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.
Virtual may refer to:
Networking and networking may refer to:
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.
In computing, a virtual machine (VM) is an emulation of a particular computer system. Virtual machines operate based on the computer architecture and functions of a real or hypothetical computer, and their implementations may involve specialized hardware, software, or a combination of both.
Various different kinds of virtual machines exist, each with different functions. System virtual machines (also known as full virtualization VMs) provide a complete substitute for the targeted real machine and a level of functionality required for the execution of a complete operating system. A hypervisor uses native execution to share and manage hardware, allowing multiple different environments, isolated from each other, to be executed on the same physical machine. Modern hypervisors use hardware-assisted virtualization, which provides efficient and full virtualization by using virtualization-specific hardware capabilities, primarily from the host CPUs. Process virtual machines are designed to execute a single computer program by providing an abstracted and platform-independent program execution environment. Some virtual machines, such as QEMU, are designed to also emulate different architectures and allow execution of software applications and operating systems written for another CPU or architecture. Operating-system-level virtualization allows the resources of a computer to be partitioned via the kernel's support for multiple isolated user space instances, which are usually called containers and may look and feel like real machines to the end users.

Abraham Matta - October 28, 2016 The virtualization of network functions (e.g., load balancer, intrusion detection system) has enabled the deployment of such functions anytime and anywhere. This webinar discusses the deployment of a Virtual Network Function (VNF) and challenges associated with the cost and performance of delivering its service. Specifically, VNF instances can be dynamically deployed to meet changing conditions, i.e., more (less) instances to accommodate higher (less) traffic demand or more (less) stringent service requirements. To illustrate these issues, we present a basic set of GENI experiments on a topology that contains traffic sources, a destination, VNF instances of an intrusion detection system (i.e., Snort), an Open vSwitch (OVS), and a controller. The controller...
Networks in modern datacenters are populated with a large and increasing variety of proprietary hardware appliances. Hardware cycles inhibit the rolling out of new revenue generating services, and constrain innovation in an increasingly network-centric and connected world. Network Functions Virtualization (NFV) looks to leverage virtualization technologies and move this hardware-centric network equipment onto Virtual Machines on top of commercial-off-the-shelf (COTS) hardware. Each of these network elements are called Virtual Network Functions (VNFs). This session provides an introduction to Microsoft efforts in NFV including the set of VNFs that will be delivered along in the next release of Windows Server.

Using demonstrations throughout, he explains the Virtual Machine storage architecture and shows how to provision and customize virtual machines, configure network connectivity between virtual machines, and configure site-to-site networks that enable true applications that span from on-premises to Windows Azure. He'll focus specifically on features that enable you to create highly available Virtual Machine-based services and how to connect Virtual Machines with Cloud Services.
we will bring an NSX infrastructure online in a running physical environment – a powerful example of migrating to a virtual infrastructure with no downtime. We will discuss the linking of physical devices to the edge services gateway and configuring routing protocols on network devices and in the NSX environment. We will also explain why a clear knowledge of your ecosystem, from the physical switch on up, will help you better understand how the overlay and the underlay come together. This master class picks up after the software has been installed, at the point when you need to start securing and passing packets in your environment. This session will include: - A deep dive into setting up the physical and virtual network infrastructure. - Demos you can follow to get NSX quickly running in...
