Like the virtualization of storage is network virtualization to disconnect the software from the underlying hardware . The networking is done through virtual switches and routers.
The basis of network virtualization are two techniques: feature virtualization of networks, NFV (network functions virtualization ) and software-defined networking, sdn (software -defined networking ) . They can be used separately or together.
Simply put, virtualization is function of the operators and data networks with extremely high volumes where the underlying networks are different.
Software Defined Networking is primarily used in the data center and hardware consists of standardized servers, switches and routers.
An example application is to add or remove network shares. Network Virtualization can also be used to merge or split the network and still use the same underlying hardware.
To succeed with virtualization , it is important to have a good structure of the network and the IP addresses.
It is a great opportunity to do a review of your own network environment when preparing to start using network virtualization, says Emanuel Lipschütz , CEO of Netsafe .
- In critical environments such as data centers are proven solutions preferable and when you build new today is that the virtualization technology that applies. Network Virtualization lets companies consolidate and do more with less equipment.
Virtualization also makes it easier for non-techies to affect network traffic. This can be done by dividing the software to the higher and lower priority levels with regard to communication. Then you can start putting prices on network resources and move decisions on the use of networks to business units.
- One can imagine a simple administration interface where business managers can choose between network services with price tags of 50, 100 or 150 crowns per unit time. Meanwhile, network managers a more sophisticated interface, where they can monitor and analyze the network from a technical perspective , based on various network attributes, storage locations and server resources , said Carla Arend , an analyst at IDC.
- Business People just need to care about the cost, while the techniques he takes on the technical aspects of the operation .
To traditional virtual networking solutions to work, some excess capacity in the underlying physical network. Otherwise , you can not " bounce " network resources. A software- defined networks could take advantage of the underlying network resources to 100 percent.
