                                 Network Virtualization

What is Network Virtualization

         Network virtualization represents the administration and monitoring of an entire computer network as a single administrative entity from a single software-based administrator’s console.

How does network virtualization work?

Network virtualization decouples network services from the underlying hardware and allows virtual provisioning of an entire network. It makes it possible to programmatically create, provision, and manage networks all in software, while continuing to leverage the underlying physical network as the packet-forwarding backplane. Physical network resources, such as switching, routing, firewalling, load balancing, virtual private networks (VPNs), and more, are pooled, delivered in software, and require only Internet Protocol (IP) packet forwarding from the underlying physical network.

Demonstrate a Network Virtualization in Oracle VM Box 

STEP 1 : Create a virtual machine 

 enter a name for virtual machine

Randomly choose your  Memory size 

Choose a hard disk 

virtual machine has created as "SNEKA"

STEP 2 : Navigate to settings , choose Network 

In Adapter 1,  choose "enable network adapter" , attached to choose "Internal Network"

name as "intnet" , then click advanced choose the adapter type "IntelPRO"

In Adapter 2 ,also choose the enable network adapter  and click OK

STEP 3 : Start your virtual machine , here i have attached a "windows.iso" file 

choose "open network and sharing center" 

click change adapter settings

Here you can see network has configured as Ethernet 1 and Ethernet 2 and network type as 

"IntelPRO"
