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 LAN - Vector stencils library

The vector stencils library "Cisco LAN" contains 23 symbols of local area network (LAN) devices and equipment for drawing Cisco LAN topology diagrams.
"Network topology describes the layout of interconnections between devices and network segments. At the Data Link Layer and Physical Layer, a wide variety of LAN topologies have been used, including ring, bus, mesh and star, but the most common LAN topology in use today is switched Ethernet. At the higher layers, the Internet Protocol (TCP/ IP) has become the standard, replacing NetBEUI, IPX/ SPX, AppleTalk and others.
Simple LANs generally consist of one or more switches. A switch can be connected to a router, cable modem, or ADSL modem for Internet access. Complex LANs are characterized by their use of redundant links with switches using the spanning tree protocol to prevent loops, their ability to manage differing traffic types via quality of service (QoS), and to segregate traffic with VLANs. A LAN can include a wide variety of network devices such as switches, firewalls, routers, load balancers, and sensors.
LANs can maintain connections with other LANs via leased lines, leased services, or the Internet using virtual private network technologies. Depending on how the connections are established and secured in a LAN, and the distance involved, a LAN may also be classified as a metropolitan area network (MAN) or a wide area network (WAN)."

The symbols example "Cisco LAN - 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.
