# Butterfly Network. Computer and Network Examples

ConceptDraw DIAGRAM v12 extended with Computer and Networks solution is a powerful network diagramming and vector drawing software that allows you easy and quick draw professional looking Butterfly Networks. For this purpose Computer and Networks solution provides the large quantity of ready-to-use predesigned vector stencils and examples.

The Butterfly Network is the scheme that connects the units of a multiprocessing system and needs n stages to connect 2n processors. At the each stage the switch is thrown in depending of the particular bit in the addresses of the processors that are connected.

The Butterfly Network has two sources. Each of them has the value A or B. There are two destination nodes which want to know both A and B. Each edge carries only a single value.

Example 1. Butterfly Network

This example was created in ConceptDraw DIAGRAM v12 using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park and shows the Butterfly Network.

The network diagrams designed with ConceptDraw DIAGRAM v12 are vector graphic documents and are available for reviewing, modifying, and converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio).

### 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.

### 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 v12 using the Computer and Networks Area of ConceptDraw Solution Park and shows the Overlay network diagram for the P2P network.
