Network diagrams with ConceptDraw PRO
While documenting computer network it is often necessary to describe the existing network structure with the help of schemes or diagrams. It is required to document network configuration, used protocols, logical structure of the network, addresses and names of network objects. Network diagram is the tool for description, study and analysis of network knots and connections between these knots. Created network diagram can present you the existing information in comprehensible graphic view.
Network diagrams are divided into Physical Network Diagrams and Logical Network Diagrams.
As a rule at the development of diagrams ready sets of symbols and pictures for indication of network knots, connections between knots and information about diagram objects are used.
Outer objects, for instance Internet, out of network are described in the form of clouds. Depending on the diagram destination necessary level of the detailed elaboration of the diagram is selected. For instance, on the diagram there can be presented only network objects, such as computers and servers without indication of their parameters and connections type. Similar diagram presents the information about the general structure of the network and is not overloaded with excessive details. Besides, diagrams of different levels of the network contain different types of objects. On the diagram of LAN level (local area network) computers, printers, servers, etc. are displayed whereas on the diagram of WAN level (wide area network) whole buildings and even cities are displayed.
Physical Network Diagram presents to user following information:

Network TopologiesWhen 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.
Mesh Network Topology DiagramThe reliability is a cornerstone for any corporate computer network. If you want to provide a high fault tolerance, a mesh network topology would be the solution. The main advantage of this network is that every node can work as a commutator, although itвЂ™s not easy to set up this kind of network. A mesh network topology may be full, or partial. Full mesh network means that each node of the network (computer, workstation or other equipment) is connected directly to each of the other nodes. A partial mesh topology means that a part of nodes are connected with a whole network, and the other part of nodes are only connected to those equipment, they exchange the majority of data. This illustration shows schematic diagram of a partial mesh network containing six nodes. Each node is represented as a circles and connections are drawn as straight lines. The connections may be both wired and wireless. This scheme can be used to make the specific logical or physical network diagrams by means the ConceptDraw Computer and Networks solution.
Active Directory DiagramIt's no secret that there is a list of skills that every average system administrator should have. And it's important to be able to manage domains via active directory technologies. The best way to keep all the details in mind is to draw a diagram representing users, groups and domains. This diagram represents an Active Directory Services (Active Directory Domain Services). It can be helpful for system and network administrators to organize a network physical and logical elements (domains, data bases, servers, network equipment, end-user computers etc.) into a secure and logical structure. The logical structure of Active Directory is a hierarchical organization of all network components. The data that is stored in Active Directory comes from some diverse sources. The Active Directory diagram created using ConceptDraw Active Directory Diagram solution. It shows allocating group policies and functions assigned to end users. It helps to plan, manage and maintain the certain user access scenario.

Wide area network (WAN) topology. Computer and Network ExamplesStudying informatics demands knowledge in the area of computer networks as well. The most famous world network, Internet, is an example of wide area network (WAN) topology that connects devices spread on any distance. Unlike other smaller networks that are limited to a building or to a campus, WAN is almost limitless. This WAN (wide area network) diagram was created in ConceptDraw PRO. It shows a telecommunication network that covers a large geographical area connecting several settlements. This type of networks is commonly used by business and government institutions. Using the WANs enables them quickly communicate information between remote geographical points. To reproduce this network diagram, you will need the means, provided by ConceptDraw Computer and Network Diagrams solution.
Star Network TopologyNodes 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.
Network Glossary DefinitionWhen 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 PRO 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.
ConceptDraw PRO Network Diagram ToolCreating a detailed network plan can cause a lot of headache to an unexperienced user. And it is worth mentioning that ConceptDraw PRO is a decent tool for creating a network diagram, a tool that is easy-to-use. To get an accurate diagram use the vector shapes from the special libraries that represent workstations, network appliances, wiring systems and connect them with smart-connectors, just as simple as that. This communication network diagram displays the way different components of a computer network communicate with each other. When representing network information, such as depicting all the equipment in a large network, it is helpful to make visual representation. Network diagram provides an easy way to show the way the connections between an equipment in a large network. This diagram of a communication network depicts a network composed of three sub-networks. It uses a network equipment symbols to represent the different devices that make up a network communication including routers, Ethernet devices and end-point equipment.
