A virtual network is a computer network that consists, at least in part, of virtual network links. A virtual network link is a link that does not consist of a physical (wired or wireless) connection between two computing devices but is implemented using methods of network virtualization.
The two most common forms of network virtualization are protocol-based virtual networks (such as VLANs, VPNs, and VPLSs) and virtual networks that are based on virtual devices (such as the networks connecting virtual machines inside a hypervisor). In practice, both forms can be used in conjunction.
Virtual LANs (VLANs) are logical local area networks (LANs) based on physical LANs. A VLAN can be created by partitioning a physical LAN into multiple logical LANs using a VLAN ID. Alternatively, several physical LANs can function as a single logical LAN. The partitioned network can be on a single router, or multiple VLANs can be on multiple routers just as multiple physical LANs would be. A VLAN can be on a VPN.
VMware Workstation is a hosted hypervisor that runs on x64 versions of Windows and *nix operating systems (an x86 version of earlier releases was available); it enables users to set up virtual machines (VMs) on a single physical machine, and use them simultaneously along with the actual machine. Each virtual machine can execute its own operating system, including versions of Microsoft Windows, Linux, BSD, and MS-DOS. VMware Workstation is developed and sold by VMware, Inc., a division of EMC Corporation. An operating systems licence is needed to use proprietary ones such as Windows. Ready-made Linux VMs set up for different purposes are available.
VMware Workstation supports bridging existing host network adapters and sharing physical disk drives and USB devices with a virtual machine. It can simulate disk drives; an ISO image file can be mounted as a virtual optical disc drive, and virtual hard disk drives are implemented as .vmdk files.
VMware Workstation Pro can save the state of a virtual machine (a "snapshot") at any instant. These snapshots can later be restored, effectively returning the virtual machine to the saved state, as it was and free from any post-snapshot damage to the VM.
Network bridging is the action taken by network equipment to create an aggregate network from either two or more communication networks, or two or more network segments. If one or more segments of the bridged network are wireless, it is known as wireless bridging. Bridging is distinct from routing, which allows multiple different networks to communicate independently while remaining separate.
A network bridge is networking hardware that connects multiple network segments. In the OSI model, bridging is performed in the first two layers, below the network layer.
There are four types of network bridging technologies: simple bridging, multiport bridging, learning or transparent bridging, and source route bridging.
A transparent bridge uses a forwarding database to send frames across network segments. The forwarding database is initially empty and entries in the database are built as the bridge receives frames. If an address entry is not found in the forwarding database, the frame is flooded to all other ports of the bridge, flooding the frame to all segments except the one from which it was received. By means of these flooded frames, the destination network will respond and a forwarding database entry will be created.

Hi This tutorial is based on how to create a virtual network using ORACLE VIRTUALBOX.
This is part of a complete series at http://azure.msts2.com. This video will walk through the Virtual Network creation process in Microsoft Azure.
Learn more by visiting: http://cs.co/9001B2dl9. True network virtualization requires end to end path isolation. Attempts to do this in the past have never made it easy for all network engineers until now. The Fundamentals of Cisco Easy Virtual Network will give you the foundation for understanding what makes this so valuable.
http://kb.vmware.com/kb/1018697 This video guides you through using the Virtual Network Editor in VMware Workstation. The video covers adding adapters, removing adapters, and modifying adapters. The video also covers changing DHCP settings and configuring NAT, including configuring the incoming port. This video was created using VMware Workstation 7, but the same basic steps apply other versions of VMware Workstation. For more information about using VMware Workstation, see http://www.vmware.com/support/pubs/ws_pubs.html
Overview of VMware Virtual Networks on VMware Workstation. As you may already know, you access the Virtual Network Editor by clicking Edit then Virtual Network Editor... After a fresh install of VMware Workstation we have the default virtual networks of VMnet0 as a Bridged network, VMnet1 as a Host-only network and VMnet8 as a NAT network. Let's step through a Bridged network, a Host-only network and NAT network and discuss what they are, why to use them and how to configure each. The first virtual network is a Bridged network. A Bridged network is one where the Guest OS shares the Host network adapter in connecting to the physical network. The Guest OS uses the same DHCP Server, DNS Server and Gateway as the Host OS. You can only have one Bridged network per physical network adap...
