance enterprise agility.

• Improve network efficiency.

• Reduce capital and operational costs.

• Maintain high standards of security, scalability, manageability, and availability throughout the campus design.

LAN virtualization can consolidate multiple physical networks into one virtual network OR logically segment a single physical network into multiple logical networks. Partitions can be added to rapidly scale the network for business needs.
