Metropolitan area networks (MAN). Computer and Network Examples

A Metropolitan Area Network (MAN) is a great computer network located on the large geographical area or region. It is a network bigger than Local Area Network (LAN), but territorially smaller than Wide Area Network (WAN), its diameter usually ranges from 5 to 50 kilometers. MAN usually includes several buildings or even the whole city (metropolis). It is based on high data rate compounds using the fiber channels and other digital data transmission channels. MAN includes a lot of communicating devices, for its construction are used multiple routers, switches and hubs. MAN can combine together several Local Area Networks or Campus Area Networks located in different buildings within a city and provides the Internet connectivity for them. Solutions included to Computer and Networks Area for ConceptDraw Solution Park are the real godsend for those who want design Computer Network Diagrams, and among others the Metropolitan Area Network Diagrams. They offer the libraries with ready-to-use vector design elements, professional-looking examples, samples and templates.

Hybrid Network Topology

A network topology is the topological structure or the arrangement of different elements of computer network. There are several basic types of network topologies, such as star, ring, bus, mesh. But the most popular is a combination of two or more diverse basic network topologies, which is known as hybrid network topology. The examples of hybrid topology are: star-bus, star-ring topologies, etc. Each resulting hybrid topology has its own features, advantages and limitations of its components. Hybrid network topologies are more flexible, reliable, and have increased fault tolerance, the faults in them can be easily diagnosed and corrected, new nodes can be easily added. But at the same time hybrid topologies often are sufficiently expensive and difficult for managing. ConceptDraw DIAGRAM diagramming and vector drawing software supplied with the tools of Computer Network Diagrams solution from Computer and Networks area is perfect for schematic description various types of computer network topologies and easy designing Hybrid network topology diagrams.

Cisco Network Design. Cisco icons, shapes, stencils, symbols and design elements

Cisco is the largest company, which specializes in the field of high technologies, develops and sells network equipment mainly for the large organizations and telecommunication companies. Cisco produces wide variety of devices and equipment, such as routers, switches, gateways, servers, network security devices (firewalls, VPN, IDs, etc.), ATM switches, cable modems and DSL equipment, access points Wi-Fi, products for IP telephony, etc. The first commercially successful multi-protocol router, which enabled for previously incompatible computers to communicate between themselves, is also developed by Cisco company. Cisco is a generally accepted standard, which uses globally recognized Cisco icons for all produced Cisco equipment. ConceptDraw DIAGRAM software extended with Cisco Network Diagrams solution from Computer and Network area contains a lot of predesigned Cisco network design elements for professional drawing Cisco network diagrams, visualization computer network topologies, equipment connections and arrangement.

Network wiring cable. Computer and Network Examples

To connect two or more network devices are used the network cables. There are more different types of the network cables: Coaxial cable, Optical fiber cable, Twisted Pair, Ethernet crossover cable, Power lines and others. They are used depending of the network topology, size, protocol. This example was created in ConceptDraw DIAGRAM using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

Network diagrams with ConceptDraw DIAGRAM

Network diagram is effective tool for representing and description the network knots and connections between them in comprehensible graphic view, for studying and analysis them. The network administrators and engineers actively use Physical Network Diagrams and Logical Network Diagrams, which are both indispensable when developing and documenting new networks, and managing existing ones. Network diagrams let clearly represent the network configuration and structure, used protocols, addresses, and also names of network objects. Physical Network Diagrams depict the information about telecommunications data, servers, location of network equipment and number of network users. Logical Network Diagrams describe about logical network structure. It is useful to use the ready sets of network clipart, pictures and symbols for indication the network knots on a diagram, such as developed by professionals and offered in large quantity by Computer Network Diagrams solution from ConceptDraw Solution Park.

Star Network Topology

Star is a basic computer network topology in which all nodes (computers and peripheral devices) of the network are connected to the central hub or switch with a point-to-point connection, forming a physical network segment. Such network segment can function separately or as a part of complex network topology. The switch is a server, the peripherals are the clients. The large workload and functions of network management are entrusted on the central computer, all information exchange goes through it, so it must to be obligatory the most powerful. The star network topology is a simple topology for design and implementation. Its advantages are high performance, flexible administration capabilities, simplicity of adding additional nodes and search of faults, the fact that a failure of one workstation doesn't affect the work of entire network. But the failure of central hub will result the failure of whole network or network segment - it's the main disadvantage. Use the ConceptDraw DIAGRAM with Computer and Networks solution to designing Star Network Topology Diagrams fast and easy.

UML Diagram Types List

Two types of diagrams are used in UML: Structure Diagrams and Behavior Diagrams. Behavior Diagrams represent the processes proceeding in a modeled environment. Structure Diagrams represent the elements that compose the system.
