Overlay network.
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.

This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Overlay network diagram for the P2P network.

Example 1. Computer and Network Area.

Peer-to-peer (P2P) network is a virtual overlay network on top of the physical network topology. In the overlay its nodes form the subset of the nodes in the physical network. The nodes are equal peer nodes. At the application layers the peers exchange data via the logical overlay links. Overlays are used for indexing and peer discovery. They also make the P2P system independent from the physical network topology. The networks can be structured and unstructured in depending on how the nodes are linked each other.

Near field communication (NFC) is a wireless communication technology that allows smartphones and other similar devices to establish the radio communication with each other on the short distance around 10 centimeters (4 inches). This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Near field communication (NFC) network.

Network Topologies →

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.
