Network Diagramming with ConceptDraw PRO

At the moment computer networks are widespread, various types of computer networks are constructed around the world, operate and interact with each other. There are many kinds of computer networks that differ in the transmission medium, in communications protocols, in size, topology, organizational intent, and also in territorial basis. There are popular such types of computer networks as Global Area Network (GAN), Wide Area Network (WAN), Metropolitan Area Network (MAN), Local Area Network (LAN). ConceptDraw PRO is a powerful network diagramming software, perfect for software engineers, software designers and software developers who need to draw Computer Network diagrams, designs, schematics, and network maps in no time. The pre-drawn shapes representing computers, network devices and smart connectors offered by ConceptDraw solutions help to create the accurate diagrams and documentation, represent computer network topologies and designs, depict Computer network architectures, logical, physical, cable networks, and vehicular networks.

Cisco WAN - Vector stencils library

The vector stencils library "Cisco WAN" contains 15 symbols of wide area network (WAN) devices and equipment for drawing Cisco WAN diagrams.
"A wide area network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, or national boundaries) using leased telecommunication lines. Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations. ...
Related terms for other types of networks are personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively.
... it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different LANs, MANs and other localised computer networking architectures. ...
WANs are often built using leased lines. At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. Network protocols including TCP/ IP deliver transport and addressing functions. Protocols including Packet over SONET/ SDH, MPLS, ATM and Frame relay are often used by service providers to deliver the links that are used in WANs." [Wide area network. Wikipedia]
The symbols example "Cisco WAN - Vector stencils library" 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.
