What does Network Virtualization mean?
Network virtualization refers to the management and monitoring of an entire computer network as a single administrative entity from a single software-based administrator’s console. Network virtualization also may include storage virtualization, which involves managing all storage as a single resource. Network virtualization is designed to allow network optimization of data transfer rates, flexibility, scalability, reliability and security. It automates many network administrative tasks, which actually disguise a network's true complexity. All network servers and services are considered one pool of resources, which may be used without regard to the physical components.
Network virtualization is especially useful for networks experiencing a rapid, large and unpredictable increase in usage.
The intended result of network virtualization is improved network productivity and efficiency, as well as job satisfaction for the network administrator.
