Logical Network Diagraming

Logical Network Diagrams visualize the telecommunication and computer networks logical structure. They are used by IT professionals and corporate IT departments, network and system administrators to visually document the logical topology of computer networks.

ConceptDraw has 1004 vector stencils in the 40 libraries that helps you to start using software for designing your own Logical Network Diagrams.

You can use the appropriate stencils from Computer and Network Diagrams object libraries.

Network Diagram Software Home Area Network

Even if you design a network for yourself, you still might need a network diagram software to do it in a convenient way. Your laptop, or PC, a smartphone and a router form a home area network, which might be very small, but has to fulfill all your requirements. A schematic diagram will help you to arrange all the cables and network devices in a proper way. This wireless network diagram is made to describe the home-area network system. This diagram shows the typical wireless network organization in a private house or condominium. It consists from computers and gadgets that use wireless connections. The diagram is created using the ConceptDraw Computer Networks Diagrams solution. It is a rather common diagram that features icons depicting Wi-Fi point, router, media gadgets and periphery with connections and routes that show the flow of data.Wireless router home area network diagram - Computer and Networks solution sample

Local area network (LAN). Computer and Network Examples

Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams. This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.Local area network (LAN). Computer and Network Examples

Cisco Network Design

Enterprise systems engineers almost every day face the necessity of network diagrams. We should also take into account that Cisco network design is not only limited to computer networks, but, furthermore, you can design telephone networks and much more. You can build an hierarchical model of your network to get better performance and reliability. This network diagram represents the utilization of Conceptdraw PRO for network documentation creation. The diagram shows schematically the structure of a node of a large Internet service provider, which is completed on the basis of Cisco equipment. This diagram was designed using the vector library containing the images of Cisco equipment, supplied with Cisco Network Diagrams solution. In total, the solution has more than ten libraries including more than 500 vector icons of Cisco equipment.Cisco network diagram - Network diagram example

How to Draw a Computer Network Diagrams

Planning a computer network can be a challenge for a junior specialist. However, knowing how to draw a computer network diagrams isn’t a rocket science anymore. There are a lot of special software for creating such diagrams with predesigned templates and examples. The core for Network Fault Tolerance System presented here, is the equipment of Cisco. You can see here the certified Cisco equipment icons. Generally, ConceptDraw PRO libraries contain more than half of a thousand objects representing the standardized images of Cisco equipment. ConceptDraw solution for network diagramming is a great network diagramming tool for any level skills - from students to network guru.Computer Network Diagram

Star Network Topology

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.Star Network Topology

Network diagrams with ConceptDraw PRO

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.Network diagram

Network Topologies

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.Common Network Topologies Diagram

Personal area (PAN) networks. Computer and Network Examples

All computer networks differ by various params, and their size is one of them. As global area networks are the biggest, personal area (PAN) networks are the smallest. Personal computers, smartphones and other devices that have possibility to connect to Internet form a personal network. This diagram was created using ConceptDraw Computer Network Diagrams to represent a typical components of Personal area network. A personal area network (PAN) is the connection of IT devices around an individual person. This sample of personal area network involves a notebook, a personal digital assistant (PDA), and a portable printer. Commonly a PAN contains such wireless devices as mouse, keyboard, smartphone and tablet. A wireless connection is typical for a PAN.Personal area (PAN) networks. Computer and Network Examples
