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.

VLAN (Virtual LAN) is a logical LAN (local area network) based on the physical LAN that is divided on a multiple logical LANs using a VLAN ID.

VLAN can be on a VPN (virtual private network). VPN consists of several remote end-points (such as routers, VPN gateways of software clients) that are connected by the tunnel over another network. Two connected end points form the PTP VPN (Point to Point Virtual Private Network), more than two end points form a Multipoint VPN.

VPLS (Virtual Private LAN Service) is a specific type of Multipoint VPN. They can be Transparent LAN Services (TLS) that provides geographic separation and Ethernet Virtual Connection Services (EVCS) that provides geographic separation and VLAN subnetting.

Virtual Wireless network is a set of Wireless Access Points that behaves as one. Computer and Networks Area for ConceptDraw DIAGRAM provides professional looking examples, the libraries with ready-to-use predesigned vector stencils to help you create the Virtual Networks quick, easy and effective.

Cisco Network Design. Cisco icons, shapes, stencils, symbols and design elements →

Talking about companies, that have influenced the entire industry, we should mention Cisco and it’s influence on network design. Nowadays, this equipment has became a kind of standard, and Cisco icons, shapes, stencils, symbols and design elements are easily recognized among others. You can use these icons to develop a network diagram of any complexity. When dealing with creating a pack of network documentation, system administrator often have to depict a network containing a network equipment of such a well-known manufacturer as Cisco. As Cisco has developed its own production standard icons that are strongly recommended to use in Cisco network diagrams. The best way to draw Cisco Network diagram Cisco certified icons is using ConceptDraw solution for Cisco Network Diagrams. Using Cisco symbols library provided by this solution allows system administrator, or network architect to design a prototype of a new network or document an existing one.Cisco Network Design.

Network Glossary Definition →

When talking about engineering, one should define all the terms used, so anybody could understand the topic. Typical network glossary contains definitions of numerous network appliances, types of networks and cable systems. The understanding of basic is crucial for server management, network administration and investigating problems. The network glossary defines terms related to networking and communications. The most of glossary items has their visual representation in ConceptDraw DIAGRAM libraries of the Computer Network Diagrams solution. This illustration presents a local area network (LAN) diagram. It designed to show the way the interaction of network devices in a local network. The diagram uses a library containing symbols of network equipment, connections and the end-point devices such as network printer, hubs, server, modem and finally computers (PC, mac, laptop). This diagram depicts a physical LAN topology.Network Glossary Definition *

Today, we can’t imagine our lives without daily data exchange. To call a set of devices that can be connected with each other a computer network, we must be sure that these devices support appropriate protocols to transfer data. A network consisting of personal devices is private, and global computer networks, for example, Internet, connects network nodes worldwide. This diagram represents a computer telecommunication network. The network depicted on the current diagram is featured with networked communication devices that provide data exchange through Internet. The network interconnections and connections between Internet nodes are settled using the cable media and wireless media. The nodes are the network workstations (terminals). and host computers.

Hypercube Network Topology →

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park. This sample shows the Hypercube network topology. Network topology is the topological structure of the computer network. Hypercube is a type of the toroidal network. The Torus is a topology with n-dimensional grid network with circularly connection of the nodes. If the number of nodes along each dimension of the toroidal network is 2, it is a Hypercube network topology.Hypercube Network Topology *

Tree Network Topology Diagram →

When designing a network, it is important to take into account the hierarchy of network devices. When you have a root device you should consider a tree network topology that might have any number of lower levels as you might need. This technology is based on star and bus network topologies. This is a schematic representation of a Tree computer network topology. A tree topology means that some star networks are linked together. A star network is a topology of the local network where a central workstation is connected with each end-user computer or peripherals. A tree structure means that, the central nodes of these star networks are linked to a main cable (the Bus topology). So, a Tree network topology is a few Star networks connected into a Bus topology. This scheme can be applied to draw the particular physical or logical network diagrams using the ConceptDraw Computer and Networks solution.Tree Network Topology Diagram *
