Overlay networks.
Computer and Network Examples
An Overlay network is a computer network that is built on the top of another network. The nodes of the overlay network are connected by virtual or logical links.
Overlay networks are widely used in telecommunication. They also allow to improve Internet routing.
The overlay networks are sufficiently complex. They consist of the logical layers that are built and operated by different entities with general concerns. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Overlay network broken up into the logical layers.

OSPF is an interior gateway protocol (IGP), it is widely used in large enterprise networks. OSPF routes the IP packets within a single routing domain. It gathers the information about the link state from the routers and makes the network topology map.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the OSPF diagram.

Cisco switches and hubs deliver the best performance, and often used as network solutions for small businesses, enterprises, data centers. Cisco switches are the core interconnect devices of each computer network. The numerous Cisco switches specifically designed for various applications. Network switches are separated for two types: fixed configuration and modular switches. The fixed configuration switches deprecate swapping or adding another module, and vice versa for modular switch.

If you have a small budget to design a computer network, you have to be very careful. One of the most cheap technologies to implement is a bus network topology, however it has many disadvantages. For instance, if the network cable is somehow damaged, the entire network won't work.
This diagram illustrates a so-called "Bus" network topology. This type of network arrangement means that each computer or other device is linked to a main link (bus). The end nodes are shown as a circle. The links to the bus are depicted as solid vertical lines. The bus is shown as a bold horizontal line. This diagram can serve as a template for creating logical or physical network diagrams. The set of vector libraries supplied with ConceptDraw Computer and Networks solution contains the symbols of all LAN and WLAN elements required for creating network diagrams of any configuration.

Studying informatics demands knowledge in the area of computer networks as well. The most famous world network, Internet, is an example of wide area network (WAN) topology that connects devices spread on any distance. Unlike other smaller networks that are limited to a building or to a campus, WAN is almost limitless.
This WAN (wide area network) diagram was created in ConceptDraw DIAGRAM. It shows a telecommunication network that covers a large geographical area connecting several settlements. This type of networks is commonly used by business and government institutions. Using the WANs enables them quickly communicate information between remote geographical points. To reproduce this network diagram, you will need the means, provided by ConceptDraw Computer and Network Diagrams solution.

The Enhanced Interior Gateway Routing Protocol (EIGRP) is a progressive distance-vector dynamic routing protocol. It was developed by the Cisco Systems and is available as an open standard from 2013.
EIGRP is used to help automate routing decisions and configuration of the computer network. It allows the routers of the same logical area automatically share route information.
