Virtual networks. Computer and Network Examples

A Virtual network is a computer network that consists of virtual network links, i.e. between the computing devices there isn't a physical connection.
Well known forms of network virtualization are virtual networks based on the virtual devices (for example the network based on the virtual devices inside a hypervisor), protocol-based virtual networks (VLAN, VPN, VPLS, Virtual Wireless network, etc.) and their combinations.

VMware vNetwork Distributied Switch (vDS). Computer and Network Examples

The VMware vNetwork Distributed Switch (vDS) is the new virtual switch (vSwitch) with vSphere 4 that extends the set of features of the VMware vNetwork Standard Switch (vSS). The VMware vSS is the base-level virtual networking alternative that extends the capabilities, configuration and appearance of the standard vSwitch in VMware ESX 3.5 to ESX 4.0 and vSphere 4.
This example was created in ConceptDraw PRO using the Computer and Networks Area of ConceptDraw Solution Park and shows the VMware vDS network diagram.

Physical network. Computer and Network Examples

Physical network represents the computer network topology that includes the computer devices, location and cable installation. Physical network includes the actual nodes, segments and hosts.
