Network Diagram Examples

Network diagram is a chart which represents nodes and connections between them in computer network or any telecommunication network, it is a visual depiction of network architecture, physical or logical network topology. There are used common icons for the Network diagrams design, such as icons of various network appliances, computer devices, routers, clouds, peripheral devices, digital devices, etc. Network diagrams can represent networks of different scales (LAN level, WAN level) and detailization. ConceptDraw DIAGRAM diagramming software enhanced with Computer Network Diagrams solution from Computer and Networks area includes huge collection of computer and network templates, design objects and stencils, and numerous quantity of Network diagram examples and samples, among them: Basic Computer Network Diagrams, Communication Network Diagram, Wireless Router Network Diagram, LAN Topology Diagram, Computer Network System Design Diagram, Mobile Satellite Communication Network, Web-based Network Diagram, Hybrid Network Diagram, and many others.

Roaming wireless local area network diagram

"There are two definitions for wireless LAN roaming:
Internal Roaming (1): The Mobile Station (MS) moves from one access point (AP) to another AP within a home network because the signal strength is too weak. An authentication server (RADIUS) performs the re-authentication of MS via 802.1x (e.g. with PEAP). The billing of QoS is in the home network. A Mobile Station roaming from one access point to another often interrupts the flow of data among the Mobile Station and an application connected to the network. The Mobile Station, for instance, periodically monitors the presence of alternative access points (ones that will provide a better connection). At some point, based on proprietary mechanisms, the Mobile Station decides to re-associate with an access point having a stronger wireless signal. The Mobile Station, however, may lose a connection with an access point before associating with another access point. In order to provide reliable connections with applications, the Mobile Station must generally include software that provides session persistence.
External Roaming (2): The MS (client) moves into a WLAN of another Wireless Internet Service Provider (WISP) and takes their services (Hotspot). The user can independently of his home network use another foreign network, if this is open for visitors. There must be special authentication and billing systems for mobile services in a foreign network." [Wireless LAN. Wikipedia]
This Cisco roaming wireless local area network diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

Cisco Network Diagrams solution extends ConceptDraw DIAGRAM with the best characteristics of network diagramming software. Included samples, templates and libraries of built-in standardized vector Cisco network icons and Cisco symbols of computers, network devices, network appliances and other Cisco network equipment will help network engineers, network designers, network and system administrators, as well as other IT professionals and corporate IT departments to diagram efficiently the network infrastructure, to visualize computer networks topologies, to design Cisco computer networks, and to create professional-looking Cisco Computer network diagrams, Cisco network designs and schematics, Network maps, and Network topology diagrams in minutes.

LAN topology diargam

"A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines. Ethernet over twisted pair cabling, and Wi-Fi are the two most common technology standards currently used to build LANs." [Local area network. Wikipedia]
This local area network (LAN) topology diargam 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.

Physical LAN and WAN diagram - Template

"At different scales diagrams may represent various levels of network granularity. At the LAN level, individual nodes may represent individual physical devices, such as hubs or file servers, while at the WAN level, individual nodes may represent entire cities. In addition, when the scope of a diagram crosses the common LAN/ MAN/ WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes. For example, if a network appliance is intended to be connected through the Internet to many end-user mobile devices, only a single such device may be depicted for the purposes of showing the general relationship between the appliance and any such device." [Computer network diagram. Wikipedia]
The physical LAN and WAN diagram template for the ConceptDraw PRO diagramming and vector drawing software is included in the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

Network Layout

The Network Layout Diagram visually illustrates the arrangement of computers, nodes and other network appliances, such as servers, printers, routers, switches, hubs, and their relationships between each other. The network layout and placement of servers greatly influence on the network security and network performance. Elaboration of robust Network Layout Diagram is especially important when visualizing already existing network in order to understand its complexity; when troubleshooting the network issues; designing, documenting and implementing new network configurations; extending, modifying, or moving an existing network to other location. Through the careful thinking the network plan and designing the clear Network Layout Diagram, you can be confident in result on the stage of network implementation and to solve faster the problems appearing in network infrastructure. ConceptDraw DIAGRAM enhanced with Computer Network Diagrams solution from Computer and Networks area perfectly suits for drawing Network Layout Diagrams for different network topologies.

Cisco Network Templates

Cisco is a huge multinational company that develops and sells worldwide the]network equipment, mainly for large organizations and telecommunication companies. So, it has large number of enterprise clients in a corporate environment. Therefore many network engineers often draw the Network diagrams for Cisco hardware and are needed in a powerful vector drawing software. ConceptDraw DIAGRAM is ideal for this goal, enhanced with professional Cisco Network Diagrams solution from Computer and Networks area of ConceptDraw Solution Park it offers a wide variety of vector design objects libraries, samples and also large set of Cisco network templates. The use of templates is the easiest and time-saving way of drawing professional-looking diagrams and schematics. Use them to design Cisco Network Topologies, Cisco Network Diagrams, Cisco ISG Topology Diagrams, Cisco Express Forwarding Diagrams, Rack Diagrams, Network Organization Charts, Wireless Computer Network Diagrams, Vehicular Network Diagrams, and many other types of diagrams without efforts.
