It is said that the next leap in data center virtualization is network virtualization. Networking is a key area that really needs to be virtualized, as there are numerous virtual machines that can move around the enterprise. With servers running at 90 percent capacity the network infrastructure needs to scale to give the same level of bandwidth and performance. Network virtualization is a promising approach to cover individual and dynamic resource provision that is intended to improve productivity, efficiency, and job satisfaction of the administrator. Although it aims to optimize network speed, reliability, flexibility, scalability, and security, network virtualization is said to be especially effective in networks that experience sudden, large, and unforeseen surges in usage. It provides a powerful way to run multiple networks, each customized to a specific purpose, at the same time over a shared substrate.
Network virtualization is classified as either external, combining many networks, or parts of networks, into a virtual unit, or internal, providing network-like functionality to the software containers on a single system. Regardless of whether it is internal or external, the benefits have many other advantages. With network virtualization, there is a conceptual layer that divides that physical network device from the business services on the network. Consequently there is an infrastructure that is a whole lot more flexible and efficient.
Bandwidth management is the underlying principle behind network virtualization. To enable bandwidth applications at affordable costs, most network managers use numerous WAN connections. By managing the bandwidth and optimizes network speed there is an overall reduction in the cost. With network virtualization business continuity can be achieved as virtualization isolates the network impact of multiple applications and minimizes downtime. This way, not only does automated provisioning diminish expensive configuration errors, applications also do not get in each other’s the way.
Generally a tedious and time-consuming business for a human administrator, network virtualization also undertakes network management. The true complexity of the network is concealed as in network virtualization the system performs these functions automatically. Network virtualization also facilitate companies to increase enterprise deftness, enhance network competence, reduce capital and operational costs and continue and maintain extraordinary levels of security, scalability, manageability and availability. Most of the functions can be centrally managed from a single physical site and this simplifies the tasks. Network virtualization is particularly effective and useful in those networks that frequently experience sudden, large and unpredicted surge in usage.
