Computer Network Diagrams

Today it is impossible to imagine any human activity without the use of computers and computer networks, which provide abilities of fast communication and rapid exchange of information. A computer network is a combination of nodes (computers and network equipment), which are connected with communication channels and switching equipment in a common system to exchange the messages and to provide for all network users the access to common program, technical, informational and organizational resources of the network. A computer network consists at least of two computers, which interact with each other. Depending on the remoteness of computers and the scope, the networks are divided into the local and global. The local area network connects the group of computers and is typically deployed on a small limited area, within some organization, building or small group of buildings, office, home, university, school or any other premise. The global area networks cover large geographical areas from the hundreds to thousands kilometers, include large number of computers, and can also contain the local area networks, telecommunication networks and other devices. The global area networks are intended for unlimited number of subscribers, but offer the smaller speed than the local networks. Sometimes, it is allocated the intermediate class of networks, such as urban or regional networks located within specific cities, regions, etc.

The computers can be connected at the networks in various ways. The logical and physical ways of connecting computers, cables and other components of a network are called its topology. The physical topology specifies the geometric arrangement of network nodes, communication lines relatively to network nodes and physical connections of nodes, while the logical topology describes the flow of data between network nodes and data transmission methods. The network topology determines the main characteristics of the network and can be of several types. The basic topologies are Bus, Star, Ring, each of them has its advantages and disadvantages. The network topology in which all computers are connected to a central hub with a point-to-point connection, is named Star topology. If the computers are connected along a single cable, such topology is called Bus. When the connecting cable is closed in a ring, topology is called Ring. At this, the logical and physical network topologies will not necessarily be the same. Moreover, in real networks can be often found the complicated combinations joining the properties of several topologies.

Example 3: Bus Network Topology Diagram

This diagram was created in ConceptDraw PRO using the Computer Network and Network Hardware Libraries from the Computer Network Diagrams Solution. An experienced user spent 5 minutes creating this sample.

Network topology is the arrangement of various elements of a computer network. There are many types of computer network topologies. This sample diagram visualizes one of them - the Bus Network Topology. It is a network topology in which the nodes are connected to a main (bus) cable that can transmit the data only in one direction. This topology is a simplest, inexpensive, quick in installation and quite flexible, but the damage of some bus cable segment leads to the failure of the entire network and the data transmission suspends, at this the failure of some node not affects on the work of the entire network. Besides this topology type well suits only for the networks with small quantity of nodes, vice versa great quantity of nodes leads to the reduction of network performance, the length of the bus cable is also limited and the speed of data transmission is quite low.

Example 8: LAN Topology Diagram

This diagram was created in ConceptDraw PRO using the Computer Network, Computers and Network Isometric, Network Hardware, Logical Network Diagram, and Computer Peripheral Devices Library from the Solution. An experienced user spent 10 minutes creating this sample.

A Local Area Network (LAN) is a computer network mounted on a limited territory, such as home, school, university, laboratory, office, or some other premise or building, which interconnects the computers within this defined area using the special network equipment, wired or wireless technologies. LAN is characterized by the limited number of computers and high data rate, large bandwidth and low level of transmission errors, the use of well-protected communication lines and effective mechanism of management the data exchange at the network. The configuration of network components and their connections is described by the network topology that defines requirements for the hardware, for the type of used cable, for work reliability, capability of extension, and many others. This diagram shows topology of the local area network (LAN), i.e. schematic of the physical arrangement of computers and network devices included in a given computer network, as well as their connection by communication lines.

Example 9: Logical Bus with a Physical Star

This diagram was created in ConceptDraw PRO using the Computer Network, Computers and Network Isometric, Network Hardware, Logical Network Diagram, and Computer Peripheral Devices Library from the Solution. An experienced user spent 10 minutes creating this sample.

Each local area network is organized with some network topology that is a way in which devices are arranged at the network and communicate with each other. It is differentiated the logical and physical network topology, moreover the logical topology not obligatory must to be the same as a physical topology of this network. This Computer network topology diagram sample is a classic example of the network organized with a Star physical topology and Bus logical topology. It is a common case, because very often the network organized with logical bus physically is connected as a star. Each computer on this diagram is linked to the central hub device with an individual cable and all peripheral devices are connected to the appropriate computers. The bus logical topology prescribes that the spread of data packages is realized so that all network nodes receive the message and each node checks it is addressed to him or not.

Example 10: Network Topologies Diagram

This diagram was created in ConceptDraw PRO using the Computer Network, Computers and Network Isometric, Network Hardware, Logical Network Diagram, and Computer Peripheral Devices Library from the Solution. An experienced user spent 10 minutes creating this sample.

The network topology is the arranged set of different elements of a computer network, such as nodes (computers, electronic devices, network equipment, etc.) and links. The network topological structure can be represented physically or logically. If the logical topology describes the data flows within a network, which not depend from the network's physical design, the physical topology displays in details the placement of all network's components, depicts the precise location of all computer and network devices, and cables linking them. Two networks with a same logical topology can differ by physical interconnections, transmission rates, distances between nodes, and signal types. It is known eight types of network topologies: Star, Bus, Ring, Point-to-point, Mesh, Tree, Daisy chain, and Hybrid. This sample demonstrates a variety of kinds of computer network topologies. You can observe and compare schematics of the Fully Connected network topology, Mesh network topology, Start network topology, Common Bus topology, and Ring network topology.

Example 11: Network Vaccine Architecture

This diagram was created in ConceptDraw PRO using the Computer Network, Computers and Network Isometric, Network Hardware, Logical Network Diagram, and Computer Peripheral Devices Library from the Solution. An experienced user spent 10 minutes creating this sample.

Different kinds of viruses, Trojans, worms, bots and other malwares represent a serious threat for software of computers and other electronic devices. The worms are ones of the most widespread. They are the type of malwares, which are able to self-spread through the local networks and the Internet by creating the copies of themselves. Worms are independent software that do not require other files or host programs, as well as a human's assistance for malicious work and distribution. They enter to the computer to attack it through a system's vulnerability. This computer network diagram example was drawn on the base of the illustration from the webpage "Software & System Assurance. Autonomic Software Patching" placed on a website of the Network Security Lab at Columbia University's Computer Science Department. It depicts the network worm vaccine architecture that is well-known and incredibly useful system developed for automatic patching and defense the systems and networks from the attacks of worms or other network threats.

Visual Documentation of a Corporate Computer Network

Small and medium-sized companies have network infrastructure which can total ten or more networking and computing devices (computers, servers, printers, telephones, routers, fax machines, scanners, etc.) All elements of a network have their own settings configured for fast and reliable service. As a company grows, it is necessary to incorporate new devices into the network, update existing devices, change the network topology, and even add new subnets. Changing the configuration of the network is only possible if there is documentation of the operating infrastructure.

To achieve high-quality documentation of network infrastructure, it is necessary to include the overall network structure topology, a communication scheme, the layout of the main devices, the scheme arrangement of servers in server racks, the list of installed services, services and databases for each server, and the scheme of corporate PBX.

The Computer and Networks solution provides a set of templates for documenting such office network infrastructure. It includes 5 templates and sample documents for more than 10 different diagrams. They are:

  1. Network Logical Structure Diagram
    The Network Logical Structure Diagram is designed to show the logical organization of a network. Shows the basic network components, network structure, and determines the interaction of all network devices. The diagram displays basic devices and zones: Internet, DMZ, LAN, and group. Clarifies what network equipment is connected, describes the major nodes in the network, gives an understanding of the logical structure of the network as well as the type of interaction within the network.
