"Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. Essentially, it is the topological structure of a network, and may be depicted physically or logically. Physical topology refers to the placement of the network's various components, including device location and cable installation, while logical topology shows how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, and/ or signal types may differ between two networks, yet their topologies may be identical. The study of network topology recognizes eight basic topologies: Point-to-point, Bus, Star, Ring or circular, Mesh, Tree, Hybrid, Daisy chain." [Network topology. Wikipedia]
The computer network topologies diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

"A bus network is a network topology in which nodes are connected in a daisy chain by a linear sequence of buses. ...
The bus is the data link in a bus network. The bus can only transmit data in one direction, and if any network segment is severed, all network transmission ceases.

A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic, and the traffic generated by each station has equal transmission priority. Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable simultaneously, they use a media access control technology such as carrier sense multiple access (CSMA) or a bus master." [Bus network. Wikipedia]

"Physical topology refers to the placement of the network's various components, including device location and cable installation...
The shape of the cabling layout used to link devices is called the physical topology of the network. This refers to the layout of cabling, the locations of nodes, and the interconnections between the nodes and the cabling. The physical topology of a network is determined by the capabilities of the network access devices and media, the level of control or fault tolerance desired, and the cost associated with cabling or telecommunications circuits."

"Network Mapping Software.
A number of software tools exist to design computer network diagrams / or generate visual maps of networks, servers, storage, services, data centers, and other peripherals. Broadly, there are two types of software tools - those that help create diagrams manually and those that generate them using automated / semi-automated approaches.
Type of Software.
(1) Manual - allows users to design and draw logical and physical topology diagrams by manually placing icons and connections.
(2) Automated - generate topology diagrams / maps by traversing the network and automatically discovering resident devices or by importing network data." [Comparison of network diagram software. Wikipedia]
ConceptDraw PRO is the software for manual design of computer network diagrams. The solutions of the Computer and Networks area in ConceptDraw Solution Park extend ConceptDraw PRO with vector stencils libraries, templates and examples for creating the computer network diagrams.

How to Open Visio® VDX File Using ConceptDraw DIAGRAM

MS Visio file with the extension. VDX can be created with the MS Visio 2003-2007. It is a filename extension for the MS Visio XML drawing file format. MS Visio 2010 and earlier versions support reading and writing files in a binary VSD or XML-based VDX file formats. Since MS Visio 2013 drawing files are written in the new VSDX and VSDM file formats. The writing VDX files are no longer supported. If you used MS Visio 2003-2010 before and now is considering to switch to ConceptDraw DIAGRAM v12, maybe this is a good news - ConceptDraw DIAGRAM v12 is still supported reading and writing of Microsoft Visio XML file format. Thus replacing the diagramming software, allows keeping all your drawings, created in the old versions of MS Visio. Making business drawings with ConceptDraw DIAGRAM v12 is easier than using MS Visio. Moreover, you will be able to use a huge number of business-oriented libraries supplied by ConceptDraw Solutions. Also, using ConceptDraw you can create your custom objects and supplement libraries to cover your requirements.

"Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. Network planning process involves three main steps: 1) Topological design: This stage involves determining where to place the components and how to connect them. 2) Network-synthesis: This stage involves determining the size of the components used, subject to performance criteria such as the Grade of Service (GoS). 3) Network realization: This stage involves determining how to meet capacity requirements, and ensure reliability within the network."
