Network Topology Design
Network Topology Diagrams visualize the telecommunication and computer network topology and layout. They display the arrangement of the various elements of the computer network and how they communicate.
ConceptDraw DIAGRAM is a powerful diagramming and vector drawing software for designing professional looking computer network topology diagrams of any complexity.
The Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park provides templates, samples and 40 libraries with 1004 vector objects that make your computer network topology diagramming easy, quick and effective.
Example 1. Network Topology Design
This sample shows the network topology diagram of the devices connection to the Internet. It was designed in ConceptDraw DIAGRAM using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.
The diagrams produced with ConceptDraw DIAGRAM are vector graphic documents and are available for reviewing, modifying, and converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio).

SIX RELATED HOW TO's:
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.

A network diagram represents the set of computers and network devices and the connections among them. This scheme can be developed for any institution or establishment. To illustrate this concept let’s take for example, a hotel network topology diagram or a school network diagram. These diagrams depict access points, servers, workstations, firewalls and another equipment needed to provide a network.
On this masterpiece drawing one will see a simple scheme a of connecting computers together. Such form of connecting can be applied for a hotel, guest house, bungalow, hut or something else. This diagram shows the images of the real LAN components. So, it represents a physical category of a network construction. It looks similar to a star - so this network configuration is named a star topology. The typical feature of this construction is a center point - usually it is hub, or router. The rays of this star means network connections. Computers, peripherals and other network details are placed on the ends of the star rays.

Nodes of any computer network are somehow organized in a hierarchy or a layout. Some of the common layouts like star network topology are more reliable and some like ring topology withstand high loads better. It is also important to distinguish logical topologies from physical.
This diagram represents a typical view of the star network topology. The star network topology is one of the most frequently used network topologies in the majority of office and home networks. It is very popular because of its low cost and the easy maintenance. The plus of the star network topology is that if one computer on the local network is downed, this means that only the failed computer can not send or receive data. The other part of the network works normally. The minus of using star network topology is that all computers are connected to a single point-switch, or hub. Thus, if this equipment goes down, the whole local network comes down.

This sample shows the Point-to-point network topology.
Network topology is the topological structure of the computer network.
Point-to-point network topology is a simple topology that displays the network of exactly two hosts (computers, servers, switches or routers) connected with a cable. Point-to-point topology is widely used in the computer networking and computer architecture.

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 DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the VMware vDS network diagram.

Of course it is possible to keep network records in text documents, but it is very difficult to use them later. A more sound way to keep such documentation is to create a network diagram that might represent either logical network structure or physical. These diagrams are easy to understand and you will thank yourself later.
There is a physical network diagram. It is a tool to represent, maintain and analysis of network equipment and interconnections. Network diagram depicts the actual network information in the attractive clear graphic form. One can learn here the LAN cable length, telecommunication type and carrying capacity. The diagram depicts servers, IP address and domain name as well. Also it shows location of hubs, switches, modems, routers, and other network equipment. The sets of special symbols and images delivered with ConceptDraw Network Diagrams solution are used to show network components. Symbols have a standard view. Therefore, various specialists can read the network diagram without any discrepancies.
